Composição organopolissiloxânica que não contém um catalisador metálico, sistema bicomponente, composição poliorganossiloxânica monocomponente, elastomero, compostos e usos de um catalisador de policondensação.

摘要

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.
