Abstract: 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.

Abstract: Cyanoacrylate adhesives which have increased heat resistance, yet also exhibit good storage stability and acceptable cure times, are obtained by using 2-cyanopentadienoic acid esters in combination with alkylene bis-(2-cyanopentadienoates).
