Disp 800 Sodium polyacrylate ADD APT Colloidal stabilizers / Dispersing agents >> Sodium Polyacrylate Polyvinyl Chloride (PVC) ADHESIVE Soluble in water ADD APTâ DISP 800 and DISP 900 are excellent solvent-free Dispersants for (mineral) pigments and fillers. They enable a high pigment loading at low viscosity. ADD APTâ DISP 800 and 900 are low- and narrow molecular weight polyacrylate dispersants having either a sodium - or a ammonium cation.ADD APT® DISP 800 or DISP 900 are 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 APTâ DISP 800 or 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 both DISP 800 and DISP 900 guarantees a high effectiveness in dispersing properties. pH application range 4 - 13 No R- S- phrases Solvent-free polyacrylate dispersant having sodium cation. Suitable for pigments(mineral) and fillers. Possesses low and narrow molecular weight distribution that ensures highly effective dispersing properties recommended for use in PVC (15 - 30%) formulations.
