FAST CURING, NEUTRAL SILICONE SEALANTS

摘要

An improved silicone sealant consists essentially of trialkoxysilethylene endblocked polydiorganosiloxane, fumed silica reinforcement, diorganodialkoxysilane chain extender and titanium catalyst. The improved sealant has a faster cure, lower modulus and improved physical properties when compared to a similar sealant made with an alkyltrialkoxysilane crosslinker.
