Abstract
Methods of bonding highly-fluorinated thermoplastics to elastomers are described. The methods include apply primers comprising at least one aromatic silane and at least one amino-silane to an uncured elastomer and irradiating the primer with actinic radiation before or after applying the highly-fluorinated thermoplastics. The elastomer may then be cured to provide articles having good adhesion between the highly-fluorinated thermoplastic and the cured elastomer.
Claims20
A method of forming a multilayer article comprising:
- (a) applying a primer comprising (i) an aromatic silane and (ii) an amino-silane onto a composition comprising an uncured elastomer;
- (b) applying a highly-fluorinated thermoplastic onto the primer;
- (c) irradiating the primer with actinic radiation;
- and
- (d) forming a bond between the highly-fluorinated thermoplastic and the composition.
