Abstract:
The present invention relates to an organopolysiloxane composition that can be vulcanized at room temperature into an elastomer that is crosslinked by polycondensation and that does not contain alkyltin-based catalysts which exhibit toxicity problems. The invention also relates to novel polycondensation catalysts having a guanidine structure, in silicone chemistry, and to the uses thereof as catalysts for the organopolysiloxane polycondensation reaction.
