Abstract
The present disclosure relates to a curable precursor of a structural adhesive composition, comprising: a) a cationically self-polymerizable monomer; b) a polymerization initiator of the cationically self-polymerizable monomer which is initiated at a temperature T1; c) a curable monomer which is different from the cationically self-polymerizable monomer; and d) a curing initiator of the curable monomer which is initiated at a temperature T2 and which is different from the polymerization initiator of the cationically self-polymerizable monomer. According to another aspect, the present disclosure is directed to a partially cured precursor of a structural adhesive composition. According to still another aspect, the present disclosure relates to a method of bonding to parts. In yet another aspect, the disclosure relates to the use of a curable precursor or a partially cured precursor as described above, for industrial applications, in particular for body-in-white bonding applications for the automotive industry.
