Polymer surfactant can be used as pigment dispersant

Polymer surfactants have a good dispersion effect on pigments (fillers) in water and solvents. Some people call it a super-dispersant. It consists of two parts, one part is a polar group such as one NR2, one NR3, one COOH , A S03H, polyamines, polyols and polyethers, etc. These polar groups are tightly adsorbed on the surface of the pigment through ionic bonds, hydrogen bonds and van der Waals forces to prevent desorption; the other part is the solvation chain and dispersion The medium has good compatibility, which can greatly reduce the interfacial tension between the pigment particles and the dispersion medium, and can form a space barrier on the surface of the pigment to maintain the stability of the dispersion system. In order to improve vehicle speed and save energy, high-solids coatings are used, usually using polymer surfactant dispersants, such as sodium polyacrylate solution (trade names are Dispex N-40, Polysah S, SP61, DC-854) Sodium polymethacrylate and its derivatives, disodium salt of maleic anhydride diisobutylene copolymer, alkylphenol polyoxyethylene ether (OP type product), fatty alcohol polyoxyethylene ether (OS type), etc.
