Abstract
Reactive adhesive film for bonding various materials, including plastic to metal, the adhesive film comprising (a) a polymeric film-forming matrix, (b) at least one epoxide-functionalized (meth)acrylate or vinyl monomer and (c) a reagent selected from an initiator, in particular a free-radical initiator, or an activator. Further disclosed are reactive adhesive film systems comprising two reactive adhesive films. Methods for producing reactive adhesive films, and methods are also disclosed.
Claims20
A reactive adhesive film system comprising two reactive adhesive films comprising (a) a polymeric film-forming matrix, (b) at least one reactive monomer comprising an epoxide-functionalized acrylic ester or epoxide-functionalized methacrylic ester or an epoxide-functionalized vinyl compound and (c) a reagent selected from an initiator, or an activator, wherein the first reactive adhesive film comprises a radical initiator and the second reactive adhesive film comprises an activator.
A kit providing a two-component adhesive film system, comprising
- (i) at least one first reactive adhesive film comprising (a) a polymeric film-forming matrix, (b) at least one reactive monomer comprising an epoxide-functionalized acrylic ester or epoxide-functionalized methacrylic ester or an epoxide-functionalized vinyl compound and (c) a reagent selected from an initiator, or an activator which comprises a radical initiator, and
- (ii) at least one second reactive adhesive film comprising (a) a polymeric film-forming matrix, (b) at least one reactive monomer comprising an epoxide-functionalized acrylic ester or epoxide-functionalized methacrylic ester or an epoxide-functionalized vinyl compound and (c) a reagent selected from an initiator, or an activator which comprises an activator.
