powdercoating types

Types of Powder Coatings

There are two kinds of powder coatings: thermoset and thermoplastic powder coatings. Under each, we have different types. Manufacturers and buyers usually examine the potential coating complexity and the overall cost before they can decide which type is appropriate for their application. There is also another category known as the new technologies.

Thermoplastics are synthetic materials which may be formed several times. High temperatures may melt thermoplastics, and this is beneficial in recycling as well as forming, though not ideal for situations that may be exposed to intense heating. Thermoplastics used as powder coatings are usually chemical-resistant and wear-resistant.

Thermosets are applied like the thermoplastic powders. However, unlike thermoplastic, they go through a series of chemical, cross-linking reaction which is not reversible once baked. The following are various types of powder coating supplies.


Polyvinyl chloride is a sleek, pliable and durable powder coating. Like nylon, they are also approved for food contact and may be used in many similar applications. PVC is also suitable for insulating electrical lines and work just as well for chain link fence coating.PVC


This is an extremely impact-resistant and durable powder coat. It offers great protection against solvents and chemicals and is approved for food contact. The parts that are covered with this type of powder coat include dishwashers and food handling baskets. It also has a very low friction coefficient, which makes it useful for coating conveyor equipment and gears.


These are very resistant to chemicals and abrasives. They offer excellent adhesion and smooth surface properties. These benefits make polyolefin coating useful for lab components, which need regular cleaning.


These coatings look great and are also resistant to abrasions. They are useful for outdoor furniture and exposed auto parts like the strut spring and the leaf. They come in diverse colors. Some are certified for building exteriors because they shield elements and maintain their color.


Epoxy coatings are electrically insulative and hard. They are, however, brittle if exposed to UV light and can become dull and chalk over time. This makes them suitable for use as pipe coatings, indoors or buried underground.


Unlike the epoxy based resins, they do well in sunlight and can blend over surfaces, hence leaving wet-looking, high gloss finish that may be pigmented or clear. They lack durability because of their brittle hardness but are extensively used in some automotive parts like the wheels and exposed parts of the engine.

New technologies

newtechnologiesIt is not possible for powder coating to coat plastic pieces because of the high heat needed during the curing process. Some developments are creating new powders and resins using UV light for curing. This type of curing can be achieved in less than two minutes under temperatures lower than 22 degrees Fahrenheit. This technology is still new and has not been advanced.…
