RESIN COMPOSITION FOR POWDER COATINGS

摘要

There is disclosed a resin composition for powder coatings, which comprises a blend of two acrylic resins being obtained by polymerizing a prescribed amount of monomer component (a-1) represented by formula (I) and a prescribed amount of another monomer component (a-2), respectively, and having different polymerization degrees represented by viscosities at 140.degree.C and a polybasic acid compound in 1.5 to 0.5 equivalent ratio of the glycidyl groups in said acrylic resins to the acid groups in the polybasic acid compound. Formula (I) (see fig. I) wherein R1 and R2 each represent a hydrogen atom or a lower alkyl group. Disclosure described provides a resin composition for powder coatings that can form a coating film having a mat smooth appearance and excellent in flexibility as shown Du Pont impact resistance and the Ericksen test as well as excellent in nail scratch resistance.
