ABSTRACT:
It is to provide a production process by which gelation can be prevented, in a case where a solvent is removed from a curable fluororesin to obtain a chief material resin, and then coating additives such as a curing agent are mixed to produce a powder coating composition, or in a case where a curable fluororesin, a curing agent and various additives are dissolved or dispersed in a solvent to prepare a raw material solution, and the solvent is removed from the raw material solution to directly produce a powder coating material.To a solution or dispersion of a curable fluorinated copolymer (A), a gelation inhibitor (B) is added, followed by mixing, or a gelation inhibitor (B), a curing agent (C) and as the case requires, various additives (D) are added, followed by mixing, and the solution or dispersion is supplied to a thin-film vacuum evaporator to remove the solvent.
