Title:
METAL BONDING FILM COMPOSITIONS
Document Type and Number:
WIPO Patent Application WO2002023556
Kind Code:
A8
Abstract:
An electrically insulating composition for bonding to metal and method for applying the composition in sheet form. The insulating composition comprises a polyolefin polymer adapted for elevated temperature crosslinking and a co-bonding agent mixed with the polyolefin polymer in an amount up to 60 parts of the co-bonding agent to 100 parts of the polyolefin polymer. Preferably, the insulating composition cures in contact with metal pre-heated to elevated temperatures in a range from 140 DEG C to 190 DEG C to provide a lap-shear bond strength between the electrically insulating composition and a metal substrate of from 3.3 MPa to 12 MPa.
