  • Process for the continuous production of RTV silicone rubber compositions
    Patent number: 6031026
    Abstract: In a first step, a crosslinkable organopolysiloxane oil (2) is mixed with an inorganic filler (3) in a flow jet mixer (1) to form a flowing silicone rubber compound. In a second step, the silicone rubber compound is fed into a tank (6) equipped at the bottom with a vacuum discharge pump (8) and maintained in vacuum where the compound is continuously deaerated, and a thixotropy controlling agent (10) is then added and mixed with the compound in a mixer (9). In a third step, a crosslinking agent (12) is added and mixed with the silicone rubber compound in a KRC kneader (11), and the compound is degassed in a mixer (13). The process continuously produces an RTV silicone rubber composition which is anti-sagging and improved in applicability on use.
