A two part sealant cures rapidly in deep sections when the two parts are mixed together. A first part consists essentially of a hydroxyl endblocked polydiorganosiloxane, a non-reinforcing, non-acidic filler, a diacetamidosilane chain extender of the general formula (see formula I) and an aminoxysilicone compound having from 1 to 100 silicone atoms per molecule and from 3 to 10 aminoxy groups per molecule. A second part consists essentially of a hydroxyl endblocked polydiorganosiloxane, a non-reinforcing, non-acidic filler, and water. When mixed together, the two parts cure rapidly in deep sections. |
