ROOM TEMPERATURE-CURING ORGANOPOLYSILOXANE COMPOSITION

摘要

PURPOSE: To provide a room temperature-curing organopolysiloxane composition rapidly curing and capable of affording a cured product having a sufficient hardness without causing problems such as toxicity, cracking or discoloration. CONSTITUTION: This room temperature-curing organopolysiloxane composition comprises (A) an organopolysiloxane containing at least 2 hydroxy groups bound to silicon atom in one molecule, (B) an organosilicon compound represented by the following formula (I): RaSiX4-a (wherein, Rs are each a 1-10C substituted or a 1-10C unsubstituted monovalent hydrocarbon; X is a hydrolyzable group; and (a) is an integer of 0-3) and/or its partial hydrolyzate condensate and (C) a bismuth compound-based curing catalyst.
