Two-part, ultra-low modulus silicone sealant

摘要

A two part sealant cures rapidly in deep sections when the two parts are mixed together. A first part comprises a hydroxyl endblocked polydiorganosiloxane, non-reinforcing, non-acidic filler, diacetamidosilane chain extender of the general formula and aminoxysilicone compound having from 1 to 100 silicone atoms per molecule and from 3 to 10 aminoxy groups per molecule. A second part comprises a hydroxyl endblocked polydiorganosiloxane, non-reinforcing, non-acidic filler and hydroxyl endblocked polydiorganosiloxane having a degree of polymerization of from 1 to 50.
