LOPON® DA 401 is a highly effective dispersing agent formulated with middle-molecular-weight potassium polyacrylate. It is specifically designed for use in silicate emulsion paints. By utilizing potassium as the cation, it prevents the introduction of additional ions into the system, thus suppressing efflorescence during the drying process that can occur through the formation of sodium carbonate. LOPON® DA 401 achieves excellent deflocculation results when incorporated into highly filled systems containing inorganic pigments such as titanium dioxide, calcium carbonate, and mica. The product possesses high alkaline stability and exhibits strong compatibility with polyphosphates like POLYRON® N, offering very good storage stability.
