1-component alkoxy curing RTV silicone sealant compositions having extended tooling times

摘要

A room temperature vulcanizing alkoxy curing silicone composition cured by a dual catalyst system comprising either (C4H9)Sn(O2CCH3)(O2C(CH2)10CH3) or an approximately equimolar mixture of dibutyltin diacetate and dibutyltin dilaurate or mixtures thereof whereby tooling time is increased without deleterious effects upon cured performance properties.
