COMPOSITION PULVERULENTE REDISPERSABLE DANS L'EAU DE POLYMERES FILMOGENES
摘要:
Water-redispersible powdered compositions including a powder of at least one water-insoluble film-forming polymer prepared from at least one ethylenically unsaturated monomer, at least one non-ionic surfactant selected from polyoxyalkylene derivatives, and at least one water-soluble compound selected from polyelectrolytes belonging to the weak polyacid family, are disclosed.
