Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
78 words
An adhesive composition comprising A. 5-40 percent by weight, based on the weight of composition, of a copolymer of 30-70% by weight vinylidene fluoride units and complementally 70-30% by weight hexafluoropropylene units, and B. 0.5-3 percent by weight, based on the weight of composition, of an isocyanate made by reacting one mole trimethanolpropane with three moles toluene diisocyanate, in C. sufficient organic solvent for both A and B to make the composition components total 100 percent by weight.
Claim 2
Dependent Claim
78 words
An adhesive composition comprising A. 5-40 percent by weight, based on the weight of composition, of a copolymer of 30-70% by weight vinylidene fluoride units and complementally 70-30% by weight hexafluoropropylene units, and B. 0.5-3 percent by weight, based on the weight of composition, of an isocyanate made by reacting one mole trimethanolpropane with three moles toluene diisocyanate, in C. sufficient organic solvent for both A and B to make the composition components total 100 percent by weight.
Claim 3
Dependent Claim
27 words
A laminated article in which a corona surface treated oriented fluorocarbon copolymer film is laminated to a substrate by an adhesive composition as claimed in claim 1.
Claim 4
Dependent Claim
97 words
A process in which an oriented, melt-fabricable fluorocarbon copolymer film is laminated to another such film or to a substrate by first treating the surface of each film to be laminated to corona discharge in an atmosphere of acetone, treating the surface of each such film with an adhesive composition as claimed in claim 1 and then pressing the coated film to another such coated film or to a substrate and heating for at least 1.5 minutes at from 150 to 175 0 C at a pressure of from 55 to 83 kPa (8 to 12 psi).
