COATING TRANSFER IMPROVED ACRYL RESIN COMPOSITION FOR BACK SIDE COATING OF THICKNESS FILM PRE-COATED AUTOMOBILE STEEL SHEET AND PAINT COMPOSITION

摘要

PURPOSE: An acrylic resin composition with excellent releasing force is provided to absolutely improve a releasing agent-transition phenomenon which is a weakness of existing silicon releasing agent. CONSTITUTION: An acrylic resin composition consists of 40-70 weight% of an acrylic monomer copolymer. The acrylic monomer copolymer is obtained by mixing 60-90 weight5 of an alkoxy silane group-containing acrylic monomer and 10-40 weight% of an amide group-containing acrylic monomer. The paint composition consists of 15-35 weight% of the acrylic resin composition, 20-40 weight5 of an epoxy resin composition, 30-54 weight% of an organic solvent, and 1-5 weight% of an additive.
