摘要
PROBLEM TO BE SOLVED: To prepare a coating material for precoated steel plates using a low priced polyacrylic resin and giving better wheatherability and stain resistance, and to provide a precoated steel plate and panels for roof walls or the like using the same, and to provide a method for producing the precoated steel plate. ;SOLUTION: This coating material is prepared by including both (A) an acrylic polyol-based copolymer obtained from a polymerizable monomer for stabilization to ultraviolet light, a polymerizable monomer having a cycloalkyl group and a polymerizable monomer having a hydroxyl group as essential monomers and (B) a fluororesin powder containing polytetrafluoroethylene. The coating material is applied to at least one side of steel plate in a coating thickness of 1-25 m and is baked at the plate temperature of 150C and 320C to produce precoated steel plate excellent in weather resistance and stain resistance.;COPYRIGHT: (C)1999,JPO
