A method for sealing of components which are exposed to corrosive liquids, and, at ambient temperature, curing silicone - compositions for use thereof

摘要

RTV-1 silicone sealants resistant to deterioration in the presence of aggressive functional fluids are prepared from an organopolysiloxane component comprising a major amount of silanol- functional organopolysiloxane, a primary or secondary amine-functional crosslinker, and both iron oxide and magnesium oxide, optionally together with auxiliary fillers, adhesion promoters, catalysts, and customary additives. The gasket materials are particularly useful in axle and transaxle seals exposed to fuel efficiency-promoting aggressive lubricants.
