Solution type polyamide type epoxy curing agent KINGMIDE 305-70 curing agent is a standard reactive polyamide intended for use in curing of epoxy resin. KINGMIDE 305-70 is cut to 70 percent solids by weight in xylene/ isobutanol. Whem cured with ac high molecule weight of epoxy resin. It is provides cured films with such high orders desired at actual application field as good flexibility, simultaneously with good water resistance and good alkali resistance. KINGMIDE 305-70 is thus desired for heavy duty primer coatings application of anti corrosion resistance. Viscosity ( Gardner Holdt/25C degree ) - W~ Z.
