THE DEVELOPMENT AND EVALUATION OF HEAT-RESISTANT, RAIN-EROSION RESISTANT COATINGS.
Abstract
Five fluorocarbon polymers (Viton A, Viton B, Exon 461, Fluorel 2141, and Krynar) and two silicone polymers (Silastic 588 and Silastic 589) have been ivestigated for use in preparing abrasion-resistant coatings that will be serviceable after exposure to temperatures above 600 F for short periods of time. The Viton fluorocarbon polymers were the best of the materials studied. Viton coatings were prepared that equaled a commonly used neoprene coating in abrasion resistance, as determined by the jetabrader method. These Viton coatings retained approximately 85% of their original abrasion resistance after being heated for 1 hour at 600 F and for 15 minutes at 650 F. Because of these encouraging results, efforts are now being made to develop a satisfactory primer system for Viton coatings and to prepare coupons coated with them for evaluation in the rain-erosion tester at the University of Cincinnati.
