A system for a cross-linkable hot-melt adhesive, comprising (A) a first composition which contains no epoxy groups and comprises: (a) at least one polymer chosen from thermoelastic polymers and synthetic rubbers; (b) at least one compound containing at least one grouping which may react with epoxy groups; (c) at least one tackifying resin; and (d) if required, at least one plasticizer or a wax; and (B) a second composition which comprises: (a) if required, at least one polymer chosen from thermoelastic polymers and synthetic rubbers; (b) at least one compound containing at least one epoxy group; (c) at least one tackifying resin; (d) if required, at least one plasticizer or a wax; and (e) if required, at least one activator of the reaction between the reactive groupings of component (Ab) and the epoxy functions of component (Bb). The system may be used to assemble two objects. |
