Powder Coating Chemicals
- Powder coating involves the application of dry, free-flowing thermoplastic or thermoset powder material onto a surface, typically metal, and curing it under heat to form a hard, durable finish. The performance and aesthetics of a powder-coated finish largely depend on the powder coating chemicals used. These chemicals can be broadly categorized into formulation components and pretreatment chemicals.
