Thermosetting powder coating is suitable for surface coating and decoration of metal (steel or aluminum) items, it is applied to the part or component by electrostatic spraying equipment. In a subsequent curing process, the powder coating is melted and chemically cross-linked at substrate temperatures of 150°C to 200°C.
The raw materials of powder coating are resins, pigments, fillers, harderner ect. Compared with liquid paint, powder coating is environmental friendly and can reduce costs. Powder coating can form a harder finish than conventional paint and can be applied more efficient.
Powder coatings are available in three basic types, each offering different performance attributes.
1.Pure Epoxy Powder Coating
2.Pure Polyester Powder Coating
3.Epoxy-Polyester Powder Coating(Hybrid)
What type of powder coating should I choose?
Epoxy for the best corrosion protection. Polyester for the highest exterior stability and performance. Hybrid(s) typically offer the best chemical and solvent resistance.
