Abstract
Abstract The strength of the bond obtained between substrates with the aid of phenoplasts, modified phenoplasts and/or epoxy resins, e.g. between fibrous material and an elastomer on vulcanization thereof, is improved by applying, to at least one of the substrates, in addition to a preformed phenoplast, modified preformed phenoplast, and/or preformed epoxy resin, and drying thereon before the assembly thereof with the other substrate, as an adhesion promoter, a quantity of m-aminophenol, which may be blended in a phenoplast adhesive, such as an RF dip or an RFL dip, or may be blended in the elastomer latex used for forming an RFL dip. Adhesive/promoter blends and latex/promoter blends for forming the same are also disclosed.
