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.
