THE DEVELOPMENT AND EVALUATION OF HEATRESISTANT, RAIN-EROSION-RESISTANT COATINGS.
Abstract
A coating based on Viton A, a fluorocarbon polymer, was developed that provides good resistance to rain erosion (abrasion), as determined by the Jet Abrader Method, after exposure to high temperatures or to weathering. The abrasion resistance of Viton A coating was decreased only slightly by exposure at 500F for 15 hours or by exposure for 300 hours in an Atlas Twin-Arc Weather-Ometer. A number of silicon-nitrogen polymers were synthesized and evaluated, and, although some of these polymers had outstanding resistance to high temperatures, none of the coatings prepared with these polymers had sufficient abrasion resistance to be useful for the purpose of the project.
