Acidification of dimethyl silicone oils resulted in a material which gave films having a life on the rain spray machine in excess of one hour and which were not affected by the action of jet fuel oil. A product of increased flash point was obtained. An experimental fluorosilicone fluid, Dow Corning QF-1-0065, which has recently become available, was studied for its value as a rain repellent. Acidification with both sulfuric acid and p-toluene sulfonic acids did not produce a material having a life on the rain spray machine equal to that of similarly treated dimethyldiethoxysilane or dimethyl polysiloxane.
