Abstract
Reactive adhesive film, comprising (a) a polymeric film-forming matrix, (b) at least one reactive monomer or reactive resin, and (c) a reagent selected from the group consisting of a radical initiator and an activator, and a reactive 2-component adhesive film system for bonding various materials, such as metal, wood, glass and/or plastic
Claims17
A reactive adhesive film, comprising (a) a polymeric film-forming matrix, (b) at least one reactive monomer or reactive resin and (c) a reagent selected from the group consisting of a radical initiator and an activator.
A method for producing a reactive adhesive film comprising the steps of:
- 1. dissolving and/or finely distributing the ingredients in one or more solvent(s) and/or water,
- 2. mixing the dissolved or finely distributed ingredients,
- 3. coating a release liner or release paper, a backing material or a pressure sensitive adhesive with the mixture of dissolved or distributed ingredients according to step 2,
- 4. evaporating the solvent and/or water, and
- 5. optionally winding the reactive adhesive film into a roll,
- wherein the ingredients include (a) a polymeric film-forming matrix, (b) at least one reactive monomer or reactive resin and (c) a radical initiator, or an activator.
