THERMOSET ACRYLIC RESIN COMPOSITION FOR COATING METALLIC MATERIALS AND STAINLESS STEEL COATED WITH THE COMPOSITION

摘要

A thermoset acrylic resin composition for coating metallic materials, particularly stainless steel, having a superior adhesion thereonto and hence a superior resistance to forming after coated, and a stainless steel piece coated with a coating material comprising the above composition, followed by baking, and having a superior colorability and endurability, are provided, which composition is obtained by radical-copolymerizing (a) an acrylic or methacrylic acid ester having 1-12 C in the ester moiety, in 40-80% by weight, (b) a hydroxyl group- or epoxy group-containing acrylic or methacrylic acid ester, in 20-5% by weight, (c) a vinyl group-containing polysiloxane in 20-0.01% by weight and (d) a vinyl group-containing silane compound in 20-2% by weight, these % by weight being based on the total weight of monomers (a)-(d).
