  • Method of treating metal foil to improve peel strength
    Patent number: 5071520
    Abstract: A technique for improving the peel strength of copper and copper based alloy materials, and particularly for copper or copper based alloy materials which may be wrought or electrolytically deposited copper foil having an antitarnish treatment applied thereto, preferably by the use of a chromate-containing solution. The material is subjected to a rinse containing a silane coupling agent, which preferably is an organofunctional silane, and more preferably is an alkoxysilane derivative. Both the original peel strength and the peel strength after storage of the material so treated is enhanced.
