Abstract
Abstract Epoxy ester-modified alkyd resin formulations are provided comprising: (i) from about 70 to 80 wt % soya modified alkyd resin; (ii) from about 4.75 to 10 wt % epoxy ester resin; (iii) from about 4.75 to 10 wt % silicone modified alkyd resin; and (iv) from about 0.5 to 10 wt % compatible solvent. These alkyd resin formulations can be pigmented to provide a wide variety of pigmented, epoxy ester modified, air dry alkyd enamels.
