@ An aqueous silicone elastomeric emulsion is a storage stable, paste-type material useful as a caulking material. The caulking material is obtained by mixing an anionic emulsion containing dispersed particles of hydroxyl endblocked polydiorganosiloxane, dialkyltindicarboxylate, silane of the formula RSi(OR') 3 where R is a monovalent hydrocarbon radical of from 1 to 4 carbon atoms inclusive and R' is a lower alkyl radical of from 1 to 4 carbon atoms inclusive or a radical of the formula -N=CR 2 , and inert, non-siliceous filler. |
