What is Plastisol? A Durable Dip Coating Solution



Plastisol is a PVC-type coating in plasticizing liquids. At room temperature, Plastisol is a liquid; when heated or cured, the liquid turns to a flexible, rubber-like barrier.


Once applied, Plastisol coating is practically indestructible, making it ideal for numerous high-impact applications.


Why Use Plastisol?

Plastisol coating is renowned for extreme corrosion resistance, but there is much more to it than that.


This coating is tough, making it nearly impossible to damage with impact – it will not chip or fray. Plastisol is often applied to components as a preventative measure to reduce wear or eliminate rattling. It also boasts impressive chemical resistance.


Although it is a PVC-based coating, Plastisol has a soft, almost rubberized feel. It is comfortable and easy to grip and boasts terrific sound-deadening properties. It can be used to reduce the wear on parts and eliminate rattling.


As an insulator with high dielectric strength, this coating also many electrical applications, including electrical sheathing.


How Is It Applied?

Plastisol begins as a fluid mixture of PVC particles and additives. In this non-processed liquid state, it can be poured into a mould or applied in a dipping process. Plastico Industries utilizes several carousel lines and a small monorail line for Plastisol dip coating.


The product is first preheated in an oven. Once the product reaches the determined temperature, it is lowered into the Plastisol solution. The product is coated and then returned to an oven for curing, which converts the liquid to its hardened state.


The thickness of the coating can be controlled by the temperature to which the product is preheated. The higher the preheat temperature, the thicker the coating. Lower temperatures deliver a thinner coating.


Is Plastisol Applied to the Whole Product?

The process of applying Plastisol allows for unlimited flexibility in coating.


In most cases, Plastisol is applied to the whole product, creating an indestructible seal around the piece. When customers ask for only a small portion of a product to be protected with Plastisol, the product is partially dipped to the desired coating requirement and then cured.


So, How Durable is It?

Plastisol offers many advantages not found in other coating options. It delivers a lifetime of protection to the product and is flexible in its composition.


Hardening agents can be added to deliver a cured hardness up to a Shore durometer rating of 90, which is harder than the plastic on a hard hat, while UV inhibitors protect against fading from the sun’s damaging rays.


Additionally, Plastisol has natural anti-bacterial and anti-microbial properties and can even be formulated to meet FDA food grade requirements.


What Industries Use Plastisol Coating?

Plastisol bonds well to any metal substrate when properly primed and its extreme durability makes it the coating of choice for applications across every industry. The applications for coated products are wide-ranging. Industries that use Plastisol coating include Forestry, Mining, Aviation, Automotive and Heavy Machinery.


Its flexibility also lends this coating to small and delicate products. Locksmiths understand the advantages of a Plastisol coating, as even the tiniest of lock picks receive this durable coating solution.


Plastisol is also the coating of choice for outdoor municipal playground structures. With its extreme durability, UV protection and sound deadening properties, it’s no wonder why most playground equipment is coated with Plastisol!

What Makes Nylon Coating Unique?

From a cost-per-part perspective, a nylon powder coating is typically costlier than traditional powder coatings. That hasn’t stopped nylon from becoming the material of choice for some of the most demanding metal coating applications, from crucial automotive parts to life-saving medical devices.


What makes nylon coatings stand out from traditional polyester coatings? To start, nylon delivers a standard of performance and durability that few materials can match. But it also sets itself apart as an environmentally-friendly choice that eases the burden of a manufacturer’s carbon emissions.


metal coating


Here’s what makes nylon powder a leading metal coating option:


1. Nylon Coating is Renewable, Recyclable and Environmentally-Friendly

Nylon powder coating is derived primarily from vegetable oil extracted from castor beans. These so-called ‘beans’ are the seeds of the Ricinus or castor oil plant, which can be grown and harvested with little to no carbon impact. With nylon powder coating, you can reassure your customers that the part is coated with an environmentally-safe, low-impact material.


2. Nylon Coating is Extremely Durable

It may come from a plant, but nylon powder coating is tough as nails. It goes on thin at .004 to .030 thousandths of an inch and hardens into a resilient coat. With impressive thermal, physical and mechanical properties, nylon coating dependably protects metal parts from chemicals, corrosion, abrasions, oil and fluids, and high impacts.


3. Nylon Coating Meets Autoclave Requirements

Few materials can withstand the rigours of the autoclave. Nylon powder coating meets the standards of autoclaving requirements, making it the coating of choice for many important medical industry applications.


4. Nylon Coating is Quiet

Noise isn't always the first thought when it comes to choosing a powder coating solution, but more and more manufacturers are turning an ear to the impact of noise on workplace health and safety. Nylon has excellent sound-dampening properties, reducing noise and helping to eliminate buzzing, squealing and rattling.


5. Nylon Coating is Surprisingly Affordable

It’s true: nylon powder coating usually costs more upfront than traditional powder coatings. However, its superior performance and durability make nylon the more cost-effective choice in the long run. Few other coatings can match its outstanding cost-to-performance ratio.

When to Use Ultrasonic Cleaning to Prepare Parts for the Coating Process

Washing is an important step in the process of preparing parts for industrial metal coating. For certain types of parts and materials, ultrasonic cleaning is the safest and most effective pre-coat cleaning method. We’ll explain in brief how ultrasonic cleaning works and to determine when to use ultrasonic cleaning to prepare parts for coating.


When to Use Ultrasonic Cleaning to Prepare Parts for the Coating Process


Parts Washing 101: Why Clean Parts are Important

Washing does more than make the part shine. Parts washing is a mandatory step in the industrial metal coating process.


The performance and longevity of a coating depend greatly on the quality of the surface to which it is applied. Simply put, a coating cannot adhere as well to a part covered in dust, dirt, oil, rust, algae or other contaminants. That is true of PVC coating, poly coating, and all other metal coating technologies.


Neglecting to clean parts before coating them leaves them vulnerable to the very problems that coatings are meant to prevent.


The most common parts washing methods in the industrial metal coating industry are drum washing, hang washing, and ultrasonic cleaning. Drum and hang washing are highly effective, but too rough for delicate parts or sensitive materials.


Ultrasonic cleaning is a far gentler solution for cleaning parts in before the coating process.


How Ultrasonic Cleaning Works


Ultrasonic cleaning uses a process called cavitation to loosen dirt and other contaminating particles.


  1. The operator places the object to be cleaned into an ultrasonic cleaning chamber filled with water or cleaning solution.
  2. The machine generates high-frequency ultrasound waves, agitating the liquid.
  3. Millions of microscopic bubbles form in response to the vibration, covering the object and penetrating any cracks and recesses.
  4. The bubbles force contaminants loose from the surface of the object.
  5. In most cases, the part is clean within 3 and 6 minutes.

The results are impressive. Ultrasonic cleaning can remove everything from ground-in dirt and rust to stubborn oil and grease stains. It can also remove organic contaminants like bacteria, which is why the medical industry uses ultrasonic cleaning for surgical and dental instruments.


It is important to note that ultrasonic cleaning is not the same as sterilization. For medical instruments, sterilization is a separate step in the metal coating process that follows ultrasonic cleaning.


When to Use Ultrasonic Cleaning to Prepare Parts for Coating


Ultrasonic cleaning is an ideal solution for many types of delicate parts. “Delicate” means parts made from sensitive materials like aluminium, or with shapes that are easily damaged: thin or narrow protrusions, holes, machined surfaces, or small details.


There are several reasons why ultrasonic cleaning is a safer pre-coating process for more sensitive components:


  • The cavitation effect of ultrasonic cleaning can remove contaminants to prepare parts for coating without the use of harsh chemicals.
  • Cavitation is gentler than the motion of drum washing or hang washing.
  • Ultrasonic cleaning does not cause parts to bump together or against the side of the cleaning chamber.

Most hard, non-absorbent parts are suitable for ultrasonic cleaning, including parts made of aluminium, metal, glass, ceramic, or hard plastic.

A-Coating vs E-Coating: What’s the Difference?

A-coating and E-coating are two industrial metal coating technologies used to apply a rust and corrosion-proof coating to metal parts. Both are dip-coating processes that see wide use in the automotive and heavy machinery industries as a means of coating large components.



Despite these similarities, there are important differences to consider when selecting the correct industrial metal coating process.


What is A-Coating?

A-coating is a colloquial term for coating with Aquence, a Henkel® specialty coating product. Aquence was previously marketed as Autophoretic coating.


Aquence or A-coating is a waterborne poly coating that bonds to iron on contact. When a part made of ferrous material is dipped in a tank of liquid Aquence, the product bonds to the part with a chemical reaction. Next, manufacturers place the part in an oven to cure the coating.


A-coating has gained recognition in the automotive and heavy industrial manufacturing industries as a reliable metal coating technology. It has unlimited throwing power, and excellent corrosion and scratch resistance.


Aquence is also environmentally sustainable, containing no heavy metals and very few volatile organic compounds (VOCs). Any wastewater resulting from the A-coating process can be treated and disposed of in an environmentally-friendly way.


There are two types of Aquence coating available:

Aquence 866 leaves a matte-like finish and cures at low temperature, enabling manufacturers to coat full assemblies without affecting plastic or rubber bushings.
Aquence 930 is an epoxy acrylic coating with a semi-gloss appearance, ideal as Class B finish or primer coat.

Plastico is the only industrial metal coating company in Canada to offer A-coating in both Aquence 866 and Aquence 930 coatings.


What is E-Coating?

E-coating refers to electrophoretic painting or electrocoating, a metal coating technology developed to apply anti-corrosive coating.


The e-coating process involves immersing the part in a series of dip tanks, first to pre-treat and apply zinc phosphate and then to coat, clean, rinse, and condition it. When the part is dipped into the coating materials, the manufacturer activates an electrical current that passes through the tank using the part as an electrode. This electrical activity causes a layer of resin to adhere to the part, coating all surfaces exposed to the substance.


As with A-coating, a part coated with E-coating must be cured after application.

It is possible to control the thickness of the coating by adjusting the electrical current to the tank. A higher voltage will result in a thicker coating.


Differences Between A-Coating and E-Coating

While these metal coating technologies sound similar, the differences between A-coating and E-coating are significant.


A-coating bonds to metal using a chemical reaction, while E-coating bonds through the application of an electrical current.
A-coating equipment requires fewer dip stations and has a much smaller footprint than E-coating equipment. E-coating involves a lengthy pre-treatment process with multiple washing, cleaning, rinsing and conditioning stations.
Since it uses less equipment, the A-coating process consumes significantly less energy than E-coating.

While durable, E-coating is vulnerable to UV rays. A-coating is a durable poly coating that withstands UV.

Why Use Aquence Metal Coating?

Aquence®, previously branded as Autophoretic® and known also a-coat, is an environmentally-sustainable dip coating made exclusively for parts made of iron. This thin but highly durable rustproof paint is widely used as an industrial metal coating for automotive parts.



Why use Aquence coating? Whether you call it Aquence, Autophoretic or a-coat, the product offers solutions to many common metal coating concerns, including:

  • Coating fully-assembled parts
  • Coating parts with a complex shape
  • Protecting parts from scratches or corrosion
  • Providing a very thin coating (between 0.5 and 1.0mm in thickness)
  • Minimizing environmental impact
  • Coating iron parts while leaving other metal parts untouched


Able to Coat Fully-Assembled Parts

Aquence has the ability to coat entire parts, inside and out, which is a rare feat for an industrial rustproof paint. The coating uses an organic polymeric emulsion to chemically bond to the surface of iron. This property makes it possible to produce a uniform coating parts that are already partially or fully-assembled.


Superior Throwing/Wetting Power

The consistency and properties of Aquence coating make it ideal for coating iron parts that have an odd or complex shape. Aquence has nearly unlimited throwing or wetting power, providing uniform coverage even in those hard-to-reach areas other coatings leave dry. And since it bonds with a chemical reaction, you can trust Aquence to coat every iron surface it touches.


Durable, Scratch-Proof and Corrosion-Resistant

Aquence uses a chemical reaction to forge a highly durable bond to clean iron surfaces. Though it goes on thin, Aquence rustproof coating is remarkably durable, corrosion-resistant, and scratch-proof. Additionally, Aquence has a Neutral Salt Spray (NSS) rating of 1000 hours. This toughness is part of what makes Aquence an ideal choice for demanding applications like vehicle frames and chassis components.


Thin Coating

For parts that will operate with minimal clearance, Aquence can produce an extremely thin coating of between 0.5 and 1.0mm in thickness. Though it goes on no thicker than paint, Aquence coating still provides iron with reliable protection from scratches, salt, and corrosion.



More and more manufacturers have ecological impact on their radar, fuelling an increasing demand for industrial metal coatings that are safe and environmentally sustainable. Aquence 866 is a water-based coating that is free from heavy metals and volatile organic compounds (VOCs); Aquence 930, an epoxy-acrylic urethane coating, contains no heavy metals and a low level of VOCs. Both coatings provide a durable, rustproof surface with minimal impact on the environment.


Bonds Only to Iron

Need to coat an iron part while leaving the rest of the workpiece dry? Aquence 866 is formulated only to bond to iron. The low curing temperature of 220-240° means you can coat iron parts in assemblies that also contain rubber, plastic or Teflon pieces without causing any damage or movement restrictions.


Aquence Coating in Ontario

Plastico remains one of few Aquence coating suppliers in Ontario, and the only Canadian commercial coater to offer metal coating services using both Aquence 866 and Aquence 930. Contact us for inquiries about metal coating services in Ontario.

Choosing a Coating: Nylon Coating vs. Polyester Coating

Powder coatings protect metal parts from weather, corrosion, and whatever else you throw at it. Two of the most popular powder coating options are nylon and polyester coatings, each of which have broad applications in a variety of industries. These are a few of the main considerations when choosing between nylon coating vs. polyester plastic coating.


Nylon Coating Powder


Heat Resistance

An important difference between nylon coating and polyester coating is how each material reacts to heat. Nylon is a thermoplastic, while polyester is a thermosetting plastic. While the two sound similar, the distinction is important if the part to be coated will be exposed extreme temperatures.


Thermosetting plastics start out as separate polymer compounds. When subjected to sufficiently high temperatures, these polymers react to form a strong chemical bond. This bond is irreversible, and the plastic coating will remain solid even under extreme heat. In other words, poly coating is a one-way street: once it hardens, it is not possible to reform or recycle it.


Thermoplastics like nylon coating are different. Although thermoplastic compounds also melt under high heat, there is no chemical reaction involved, so the process is reversible. You can re-melt and re-form nylon coating as many times as you require! It is even possible to recycle nylon and thermoplastic coatings.


To borrow a metaphor, where thermoplastics are akin to butter, thermosetting plastics are more like bread. A baker can repeatedly melt and cool the same stick of butter, but they cannot break a loaf of bread back down into its ingredients!


For this reason, poly coatings are more heat-resistant than nylon coatings, but nylon coatings have advantages in other high-performance applications.



Depending on the application, both polyester and nylon plastic coatings can protect the surface of metal parts from abrasions. Polyester coatings tend be flexible, with impressive impact and chemical resistance. However, this is an area where nylon coating wins out overall.


Once applied to a part, nylon coating flows out to form a continuous, protective bond to the surface. This creates a powerful, resilient barrier against salt, UV rays, and all manner of wear-and-tear. Nylon coating remains durable even in thin applications, making it ideal for tight tolerances. Arkema’s ® Nylon 11 coating, one of our products of choice at Plastico, is specially designed to give metal parts a longer shelf life.


A secondary advantage of nylon coating is its low friction coefficient. This gives it an ability to cut noise and vibrations from the parts it covers, contributing to a safer work environment and helping to prolong the life of the machinery.



Manufacturers are increasingly becoming mindful of their impact on the environment. For those who are looking to incorporate more sustainable practices, nylon offers a renewable and eco-friendly powder coating solution.


Nylon coating is derived from castor beans, the product of a perennial plant called the Ricinus or castor oil plant. In addition to being recyclable, nylon coating carries almost no carbon footprint! Choosing nylon coating signals to customers that you care about your impact.


Nylon vs. Polyester Coating

Your choice of powder coating will depend on the part’s application and the performance you desire from the coating. Here at Plastico, we are confident in the superior performance of nylon coating, but we are happy to recommend powder coaters who specialize in poly coating as well.

5 Reasons Plastisol is Perfect for Playground Equipment

The playground is more than a place to play. It’s where kids first learn to make friends, take risks, and let loose their imaginations. Plastisol, one of the most versatile metal coating technologies, helps to ensure that jungle gyms are as safe as they are fun. Here are a few of the reasons why Plastisol is the perfect industrial metal coating for playground equipment of all shapes and sizes.


Plastisol Playground Coating


1. Impressive Durability


Playground equipment takes a beating. It requires metal coating technologies that can withstand years of stomping, kicking, scraping, and whatever else kids can throw at it. Plastisol plastic coating holds up to this barrage while being safe for children to explore.


2. Colour Customization


While we typically work with black and white here at Plastico, it’s possible to dye plastic coatings just about any colour of the rainbow. This customization lets you build a playground that matches the surrounding neighbourhood and invokes the imagination of all those who see it.


3. Weather-Resistance


We experience the full spectrum of nasty weather here in Canada, from wicked windstorms to massive blizzards. This, combined with constant use by curious kids, puts a lot of strain on outdoor playground equipment.


Fortunately, Plastisol is made to handle the worst of our Canadian weather. The coating provides a barrier against rust and corrosion for longer than a coat of paint.


4. Cleanliness


Public parks are a haven for families who are looking to enjoy the outdoors. Unfortunately, parks can also be a haven for vandals. Graffiti can be an expensive (and annoying) problem, and playground equipment is no stranger to the spray paint’s wrath.


Plastic coating can’t solve this problem, but it can help to reduce the cost. It is possible to remove graffiti from plastic-coated playground equipment, eliminating the need to re-paint whenever a vandal chooses it as a canvas.


5. Cost-Effectiveness


Like all outdoor fixtures, playground equipment requires ongoing maintenance to look and perform at its best. Maintenance can be a significant expense for school boards and municipalities. It’s also an inconvenience to its users; no child wants to encounter a barrier and a “Wet Paint” sign when they go to the park.


No coating lasts forever. Plastisol is no exception. However, its superior durability and resistance to the elements will reduce the cost of maintaining the metal components of playground equipment compared to painted or bare parts.


Our Experience Coating Playground Equipment


Plastico first stepped into the arena of playground equipment back in 2016 when we partnered with a local outdoor recreation equipment company. Together, we worked to build a Plastisol coating line that could handle their large products. Now, we’re responsible for processing their entire inventory of stairs, bases, and other metal components for playground equipment. We’re thrilled to play a part in bringing safe, fun playgrounds to school boards and cities across North America!


Wondering what else we can do? Plastico is an industry leader for industrial metal coating, and we’re ready to answer any questions you may have about our services. Contact us today!

Which Industrial Coatings are Considered Food Grade in Ontario?

Industrial coatings considered food grade in Ontario

Nylon powder coatings are as diverse as the many industries that use them. One often-overlooked application is that of food production and processing. From the farm to the dinner table, powder coatings help to ensure our food is safe to consume.

Of course, not all coatings are suitable for this purpose. Food processing equipment and containers must meet certain standards to be considered food grade in Ontario.


Specialized food grade industrial coatings are often necessary for both the longevity of part and the safety of the food it touches. The right choice coating can make the equipment easier to clean and sanitize. However, it must also be non-toxic, non-absorbent, and free from defects (like cracks or crevices) that could harbour bacteria.


Which Industrial Coatings Are Considered Food Grade in Ontario?

In Canada, Health Canada and the Canadian Food Inspection Agency (CFIA) set policies and standards to ensure a safe food supply, including the safety of the equipment we use to process food and the materials we use to transport it. The American equivalent, the Food and Drug Administration (FDA), oversees this area in the United States.

The choice of food grade powder coating for a part will depend on the manufacturing process. Parts that will be placed in an oven will have to withstand high temperatures; parts that will be submerged in liquid must have a high resistance to corrosion. Non-stick coatings with a low friction coefficient are often sought in the food processing industry as well.

The type of food ingredient in question may also play a role in the decision. For example, certain materials are more susceptible to corrosion on exposure to acidic foods like pickles or tomatoes.

The number of industrial coatings considered food grade in Ontario is too numerous to list. Below are some of the most common categories of food grade powder coatings in use:


  • Polytetrafluoroethylene coating (PTFE): A thin, non-stick coating that stands up to high temperatures. It does not absorb liquid and has a low friction coefficient. Non-stick cookware and bakeware often use PTFE coating.


  • Fluorinated ethylene propylene (FEP): This food grade coating option is flexible and highly resistant to chemicals but lacks the high-temperature resistance of PTFE. Like PTFE, it is non-absorbent.


  • Antimicrobial coatings: A wide variety of food grade industrial coatings come with antimicrobial properties, which reduce the spread of bacteria and food-borne illnesses. Some contain an active ingredient that kills bacteria, while others resist them passively by preventing microbes from sticking to the surface of the part.


  • Rislan Nylon 11: This durable and versatile polymer coating boasts a low friction coefficient that makes it easy to clean. The main ingredient is Castor beans, which makes Nylon 11 100% renewable and environmentally friendly.

Here at Plastico, we’ve used Nylon 11 to coat everything from fryer baskets to pot handles to cutlery, food trays, and even seafood traps. While it doesn’t taste quite as good as it looks, it does qualify as food grade!

5 Ways to Prevent Corrosion of Metal Parts

prevent corrosion metal parts


No metal is completely safe from the threat of corrosion. But it is possible to slow, manage, or stop corrosion before it causes a problem.


There are practical ways to prevent corrosion in metal parts. Engineers can incorporate corrosion control into the design process. Manufacturers can apply protective corrosion barriers. Finally, the people who use the part can take preventative steps to prolong its life.


What is Corrosion?


Corrosion occurs when a metal reacts with an oxidizing agent in its environment. This chemical reaction can cause the metal to degrade over time, tarnishing its appearance and compromising its structural integrity.


Each type of metal has different electrochemical properties. These properties determine the types of corrosion the part is vulnerable to. For example, iron tools are prone to rust from long-term exposure to moisture, while a copper roof will tarnish under the effects of the weather. While some metals stand up to corrosion better than others (depending on the environment), none are free from every type of corrosion.


There is no one-size-fits-all solution to prevent corrosion of metal parts. With so many types of metal and thousands of possible applications, manufacturers must use various methods to prevent and control corrosion in different metals.


Ways to Prevent Corrosion of Metal Parts


Preventing corrosion in metal parts takes consideration at all stages in the process, from design and manufacturing to finishing and maintenance.


1. Design

Corrosion control begins at the engineering stage. If the part is for use in an environment where it is susceptible to corrosion, manufacturers should design the part with that in mind.


For example, parts exposed to the elements should allow water and debris to drain off instead of collecting on the surface. To reduce crevice corrosion, designers should eliminate narrow gaps that allow air or fluid to enter and become stagnant. For corrosive environments, such as in saltwater, it may be wise to engineer for a degree of corrosion allowance.


2. Protective Coating

Coatings can provide a layer of protection against corrosion by acting as a physical barrier between the metal parts and oxidizing elements in the environment. One common method is galvanization, in which manufacturers coat the part with a thin layer of zinc.


Powder coatings are another effective way to prevent corrosion in metal parts. With proper application, a powder coating can seal the surface of the part away from the environment to guard against corrosion.


3. Environmental Control

Many environmental factors impact the likelihood of corrosion. It helps to keep metal parts in a clean, dry place when not in use. If you intend to store them for a long time, consider using methods to control the level of sulfur, chloride, or oxygen in the surrounding environment.


Galvanic corrosion occurs when metal parts with two different electrode potentials are in contact along with an electrolyte like saltwater. This causes the metal with higher electrode activity to corrode at the point of contact. One can prevent galvanic corrosion by storing these parts separately. This effect can also work as an anti-corrosion measure, as explained below.


4. Cathodic Protection

It is possible to prevent corrosion by applying an opposing electrical current to the metal’s surface. One method of cathodic protection is an impressed current, using an outside course of electrical current to overpower a corrosive current in the part.


A less-complex method of cathodic corrosion protection is the use of a sacrificial anode. This involves attaching a small, reactive metal to the part you wish to protect. Metal ions will flow from the reactive metal to the less active part, reducing corrosion at the expense of the smaller piece.


5. Maintenance

Protective coatings, environmental control, and cathodic protection are effective ways of preventing corrosion in metal parts. However, these measures are nothing without ongoing maintenance and monitoring. Coatings can wear over time; even small nicks and scratches can lead to corrosion. Be sure to keep parts clean and apply additional protection as necessary.
