Fundamentals of Adhesionwith the chemistry and physics of surfaces and interfaces as well as the mechanics of deformation and fracture of adhesive joints. In this overview, these various aspects of adhesion are discussed. We begin by describing the general types of adhesive bonds. This is followed by sections on solid surf

Surface Preparation for Adhesive Bondingnd bond performance properties. A single molecular layer of contaminant can prevent proper wetting by the adhesive, or a weak substrate boundary layer can provide the “weak link” for premature failure. For these reasons, much adhesive application effort and technical study has been focused on the ad

Casein and Mixed Protein Adhesivesar, the chemical structures of these three proteins are different enough to give unique properties to the adhesives which are made from each. This chapter will primarily cover the casein adhesives, but will touch also on some of the properties common to the three protein sources and the use of combi

Butyl Rubber and Polyisobutyleneifiers and modifiers. The principal difference between these polymers is that butyl is a copolymer of isobutylene with a minor amount of isoprene, which introduces unsaturation, while polyisobutylene is a homopolymer.
