Abstract
Compositions for fixing a non-conductive material to a reinforcing layer are provided. In one embodiment, the composition being used to fix a non-conductive material on a reinforcing layer including a novolac produced by condensation of a substituted or unsubstituted phenol with an aldehyde in the presence of a catalyst, and optionally other additives.
Claims16
An article of manufacture, comprising:
- a reinforcement layer;
- an adhesive composition disposed on the reinforcement layer, the adhesive composition comprising:
- a) a novolac produced by condensation of a substituted or unsubstituted phenol with an aldehyde, where the molar mass of the novolac is from 250 to 1000 g/mol;
- b) a catalyst selected from the group consisting of boron(III) halides and/or amine complexes thereof, imidazoles, acetylacetonates, tin(IV) chloride, tertiary amines, tetramethylguanidine, and combinations thereof;
- and
- c) optionally other additives;
- and
- a nonconductive material disposed on the reinforcement layer and the adhesive composition.
