Pigment Dispersion: Wetting & Dispersing Agents for Coatings
Excellent wetting and dispersion performance in mill-bases for dispersion paints can be achieved using a combination of sodium- or ammonium-polycarboxylate and polymeric non-ionic surfactant additive. A main non-ionic additive is alkyl phenol ethoxylate (APE) and more precisely nonyl phenol ethoxylate, NP 10 (ethylene glycol chain of 10 units). ...
