CHEMICAL MEANS FOR PREVENTION OF ACCUMULATION OF ICE, SNOW, AND SLUSH ON RUNWAYS

Abstract

The objective of this contract was to develop a mixture capable of melting snow, ice, and slush at temperatures as low as -10F. Two surviving candidate mixtures were demonstrated as easily prepared in simple, standard mixing equipment, and their storage characteristics as free flowing granules determined at two temperature extremes. The application rate to produce melting at -10F was quite nominal (2 oz/sq ft), and the compositions had at most slight spalling effect on concrete. The prime candidate for runway deicing has the following composition: Tripotassium phosphate 75% - formamide 25%. A second combination proved outstanding for preventive corrosion of steel not under the potentially high stress of landing gear. Quite suitable for road or highway usage was calcium chloride to which was added 1% by weight of Emulsifier STH. This composition retained all its ice-melting qualities with marked corrosion control.
