ANTI-TERRA-250 is a controlled flocculating wetting and dispersing additive suitable for aqueous primers, fillers as well as adhesives and sealants to prevent sedimentation of fillers and inorganic pigments. ANTI-TERRA-250 acts in aqueous systems by controlled flocculating the pigments. This primarily prevents the flooding/floating and sedimentation of the pigments as well as sagging. Thixotropy is enhanced. The controlled flocculating properties may lead to a slight gloss reduction. ANTI-TERRA-250 reduces the viscosity in filled systems and, at the same time, prevents sedimentation and flooding/floating. Thixotropy is enhanced.
