Abstract
Polymeric coupling agents offer a practical alternative and improvements to chrome etching pretreatments presently utilized on aluminum and steel. A copolymer has been polymerized containing both d-diketone and epoxy functional groups. This copolymer is being evaluated as a potential polymeric coupling agent for bonding polymers aluminum. X-ray Photoelectron Spectroscopy indicates interaction of the coupling agent with the aluminum oxide surface. Quinone-amine polyurethanes (QAPs) are being evaluated as potential polymeric coupling agents for the steel-epoxy system. Infrared Spectroscopy and X-ray Photoelectron Spectroscopy indicate chemical interactions of the coupling agent with both the steel and epoxy surfaces.
