Silicates

SIPERNAT^® 820 A

A 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.

SIPERNAT^® 820 A is also used as a special-purpose filler for mechanical graphics 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.

SIPERNAT^® 880

This calcium silicate is used as a flow and anticaking agent in many applications. It can be used as a carrier for acid sensitive active ingredients in plant protection requiring a slightly alkaline pH-value. In addition, SIPERNAT^® 880 is an auxiliary in polychloroprene adhesives.

SIPERNAT^® 44 MS

As a synthetic sodium aluminum silicate of high purity, SIPERNAT^® 44 MS is used as an antiblocking agent in polyolefins for excellent haze- and CoF values at high masterbatch loadings.
