ABSTRACT:
An improved adhesive composition of a chlorosulfonated polyethylene, at least one acrylic monomer, such as methyl methacrylate, butyl methacrylate and the like, an amine aldehyde condensation product and optionally a peroxy catalyst in which the improvement comprises the use of a silane of the formula ##STR1## where R.sup.1, --R.sup.2, --R.sup.3 and --R.sup.4 are --H or an alkyl group having 1-5 carbon atoms, --X is --O--R, --R or --OH where --R is an alkyl group having 1-4 carbon atoms, and Y and Z are --H or a monovalent hydrocarbon-containing radical having 1-20 carbon atoms. The improved adhesive is useful for bonding a wide variety of materials and sets rapidly to form durable bonds that withstand exposure to weathering and high humidity conditions. Usually, the adhesive is applied as a two component system in which a mixture of chlorosulfonated polyethylene and acrylic monomers is applied to one surface to be bonded and a mixture of the amine aldehyde condensation product and the silane is applied to the other surface to be bonded and the two surfaces are brought in abutting relationship to form an adhesive bond.
