Powder Coating

Powder Coating represents 15% of the total industrial finishing industry. There are two different types of powder used for coating parts – Thermoset and Thermoplastic.

Thermoset Powder

This material used for most of powder coating since it can provide a nice surface layer. The layer not only creates a finished look and provides durability, but it also reacts when baked with other chemical groups in the powder to polymerize harder, which improves the performance properties. After curing thermoset powder, it cannot be melted back into a liquid from further heating.

Thermoplastic Powder

This type does not permanently change during baking, and will remelt if heated. These are the type of coatings you may find on refrigerator shelves or metal benches, for example. Thermoplastic powder coatings provide a functional, flexible, and durable coating to a variety of materials.
