RESIN COMPOSITION FOR POWDERY COATING COMPOUND AND ITS PRODUCTION

摘要: PURPOSE:To obtain a resin composition for powdery coating compound having excellent stability during preservation, providing film by using product of this invention coating, the surface showing same flexibility as that thermoplastic in single use, heat resistance and hardness. CONSTITUTION:A mixture (A) containing hydroxyl group and/or amino (B) block isocyanate is dissolved solvent heated to temperature <=block dissociation component B, then precipitated recrystallization method or blending with poor give round powder 0.3-500mu average particle diameter, where ratio A B 0.05-1.5 equivalent produced after based on 1 A, producing shown.
