Abstract

PURPOSE: A powder coating polyester composition capable of giving films having improved smoothness free from cissing, comprising a saturated polyester resin having a specific softening point, a polysiloxane, and a nonionic surfactant.
CONSTITUTION: A powder coating composition comprising (A) 100 parts by wt. of a saturated polyester resin having a softening point of 50W200°C, preferably 60W150°C, (B) 0.01W5 parts by wt., preferably 0.1W1 parts by wt. of polydimethylsiloxane, polymethylphenylsiloxane solely or in combination, and (C) 0.005W5 parts by wt., preferably 0.02W0.5 parts by wt. of a nonionic surfactant, e.g. polyethylene glycol distearyl ether. Addition of 5W200 parts by wt. of a modifier, e.g. an aminoplast resin and blocked polyisocyanate, acid anhydride, or epoxy resin to 100 parts by wt. of the polyester resin improves the adhesivity, chemical resistance, and processability of films.
