HC68

Salt of cyclic-amidine and multi-acid. It acts as a matting- and curing-agent. It has high melting point, excellent mechanical property and increases extruding temperature. It generates non-uniform shrinkage, forms matt surface and has both gloss decreasing & curing functions. Used in epoxy and epoxy/polyester hybrid powder coatings. The recommended dosage is 8-10% of epoxy resin’s weight in formulation.
