ABSTRACT:
A dispersion composition and a method for coating the surface of steel casting dies for molten metals are described. The dispersion composition comprises boron nitride powder dispersed in a peroxide-modified aqueous dispersion of a water-dispersible film-forming polymer. The coating composition provides thermal insulation to the mold surface, thereby minimizing premature solidification of the cast metal.
