Abstract: Described is a single-component adhesive made from a radical-polymerized olefinically unsaturated monomer and an air-activated initiator system and characterized in that the adhesive also contains isocyanate and/or silane groups. This makes a dual curing mechanism possible. The more rapid of the two curing reactions gives specific characteristics in the initial stage, e. g. high initial strength, high adhesive strength or high contact strength. The slower of the two reactions produces the definitive characteristics, e.g. final strength or resistance to heat.

Abstract: Film-forming reactive systems for the surface-to-surface bonding and/or coating of substrates, more particularly for heat-sealable coatings are provided. The system is based on an aqueous dispersion of at least two epoxy-curable resins (I) and an epoxy compound as the curing component (II). The epoxy-curable resins are a polyurethane polymer containing epoxy-reactive functional groups present as the curable resin (Ia) and an aqueous dispersion of an acrylate and/or methacrylate homopolymer or copolymer containing carboxyl and/or methylol groups present as an additional curable resin (Ib). Also provided is a method for the production of laminates which employs the reactive system to bond substrates.

Abstract: The invention is a two-component film-forming reactive system for heat-sealable materials. The composition contains at least one resin which is curable with an epoxide and an epoxide compound as a curing agent. The resin which is curable with the epoxide is a mixture of a carboxyl or hydroxyl terminated polyurethane with an acrylate or methacrylate polymer or copolymer having hydroxyl or carboxyl groups.
