Abstract
A handling film to be applied to an adhesive, wherein the handling film comprises a polyhydroxyamino ether thermoplastic, a monofunctional epoxy, and a carboxylated nitrile butadiene elastomer.
Claims20
A handling film comprising:
- a polyhydroxyamino ether thermoplastic;
- a monofunctional epoxy;
- a carboxylated nitrile butadiene elastomer;
- wherein the monofunctional epoxy reacts with an amine of the polyhydroxyamino ether thermoplastic substantially limiting reaction between the carboxylated nitrile butadiene elastomer and polyhydroxyamino ether thermoplastic.
