HC68 series 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.

Luna-CRYL 700 is a glycidyl functional acrylic resin which can be used as a curing agent for saturated carboxyl polyesters having low acid values (i.e. 33) to produce exterior durable powder coatings with dead matte to low gloss finishes (60° gloss range 0–20).
