Application: AS881 is a precipitated sodium aluminum silicate with a high level of whiteness and reduced coarse particles, which is highly recommended for partial substitution of white pigments in emulsion paints, as a matting agent for silk glossy paint systems and as a filler in printing inks.
AS881 is also used as a special-purpose filler for mechanical graphic papers, as an extender for titanium dioxide in papermaking, and as a white pigment for coated papers. It has beneficial effects on reducing possible ink bleeding, the printability, smoothness and friction coefficient of the paper, as well as enhancing pitch control.
Usual Packing: 12.5kg net or 25kg net paper bag or polywoven bag.
