Solution of an alkyl ammonium salt of a polycarboxylic acid. Acts as a high molecular weight dispersing and wetting agent for solvent-borne coating systems. Increases thixotropy. Reduces the sagging tendency. Exhibits no negative influence on the water sensitivity of the paint film. Used for medium to low polar solvent-borne and solvent-free coating systems, general industrial, architectural and protective coatings. Also used as anti-corrosion primers, thereby enhancing the protective properties.
