Greesol DP1050 is a waterborne acrylate block polymer dispersant that polymerized by the controllable free radical technology. By a special reaction process, it has very narrow molecular weight span and specific block Sequence, which make the dispersant can be quickly adsorbed on the surfaces of pigment particles. It performs well for the dispersion of pigments in the waterborne coating systems, especially for carbon black. It has high pigment dispersion stability and good compatibility with various kinds of waterborne resins. Greesol DP1050 is an ideal dispersant for general resin-free color pastes.
