<p>PURPOSE:To titled composition, prepared by incorporating an emulsion of a fluorine compound with an inorganic powder and a pH adjustor, usable for washing or preventing the staining of airframes of aircraft, and having improved cleaning and water repellent effects. CONSTITUTION:A composition prepared by incorporating an emulsion obtained by dispersing a fluorine compound, preferably a low polymer of an alkyl (fluoro) methacrylate, in water preferably with a surfactant, with an inorganic powder, e.g. hydrous silicic acid, soda glass, silica sand or pyrophyllite, and a pH adjustor, e.g. sodium silicofluoride or sodium metasilicate. EFFECT:Smooth airframes of aircraft with improved fuel efficiency, and useful for preventing the corrosion of the airframes.</p> |
