Abstract
A silicone composition is provided that is resistant to a hydrocarbon fluid, such as a transmission fluid, and other harsh environments when cured. The silicone composition includes a dihydroxy-terminated silicone fluid, a filler material and amine-cured cross-linking agent, the composition containing substantially no plasticizer, and wherein the cured composition can be utilized as a sealant that is resistant to exposure to transmission fluid and high temperatures for extended periods of time. The silicone composition provides effective sealant properties that withstand the foregoing conditions present in the transmission fluids. Methods of making and using the cured silicone sealants made from the present compositions are also provided.
