Abstract
A multi-layer structure includes a layer of a fluoropolymer bonded to a substrate. The structure is prepared by exposing a bonding composition to actinic radiation, such as ultraviolet radiation, to form the bond. The bonding composition includes a light-absorbing electron donor.
Claims44
A method of bonding a fluoropolymer to a substrate comprising:
- providing a bonding composition between a fluoropolymer and a substrate, the bonding composition including a light-absorbing electron donor;
- and
- exposing the bonding composition to actinic radiation, wherein the bonding composition is exposed to actinic radiation through the fluoropolymer, through the substrate, or both.
A method of bonding a fluoropolymer to a substrate comprising:
- treating a surface of a fluoropolymer with a bonding composition, the bonding composition including an aromatic amine;
- contacting the treated surface of the fluoropolymer with a surface of a substrate;
- and
- exposing the bonding composition to actinic radiation, wherein the bonding composition is exposed to actinic radiation through the fluoropolymer, through the substrate, or both.
