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.
