ABSTRACT:
An impregnation sealant composition comprises a low viscosity vulcanizable silicone. The silicone is selected from the group consisting of (i) a heat curable silicone composition formed as the reaction product in the presence of a platinum catalyst of a first silicon containing material containing at least two SiH functionalities and having a molecular weight less than 2000 with a second silicon containing material containing at least two ethylenically unsaturated functionalities and having a molecular weight less than 2000, said silicone composition having a ratio of SiH to Si-ethylenically unsaturated functionalities of from about 0.8 to about 1.2; and (ii) a room temperature vulcanizing silicone composition formed as the reaction product of a silicone fluid containing at least two SiOH functionalities and having a molecular weight less than 2000 with a silane cross-linker of formula (I):
