Title:
アクリル系熱硬化性粉体塗料組成物
Document Type and Number:
Japanese Patent JP4205365
Kind Code:
B2
Abstract:
The acrylic thermosetting powder coating compositions comprise: a glycidyl group-containing acrylic resin (A) which comprises at least one glycidyl copolymer (a) modified with a carboxyl compound (C) and which may contain an unmodified glycidyl copolymer (a), these modified and unmodified glycidyl copolymers (a) having glycidyl groups and/or beta -methyl glycidyl groups; and a polyvalent carboxyl compound (B) as a curing agent component, the above carboxyl compound (C) being at least one compound selected from the group consisting of fatty acids, oxyacids and polyvalent carboxyl compounds. The acrylic thermosetting powder coating compositions can be obtained in enhanced homogeneity by a conventional compounding technique so that they have an improved compatibility particularly with polyesteric thermosetting powder coatings without any deterioration in appearance properties (smoothness, high gloss, etc.), physical properties (hardness, mar/scratch resistance, etc.) and chemical properties (acid resistance, solvent resistance, etc.) of the resultant coating films.
