Activator for cyanoacrylate adhesives

摘要

Organic compounds containing the structural element -N=C-S-S-C=N- are suitable in dilute solution as activators for the accelerated hardening of cyanoacrylate adhesives. As compared with the known accelerators, they have the following advantage: good accelerating action, but they nevertheless permit a long waiting time between application of the activator and application of the adhesive. In addition, they avoid spontaneous, merely superficial hardening.
