ABSTRACT:
Adhesion of organic polymer-based compositions to substrate surfaces is enhanced by incorporating into such organic polymer-based compositions an effective amount of an admixture comprising at least one phenolic novolak resin, at least one polyepoxide, and an effective amount of at least one crosslinking agent. The organic polymer-based compositions containing the described admixtures are bonded to metal and other substrates over a wide temperature range, including temperatures substantially below the activation temperatures at which prior art adhesion promoters are most effective.
