Zusammenfassung: | The present invention provides moisture curable silicone polymers and compositions thereof, having improved resistance to automotive oil and high temperature. The silicone polymers contain terminal moisture curable functional groups and a linkage that separate the siloxane backbone from the moisture curable functional groups. The linkage confers oil resistance at elevated temperatures to the cured compositions. The silicone polymers and compositions cure by way of a condensation mechanism in the presence of moisture and a catalyst. The silicone polymers and compositions are particularly useful as sealants and gaskets in automotive powertrains. |
