LUBRICATING COATING COMPOSITION FOR STAINLESS STEEL COLD ROLLED STEEL SHEET, AND STAINLESS STEEL COLD ROLLED STEEL SHEET

摘要

PROBLEM TO BE SOLVED: To provide a lubricating coating composition exclusively used for a cold rolled steel sheet in which various properties such as film removability with an alkali, molding processability, powdering resistance, and weldability are improved.;SOLUTION: The coating composition comprises an acrylic resin and a neutralizer. The acrylic resin comprises a copolymer (a) of a methacrylate composed of methacrylic acid and an alcohol, styrene and a monomer having a carboxyl group, a polymer (b) of a polymerizable compound having an ether linkage, and an organic solid wax having a melting point of 60°C or higher as a lubricant, wherein the ratio of the copolymer (a) to the polymer (b) is in the range from 85:15 to 50:50.;COPYRIGHT: (C)2009,JPO&INPIT
