| abstract |
The invention relates to environmentally friendly water dispersion compositions having favorable rheological properties, enhanced chemical resistance and mechanical strength and good adhesion to various types of substrates (metal, wood, concrete, plastic, etc.) and a wide range of suitable application methods (pneumatic). airless spray, brush, roller, etc.). The composition contains as a film-forming mixture of aqueous dispersions of aromatic or aliphatic polyurethane acrylate and a polymer different from polyurethane acrylate, with N-alkyl pyrrolidone and, if necessary, with other additives. Based on the composition according to the invention, for example, aqueous polyurethane acrylate enamels and varnishes can be obtained. |
