BYK® -151

BYK® -151 by BYK is a solution of an alkylolammonium salt of a polyfunctional polymer with anionic character. Acts as a wetting- and dispersing agent. It provides good storage stability for the system. It stabilizes pigments through electrostatic repulsion. For optimum performance, these additives must be incorporated into the millbase before addition of pigments. BYK® -151 reduces viscosity and improves wetting of pigments and fillers. Used in dispersion adhesives. Its recommended levels based upon titanium dioxide, filler and inorganic pigments are 1.5 - 2%, 0.5 – 1%, 2 - 10% respectively.
