Abstract:

The development of a new and improved rain repellant suitable for use on the glass windshields of high-speed aircraft not equipped with windshield wipers is reported. Recommendations are made for the use of a formula which is a liquid repellant consisting of dimethyldiethoxy-silane acidified by the addition of a small amount of sulfuric acid and a minor amount of n-hexyl ether which serves as a solvent. The rain repellent is packaged as an aerosol with Freon 12 as the propellant in the proportion of 2 parts active material to 3 parts propellant. Author
