Claims
- 1. A perfluorocarbon paint composition containing hollow double-shell electroconductive particles comprising hollow inner shells formed substantially of amorphous silica or a silica-containing material and outer shells coated on surfaces of the inner shells formed substantially of antimony-containing tin (IV) oxide., the percentage of said hollow double-shell electroconductive material based on the solids of said perfluorocarbon paint composition being in the range of 1 to 30% by volume,
- and in which paint composition the perfluorocarbon resin comprises 10% to 50% by weight of a copolymer of either tetrafluoroethylene and perfluoroalkyl vinyl ether or a copolymer of tetrafluoroethylene and hexafluoropropylene and 50to 90% by weight of polytetrafluoroethylene.
- 2. The paint composition of claim 1 in which the antimony content of the tin (IV) oxide in the outer shell is about 1% to 30% by weight of the tin oxide.
- 3. The paint composition of claim 1 in which the percentage of electroconductive material is from 6 to 20% by volume.
- 4. The paint composition of claim 1 in aqueous form.
