Silyl peroxides. Some chemical and physical effects on adhesion promotion

Some chemical and physical effects on adhesion promotion with the silyl peroxides are described in this paper. On the basis of experimental findings, a mechanistic account for the silyl peroxide promoted adhesion is presented. Adhesion promotion with the silyl peroxides has been shown to be primarily a chemical phenomenon. Formation of covalent bonds, including perhaps hydrogen bonding, through siloxane linkages extending across the interface, is believed to be chiefly responsible for the observed adhesion. Adhesion due to surface oxidation is not considered to be a major contributing factor with the silyl peroxide systems.
