What
is Powder Coating?
Process
The powder coating process uses a solvent free dry mix of plastic resins, pigments and fillers that melt and fuse together when heated. The solid particles of coating are electrostatically charged in a spray gun and carried by low velocity air to the surface of the piece to be coated. The electrostatic charge holds the powder particles in place while the part is cured in a 400 degree oven. The heat of the oven causes a chemical reaction to occur and the powder to cure, creating a highly durable finish. Any metal object that can hold an electrostatic charge and withstand the heat of the curing process can be powder coated.

Powder Coatings resist cracking and peeling and are extremely abrasion,corrosion and chemical resistant. The performance characteristics of powder coating match or exceed the characteristics achieved from conventional solvent-based coatings.
Environment
Powder coating is an environmentally friendly process unlike solvent-based
wet paint systems. With EPA regulations growing ever stricter, powder
coating is fast becoming the technology of choice. Since the Powder coating
process does not use solvents in any way, VOC emission problems are eliminated.
