Detailed Description
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.

Application
1, HF-68 can be applied in epoxy powder system to generate the strong matte effect, terrific leveling performance and stable comprehensive properties. It can be used for pure epoxy and epoxy/polyester hybrid powder systems as a hardener, preparing coatings with super matte surface, excellent mechanical property and good reproducibility characteristic.
2, Pre-mix and Co-extrusion [One-Shot Method]
Advantage
1, One-shot effect:No dry-blending is required.
2, Durability:Very good weathering resistances
3, It has good color stability & mechanical properties, as well as good stability both during processing and storage.
