ANTI-TERRA is one of BYKs trade names for wetting and dispersing additives. Wetting and dispersing additives stabilize pigments (inorganic, organic and also effect pigments) and fillers. Wetting agents are surface-active substances and improve the wetting of solids. Dispersing agents prevent particles flocculating by various mechanisms (electrostatic effects, steric effects). Wetting and dispersing additives unite both mechanisms of action in one product, i.e. they are both wetting and stabilizing. ANTI-TERRA are mainly used to support anti-separation and anti-settling properties of formulations.
