Document Type and Number:
WIPO Patent Application WO/2015/020107
Kind Code:
A1
Abstract:
Provided are: a method for manufacturing a powder coating material whereby a hardened film having excellent weather resistance and few voids (gaps) can be formed; a coated article having a hardened film having excellent weather resistance and few voids, and a method for manufacturing a coated article; and a method for manufacturing a carboxyl-group-containing fluororesin having minimal gelling. A method for manufacturing a powder coating material including a powder (X) comprising a composition (α) including a curing agent (D) and a fluororesin (A) having carboxyl groups or alkoxysilyl groups and urethane bonds, the method for manufacturing a powder coating material having (a) a step for melt-kneading a mixture including a hydroxyl-group-containing fluororesin (B), an acid anhydride (C1) or a compound (C2) having alkoxysilyl groups and isocyanate groups, and a curing agent (D), and obtaining a mixture comprising the composition (α), and (b) a step for pulverizing the mixture and obtaining a powder (X).
