Abstract
A method for continuously producing a room temperature vulcanizable composition is disclosed. A base mixture of a silanol stopped fluorosilicone polymer, a silica filler and iron oxide are processed in an extruder at an elevated temperature between about 50 and 200.degree. C. Thereafter, a tin based catalyst, an acetoxy cross-linking agent and an optional adhesion promoter are added to the extruder near the exit port. The resulting material has improved storage stability.
