摘要:
A stabilized fluorine-containing polymer powder having an average particle size of 5 to 100 μm is prepared by contacting a fluorine-containing polymer powder, which is prepared by milling the fluorine-containing polymer and removing fine particles, fibrous particles and coarse particles by classification, with a fluorinating agent so that the total number of unstable terminal groups is decreased to 7 to 50 per 106 carbon atoms. This is a fluorine-containing polymer powder achieved a high coating efficiency in an electrostatic coating method and provides a film having good properties such as heat resistance, non-tackiness, low frictional property, chemical resistance, etc.

An amino group-containing metal compound such as a coupling agent having an amino group is dispersed in a fluoroelastomer coating composition comprising a fluoroelastomer and a polyol curing agent which are dissolved or dispersed in a liquid medium. The resulting fluoroelastomer coating composition can form an elastomer coating layer directly on a metal surface using no primer, and improve antifreeze resistance and deterioration of the coating film after compression at high temperatures for a long time.

A fluorine-containing coating composition obtainable by compounding a macromolecular material with an ethylene-tetrafluoroethylene copolymer having an average particle diameter of 1 to 30 μm. The macromolecular material is one occurring as a liquid or in a state dissolved in a solvent at below the melting initiating temperature of the ethylene-tetrafluoroethylene copolymer. Furthermore, a volume ratio between the ethylene-tetrafluoroethylene copolymer and the macromolecular material is 35:65 to 95:5.
