Abstract:
A nontoxic anticorrosive pigment composition free from toxic heavy metals comprises a condensed phosphoric acid aluminum salt, typically aluminum dihydrogen tripolyphosphate, and magnesium silicate, typically magnesium hexasilicate. The anticorrosive pigment composition enhances the thermal resistance of paint films when formulated in a coating composition containing a chlorine-containing vinyl polymer such as vinyl chloride-vinylidene chloride copolymer emulsion paints.
