    摘要: There is disclosed a resin composition for powder coatings, which comprises a blend of two acrylic resins being obtained by polymerizing a proscribed 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°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.
    wherein R 1 and R 2 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.

    摘要: A composition for thermosetting powder coating, which comprises

    (a) an acrylic copolymer of high softening point having an epoxy equivalent of 250-1,000 g/eq and a softening point of 90-160 o C,
    (b) an acrylic copolymer of low softening point having an epoxy equivalent of 200-600 g/eq and a softening point of 30-70 o C,
    (c) a polycarboxylic acid, and
    (d) optionally, a phosphoric acid ester compound and/or a phosphorous acid ester compound,
    and wherein the difference in softening point between (a) and (b) is 60-120 o C, the weight ratio of (a)/(b) is 95/5 to 60/40, and the equivalent ratio of [the total epoxy groups of (a) and (b)] : [the acid group of (c)] is 0.5 : 1 to 1 : 0.5.
    Said composition has excellent storage stability and, when used as a coating for automobiles, gives a film superior in appearance, solvent resistance and acid resistance.
