Thermosetting powder coating
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
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
Polyester powder coating is one type of thermosetting powder
Thermosetting powder coatings are available in three basic types,
each offering different performance attributes.
1. Pure Epoxy Powder Coating. Epoxy for the best corrosion protection.
2. Pure Polyester Powder Coating. Polyester for the highest exterior stability and performance.
3. Epoxy-Polyester Powder Coating(Hybrid). Hybrid(s) typically offer the best chemical and solvent resistance.
Polyester powder coating
Thermoset polyester powders are produced on the basis of high grade
polyester resin specialized for powder coating production.
The products may provide coating film with toughness and
durability, high gloss, good weatherability, especially outdoor
exposure durability, heat resistance and excellent anticorrosive
and anti-blooming properties.
