ABSTRACT:
A thermosetting powder resin based water-slurry coating composition prepared by dispersing water insoluble thermosetting resin particles and an adduct of a structurally symmetrical diol having a molecular weight of from 90 to 300 with ethylene oxide or propylene oxide, or a mixture thereof in an aqueous medium. The composition provides improvements in the anti-sedimentation properties and redispersibility of particles, and consequently in the extended storage stability and application performance thereof. The composition is applied to form a film with excellent smoothness, gloss, water resistance, moisture resistance, corrosion resistance, etc., without developing any pinholing and cratering by solvent popping, and checking on film formation by heating.
