ABSTRACT:
A silicone sealant which is stable in the absence of moisture and cures upon exposure to moisture to give an elastomer with a controllable modulus is produced by mixing a polydiorganosiloxane having both vinyl and alkoxysilethylene endblocking, alkoxy silane crosslinker, titanium catalyst, and optional filler. The modulus is controlled by varying the ratio of vinyl to alkoxysilethylene endblocking present on the polymer.
