Surface Chemistry of Adhesion to Aluminum

Understanding the microstructure and chemistry of the aluminum surface is the key to designing coating and structural bonding systems that endure. The focus of this article is the examination of concepts common to all polymer/aluminum bonding applications and to discuss some common surface treatments alter the surface chemistry and microstructure and how these treatments affect adhesion. Topics covered in this review include: discussion of the untreated aluminum surface, adhesion to aluminum surfaces, prevention of hydration of the bonded interface, and pretreatments,
