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 drying groups. Optionally, the coating composition comprises in addition to the above-mentioned dispersions an emulsion of an alkyd resin. The coating composition can be used as a translucent or opaque primer or topcoat or as a clearcoat in decorative applications.
