MACRI CHEMICALS MATT HARDENER HC68 is a complex salt of cyclic, multi-acid amidine. It uses the two different reaction rates of the groups in the molecular structure and, during the catalysis process, first generates a non-uniform "wrinkling" and then creates an opaque surface. It has the function of reducing gloss and acts as a hardener. 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.
