DISPERBYK® -199

DISPERBYK® -199 by BYK is a solution of a copolymer with pigment affinic groups. Acts as polymeric wetting and dispersing agent. It is APEO- and amine-free. DISPERBYK® -199 is a cost-effective alternative to commonly used dispersants (e.g. Na⁺ and NH₄⁺ salted polyacrylic acids). It reduces viscosity, subsequently, leveling is improved and higher pigment load is possible. This high molecular weight additive is used in aqueous systems for deflocculation and stabilization of inorganic and organic pigments. Its recommended levels are 10 – 30% inorganic pigments, 2.5 - 7.5% titanium dioxide, 37.5 – 100% organic pigments and 75 – 125% carbon blacks based upon pigment.
