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.

QA_Luna-vin Lunavin VAGH-W is widely used for coatings, maintenance coatings, marine paint, wood surface paint, paper coatings, metal decorative paint, container paint, aluminum plated film paint, PVC/steel adhesive and tape adhesive. Luna-vin VAGH-W is a hydroxyl modified Vinyl-chloride and vinyl acetate copolymer. It has good compatibility with alkyd resin, PU elastomer, epoxy polymer, melamine resin, and urea. It can improve coating properties, strengthen coating adhesion, hardness, flexibility, and chemical resistance. It can also provide crosslinking reaction for thermo-setting coating systems, to improve water resistance and chemical resistance.
