Abstract

An adhesive is disclosed for use in flexible circuitry, laminates and electrical products. The adhesive has improved flexibility and adhesive properties. It may be applied in solution form or may be cast as a free-standing film which is later heated and compressed to give adhesive properties. The adhesive comprises a phenolaldehyde resin or other phenolic resin, an epoxy resin and an elastomer.
