(54) | Room temperature vulcanizing silicone rubber compositions and process for making |
(57) A one-component room temperature vulcanizable silicone rubber composition comprising (A) silanol end-terminated polyorganosiloxane base polymer, (B) organotriacyloxysilane cross-linker, (C) polysiloxane-polyether copolymer rheology modifier and (D) particulate silica. The rheology modifying agent is particularly useful for adjusting the viscosity and plateau stress of the silicone rubber compositions.
