Matt Hardener For Powder Coating

Description

1, Matt Hardener is a composed salt of cyclic-amidine and multi-acid. It utilizes the two different reaction rates of group in molecular structure, and during the curing process, it generates nonuniform shrinkage then forms the matt surface. It has both gloss decreasing and curing functions.

2, Powder coating mainly divide into three types: Polyester/Epoxy Powder Coating (indoor product), polyester/TGIC powder coating (outdoor product), Epoxy powder coating (indoor product). TGIC is listed as hazardous material; it may be replaced by HAA in the future. The benefits of powder coating that it is environmentally friendly. There are no solvents in paints, and thus no harmful air pollution. Overspray can be air vacuumed and reused, thus reducing the amount of wasted produced as well as saving cost.
