中文UNIQ®SPERSE 650 U is a wetting and dispersing additive based on new generation chemistry technology for solvent-, water based and solvent free applications. The dispersant is especially developed for the grinding of inorganic pigments, extender pigments and matting agents. Especially in water based systems it will prevent sedimentation of the inorganic pigments what can help you to eliminate or reduce the use of a rheology control agent.
