Air drying coatings having long term water repellency

摘要

An air drying coating adapted to deposit coatings possessing long term water repellency is disclosed in which a high viscosity unsaturated hydroxy functional alkyd resin is combined with from 13-63 parts by weight of dispersed particles of granulated wax per 100 parts of the alkyd resin, the solvent being mineral spirits which cannot itself dissolve the large amount of wax needed, and the wax being a paraffin wax having an average melting point in the range of 50 DEG C.-70 DEG C., preferably 55 DEG C.-65 DEG C.
