Abstract : The report discusses the development of a new chemical stripper. It was found that the use of sulfuric acid in combination with ultrasonic vibration (40Kc.) was an efficient method to strip and disintegrate PT201 thermosetting resin from the surface of manometer housings. Three such housings were effectively cleaned by this method within a period of ten minutes and were in accordance with the requirements of MS 60.14Ba, Maintenance Cleaning of Propellant Utilization Manometers.
