The present disclosure relates to a process of manufacturing curable precursor of a structural adhesive composition. According to another aspect, the present disclosure is directed to method of bonding two parts.

Process of manufacturing a curable precursor of a structural adhesive composition

The present disclosure relates generally to the field of adhesives, more specifically to the field of structural adhesive tapes, in particular for use in bonding metal parts. The present disclosure also relates to a method of bonding two parts and to a composite article. The present disclosure is further directed to the use of a structural adhesive tape for industrial applications, such as construction and automotive applications, in particular for body-in-white bonding applications in the automotive industry.

Elastic one-part structural adhesive tape

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.
