ABSTRACT:
A thermosetting powder coating composition which contains a resin composition containing (a) 60 to 97 weight % of a fluororesin having reactive group for crosslinking in the molecule which contains 10 weight % or more of fluorine and has glass transition temperature in the range from 35.degree. to 120.degree. C., (b) 3 to 40 weight % of a hardener which can form crosslinking by reaction with the reactive group for crosslinking in the fluororesin (a), (c) 0.01 to 10 weight parts of a synthetic wax or a natural wax based on 100 weight parts of the resin composition and (d) 0.001 to 1.0 weight parts of a material as a coupling agent based on 100 weight parts of the resin composition, forms a coating layer which has the same degree of water repellency and slipping property as those formed from polytetrafluoroethylene powder while the excellent weatherability, acid resistance and adhesion to substrates are retained. A coating layer having excellent adhesive property and impact resistance can be formed therewith on a stainless steel substrate without chemical pretreatment or coating with a primer.
