A review is presented on cold-curing, one-component cyanoacrylate adhesive systems. Curing and adhesion mechanisms are discussed, as is pretreatment of substrates, strength and chemical resistance of the adhesives, and methods of debonding. Their suitability as bonding agents for rubbers and plastics is considered. See also <i>AATA</i> <b>19-1062</b> for a discussion of the role of adhesives in the bonding of plastics. -- AATA
