SILICONE EMULSION HAVING IMPROVED FREEZE/THAW RESISTANCE A method of improving the freeze/thaw stability of an anionically stabilized silicone emulsion useful as a sealant, has been developed. The method comprises the use of nonoxynol-10 in combination with ethylene glycol added to an emulsion comprising 100 parts by weight of an anionically stabilized, hydroxyl endblocked polydiorganosiloxane present as an emulsion of dispersed particles in water, from 0.075 to 0.75 part by weight of dialkyltindicarboxylate, from 0.2 to 5 parts by weight of silane of the formula RSi(OR )3, and from 50 to 200 parts by weight of inert, non-siliceous filler. |
