Two-part, ultra low modulus silicone sealant

U.S. Patent Number: 5290826

Abstract: 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, non-reinforcing, non-acidic filler, diacetamidosilane chain extender of the general formula ##STR1## and 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, non-reinforcing, non-acidic filler, and water. When mixed together, the two parts cure rapidly in deep sections.
