Powder Coating is the application of dry powder to metal surfaces which is then fused together when heated. The solid particles of powder, comprising resins, pigments, and fillers are electrostatically charged in a spray gun and carried by low velocity air to the surface of the part to be coated.
The electrostatic charge holds the powder particles in place while the part is cured in an oven to 200ºC to produce a hardened durable surface. Powder coating provides a finish tougher and more durable than conventional paint. Powder coatings resist cracking and peeling and are extremely abrasion, corrosion, and chemical resistant, but are not a rust inhibitor. For this reason, it is critical that the substrate receives appropriate corrosion protection, chromate for aluminium product, and zinc rich primer for steel and cast iron products.
- Cleaning of material ensuring the surface is free of any oils, dirt, grease, and foreign matter. This can include abrasive blasting and or solvent cleaning.
- Pre-treatment during which the product is treated with chemicals to further clean, protect, and prepare the substrate with a surface that enables good adhesion of the powder coating.
- Rinsing and drying.
- Powder application with an electrostatic gun.
- Curing in an oven. The product is heated to a pre-determined metal temperature for a selected period of time after which the product cools and the coating forms a high-quality and durable finished surface.
