- b. 80-10% of at least one ethylene-tetrafluoroethylene copolymer having a melting point from about 180.degree. C. to about 285.degree. C. and containing 68 mol % of chemically combined tetrafluoroethylene.
- 2. A coating composition according to claim 1, and being capable of undergoing film formation upon being heated at a temperature between 260.degree. C. and 300.degree. C., for between 1 and 2 minutes.
- 3. A coating composition according to claim 1, and further comprising at least one fluidizing solvent.
- 4. A coating composition according to claim 1, and further comprising at least one pigment.
- 5. A coating composition according to claim 3, and further comprising at least one pigment.
- 6. A coating composition according to claim 1, and further comprising at least one inert filler.
- 7. A coating composition according to claim 3, and further comprising at least one inert filler.
- 8. A coating composition according to claim 1, and further comprising at least one additive selected from the group consisting of surfactants, stabilizers, anti-oxidants and ultraviolet absorbers.
- 9. A coating composition according to claim 3, and further comprising at least one additive selected from the group consisting of surfactants, stabilizers, anti-oxidants and ultraviolet absorbers.
