SILICONE WATER-BASED ELASTOMERIC CAULKING MATERIAL Abstract A silicone caulking material obtained by mixing an anionically stabilized, hydroxyl endblocked polydiorgano- siloxane in an aqueous emulsion, dialkyltindicarboxylate, alkylorthosilicate, and inert, non-siliceous filler is capable of yielding an elastomer upon removal of the water immediately upon mixing of the ingredients. When the caulking material also contains 2-amino-2-methyl-1-propanol, the emulsion also has a useful shelf life in that the emulsion shows no gelation upon aging. The physical properties of the elastomer produced by removing the water from the emulsion do not change appreciably during the useful life of the caulking material.
