AGGREGATION-PREVENTIVE AQUEOUS-DISPERSION SLURRY COATING MATERIAL AND PROCESS FOR PRODUCING THE SAME

WIPO Patent Application WO/2006/118233

A1

An aqueous-dispersion slurry coating material excellent in storage stability and coating film smoothness. The aqueous-dispersion slurry coating material is characterized in that it comprises an aqueous medium and, contained therein, resin particles (A) comprising a first resin (a) and resin particles (B) comprising a second resin (b) and that the value of [volume-average particle diameter (DA) of resin particles (A)]/[volume-average particle diameter (DB) of resin particles (B)] is 0.003-0.3. In the aqueous-dispersion slurry coating material, DA is preferably 0.001-3 µm, DB is preferably 0.3-10 µm, the resin (a) preferably has a Tg of 0-100°C, and the resin (b) preferably has a Tg of -50 to 50°C. The coating material preferably further contains a surfactant and a hardener. The resin (a) and resin (b) each preferably comprises at least one resin selected from the group consisting of a polyurethane resin, epoxy resin, vinyl resin, and polyester resin.
