Germany dispersant BYK-AT203 dispersant BYK-AT203 ANTI-TERRA? -203 Wetting and dispersing additive used to improve pigment wetting and stabilize the pigment dispersion. The additive is a controllable flocculant, particularly applicable to the primer and the undercoat layer. Thixotropy, to prevent pigment floating color, blur and settlement, as well as to reduce the coating sagging. The additive can be used to gel organophilic bentonite, in order to improve the fluidity, the workability and the storage stability of the bentonite slurry preparation. The additives suitable for medium to low-polarity solvent-based and solvent-free coating systems. In addition, it does not adversely affect the water sensitivity of the coating film. In many cases, used for anti-corrosion primer, can improve its protection.
