AQUEOUS COATING COMPOSITION COMPRISING A MIXTURE OF POLYURETHANE DISPERSIONS

摘要

The present invention relates to an aqueous coating composition comprising: 5- 95 wt.% of a polyurethane/acrylate hybrid dispersion and 95-5 wt.% of a dispersion of a polyurethane resin with oxidatively dryin g groups. Optionally, the coating composition comprises in addition to the above-mentioned dispersions an emulsion of an alkyd resin. T he coating composition can be used as a translucent or opaque primer or topcoat or as a clearcoat in decorative applications.
