Claims
- 1. A paint or varnish consisting essentially of a hardenable copolymer in an amount sufficient to form a coating and a solvent for said copolymer, said hardenable copolymer containing the copolymerization radicals of a fluorinated monomer and an acrylamide derivative wherein:
- (a) the fluorinated monomer radicals originate from the association of vinylidene fluoride and at least one fluorinated monomer selected from tetrafluoroethylene, chlorotrifluoroethylene, hexafluoropropylene, or a mixture of at least two of the three monomers, and
- (b) the radicals of the acrylamide derivative originate from one of the compounds of the formula: ##STR4## wherein R is H or CH.sub.3, ##STR5## with: n representing a number from 0 to 8, and
- x representing a number from 0 to 3.
- 2. The paint or varnish of claim 1 wherein for 100 moles of the totality of the fluorinated monomers, the following are used:
- (a) 50 to 98 moles of vinylidene fluoride
- (b) 2 to 50 moles of fluorinated monomer selected
- from tetrafluoroethylene, chlorotrifluoroethylene, hexafluoropropylene, or the mixture of at least two of these three monomers, and
- (c) 2 to 30 moles of acrylamide derivative per 100 moles of the totality of the fluorinated monomers.
- 3. The paint or varnish of claim 1 or 2 including a hardening agent capable of cross-linking said copolymer at a temperature of about 0.degree. to 260.degree. C.
- 4. The paint or varnish of claim 1, wherein the association for 100 moles of fluorinated monomers is constituted of:
- (a) 50 to 98 moles of vinylidene fluoride, and
- (b) 2 to 50 moles of fluorinated monomer selected from tetrafluoroethylene, chlorotrifluoroethylene, hexafluoropropylene, or a mixture of at least two of these three monomers.
