ASP 400 P

ASP 400P is a highly pulverized hydrous aluminum silicate powder with a median particle size of 3.5 microns and specific gravity of 2.58. It has low oil absorption of 33% and is chemically inert. ASP 400P kaolin is widely used in industrial applications where its coarse particle size and controlled exotherm are beneficial. Its low resin demand and shrinkage make it well-suited for glass-reinforced composites, helping to provide good glass carrying ability and craze resistance. ASP 400P is especially effective in BMC/SMC and pultrusion profiles due to its ability to improve enamel holdout. Applications include water-borne and solvent-borne exterior primers and flats, as well as stains, thanks to its low brightness and higher loading capacity in paints.
