Description

Powder coatings are formulated from plastic resins, fillers, pigments, binders, cross-linkers, and flow agents. Powder-coating manufacturers achieve specific formulations by varying ingredients and their proportions, which determine the powder’s and final coating’s properties once the coating is applied to the substrate. Powder-coating resins are dry, plastic resins. The two major powder coating types are thermoplastic powders and thermosetting powders. Industry has made dramatic advances in developing polyester and acrylic resin systems with excellent long-term weatherability to meet extended manufacturer warranties.
