Thermoplastic Powder Coating: Types, Advantages and Uses

Thermoplastic Powder Coating in Australia has been used on a variety of things that we see and use every day since it first appeared in the late 1940s, with commercial products becoming accessible in 1952. In those early products, thermoplastic coatings were employed, and they have been used ever since.

Thermoplastic coatings are made of medium-density plastic and are heated before being sprayed onto metal parts and items as either a decorative or protective coating, and frequently both.

In contrast to thermoset coatings, which will not melt when reheated to help with repairs, the heat melts the coating when it is applied in powder form, enabling it to produce an even, thick finish that makes a durable layer.

Coating With A Thermoplastic Material

The method known as fluidized bed dipping is the most popular approach to applying these Thermoset Powder Coating Systems. Depending on the specific application, the metal components are heated up to between 360 and 400 degrees Celsius before being inserted into a bed of thermoplastic powder.

The fluidized bed coating process involves agitating powder by forcing compressed air over it, giving it the characteristics of a liquid and causing it to melt around the metal item, generating a rather thick layer that covers the whole surface and is 200 microns thick or more.

Since no chemical change occurs as a result of heating and setting, this crucial application feature distinguishes thermoplastics. Therefore, if there is a flaw or damage, the coating may be heated again, melting and flowing to fix the issue.

Due to its inability to reliquefy after setting, regardless of the amount of heat given, thermoset powder coatings make this impossible.

Various Thermoplastic Coating Types

Low-density polymer, PVC, Nylon, polyethene, and thermoplastic polyester are just a few of the substances utilized inThermoset Powder Coating. Each exhibits distinct properties, with a material choice based on the requirements of the application.

The earliest powder coatings were made of polyethene polymers because they had excellent electrical insulation and corrosion resistance.

They are widely utilized in situations where consumers connect with the items regularly, such as handles in subway vehicles for people who are standing up. They are warm to the touch. Polyethene coatings are favoured in lab items because of their simple maintenance capabilities and resistance to corrosive substances.

The Benefits Of Coatings Made Of Thermoplastic

Thermoplastics provide a one-layer solution for even the hardest situations since they can be applied in significantly thicker coats than conventional powder-coating solutions.They are typically seen on handles, staircases, and other areas of contact because they are warm to the touch, retain a soothing effect than the hard-shell coatings, and are more pleasant to engage with.

The thermoplastic powder coatingis also a superb electrical insulator, suitable for a variety of applications. Along with their outstanding waterproof qualities, thermoplastic coatings are frequently used on goods like refrigerator shelves since they render coated objects relatively passive regarding temperature transmission.

Where Are Coatings Made Of Thermoplastic Used?

There are many different types of powder coatings, and you probably come into contact with them daily without even realizing it.

You are likely to find thermoplastic coatings on refrigerator shelves and dish washing baskets throughout the house due to the special qualities that make them incredibly helpful in a variety of applications.
