ADD APT Disp 900 Ammonium polyacrylate ADD APT Dispersing agents >> Surfactants-like >> Sodium polyacrylates / Polyacrylic acids Vinyl Soluble in water ADD APT DISP 900 is excellent solvent-free Dispersants for (mineral) pigments and fillers. They enable a high pigment loading at low viscosity. ADD APT DISP 800 is low- and narrow molecular weight polyacrylate dispersants having a ammonium cation. Paint industry Printing Ink industry ADD APT ® DISP 900 is recommended for use in formulations with low- medium PVC (15 - 30 %) The gloss of emulsion paint and lacquers is not influenced by the addition of ADD APT DISP 900. Both products show high glycol compatibility. ADD APT ® DISP 900 is recommended for applications where sodium ions are undesired. The very narrow molecular weight distribution of DISP 900 guarantees a high effectiveness in dispersing properties. Low- and narrow molecular weight polyacrylate having a ammonium cation. Used as a very good solvent-free dispersant for (mineral) pigments and fillers in paint and printing ink industries. Allows high pigment loading at low viscosity. Recommended for use in formulations with low- medium PVC. Does not affect gloss of emulsion paint and lacquers. Offers high glycol compatibility.
