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.
