COATING RESIN COMPOSITION FOR METAL

摘要

PROBLEM TO BE SOLVED: To provide an epoxy resin-based coating resin composition which enables various metallic surfaces to be coated with a coat which exhibits good anticorrosion as well as excellent adhesion, hardness and water resistance.SOLUTION: A coating resin composition for metal is obtained by mixing: an amine urethane-modified epoxy resin (A) obtained by reacting a polyisocyanate (a3) with an amine-modified epoxy resin (A') obtained from a prescribed amine (a1) and an aromatic epoxy resin (a2); and a polysilsesquioxane (B) which is a hydrolysis condensate of a prescribed trifunctional alkoxysilane.
