Hydroxybenzamines of the general formula have been claimed to improve the adhesion of a wide range of coatings to zinc and cadmium and other metallic substrates when used as either pretreatment primers or additives [63]. Ethylenically unsaturated hydroxy — functional amines have been claimed to improve the adhesion of water-based systems [64], and amines have been examined as adhesion promoters for aromatic isocyanate cured adhesives on glass and other substrates [65]. Primary aliphatic amines are claimed to improve the bondability of polyolefines [66] and an oxyethylated polyethylene

polyamine claimed for polymer-to-polymer bonding [67].

4-Ethylpiperidine has shown promise as an adhesion promoter [68], aminoethylpi — peridine has been shown to be beneficial in steel-epoxide systems [48], and primers based on piperidine derivatives improve the adhesion of adhesives to aluminum and stainless steel [69]. Pyridene derivatives such as 2-(2-methylethyl)pyridene are claimed to be effec­tive primers for crystalline and nonpolar polymers to be bonded with cyanoacrylate adhesives [70].
