Two-component adhesive, useful for assembling vehicle bodywork parts, comprises resin and hardeners and is hardened by at least two different types of crosslinking reactions

摘要

Two-component adhesive (A) comprises a resin component (A1) and a hardener component (A2), and hardening occurs as the results of crosslinking by at least two, simultaneous, processes that are not of the same type. Two-component adhesive (A) comprises a resin component (A1) and a hardener component (A2), and hardening occurs as the results of crosslinking by at least two, simultaneous, processes that are not of the same type. One hardeneing process is a reaction, at room temperature, between at least one (A1) and at least one (A2), and at least one other crosslinking system is present. In this system, the active components (X) react by a photochemically and/or thermally activatable reaction and (X) comprises (i) a resin activated by a photoinitiator (PA) or a thermoactivator (TA) and (ii) a photo-inducible PA or heat-inducible TA.
