COATING COMPOSITION FOR COATING METAL PLATES

摘要

PURPOSE:To obtain the title composition excellent in processability and staining resistance by adding a small amount of amine-blocked dodecylbenzenesulfonic acid to a specific polyester-melamine resin. CONSTITUTION:The subject composition is composed of (A) 100 pts.wt. of a polyester-melamine resin from a polyester resin of 5 to 40 deg.C glass transition point and 15,000 to 30,000 number-average molecular weight and hexa- methoxymethylol melamine resin at a weight ratio of 75/25 to 55/45 and (B) 1 to 2 pts.wt. of an amine-block product of dodecylbenzenesulfonic acid.
