CONSTITUTION: This fluoropolymer compsn. is prepd. by compounding 50-99wt.% fluoropolymer (A) having cyclic structures in the main chain (and pref. having a number average mol.wt. enough to be solid at normal temp.) and 1-50wt.% polychlorotrifluoroethylene (B) having a number average mol.wt. (pref. of 500-5000) lower than that of polymer A. A moistureproof coating material is prepd. by compounding polymer A with a low-molecular fluoropolymer [e.g. a polymer represented by formula I or II (wherein X<1> to X<4> are each CF3 , C2 F5 , or C3 F7 ; and p, g, and m are each an integer)] other than polymer B. The coating material, having an excellent chemical resistance and low steam permeability, permittivity, and surface energy, is useful for electronic parts such as a circuit board.

2.

Was being made. However, since these resins are essentially water-absorbing, their moisture resistance due to moisture in the air,
There was a drawback that the insulation deteriorates. In order to solve this, in JP-A-6-120001, a fluorine-containing polymer having a ring structure in the main chain is applied to improve the moisture resistance. This fluoropolymer has a large fluorine content, and in particular, a perfluoro polymer has a very low water absorption rate and is excellent in electrical insulation.
However, the water vapor permeability thereof is slightly higher than that of vinylidene chloride resin and high-density polyethylene resin, and is not always sufficient.
