Abstract
A fluororesin powder coating composition having high light resistance and being excellent in blocking resistance and smoothness of the coating film when coated, and a fluororesin powder to be used for a powder coating material, are presented.The fluororesin powder coating composition is made by using as the main material resin a composite fluorinated copolymer powder having a core/shell structure wherein core particles are made of a fluorinated copolymer and their surfaces are covered by e.g. a (meth)acrylate resin having a glass transition temperature higher than that of the core particles. The core/shell structure is formed by seed polymerization wherein fluorinated polymer particles are used as seeds.
