<p>CYANOACRYLATE ADHESIVE COMPOSITION Adhesive composition consisting of?-cyanoacrylate, one or more sulphonic acid derivatives as stabilizers and conventional additives. The stabilizers are sulphonic acid derivatives having the general formula < IMG > (I) in which R1 is a trimethylsilyl group, R2 a halogen atom, an alkyl group, a perfluoroalkyl group, a cycloalkyl group or an aryl group or R1 and R2 together, accompanied by cyclization, represent a group of the general formula < IMG > (II) in which Z is a substituted or unsubstituted phenylene radical. Preferred are combinations of compounds in which in one R1 is a trimethylsilyl group and in the other R1 and R2 form the aforementioned ring group. (Dihydroxy)-organylboranes and bis(dihydroxyboryl)derivatives can be used as costabilizers. The storage stability obtained with the stabilizers according to the invention is excellent, without impairing the setting rate and the strength of the bonds obtained.</p> |
