Zusammenfassung:According to one aspect, the present disclosure relates to a curable precursor of a structural adhesive composition, comprising: a) a thermally curable resin; b) a thermal curing initiator for the thermally curable resin; c) a radiation self-polymerizable multi-functional compound comprising a polyether oligomeric backbone and at least one free-radical (co)polymerizable reactive group at each terminal position of the oligomer backbone; and d) a free-radical polymerization initiator for the radiation self-polymerizable multi-functional compound; wherein the free-radical polymerization initiator is activated by visible light.
