R-503 is a class 2 (non-halogenated), Method C inspection penetrant remover. It is designed for use in the solvent wipe technique for penetrant inspection in general metalworking, welding, nuclear and aerospace applications. It is a moderate dry rate material and is ideal for penetrant wipe removal and pre-inspection surface cleaning. As a pre-cleaner it is sprayed directly on the test surface. As a penetrant remover it is sprayed onto wiping media and then the penetrant wiped from the surface. The remover should not be sprayed directly on to the test surface to remove the excess penetrant as the sensitivity will be impaired.
R-503 is listed on the Qualified Products List for AMS-2644E. It meets the requirements of AMS-2647, ASME Boiler and Pressure Vessel Code, ASTM E-165, ASTM E-1417, ISO- 3452-2005, and Pratt & Whitney PMC #9094 for penetrant inspection materials. It is low in Sulfur, Chlorine, Fluorine and other Halogens, making it safe for use on Titanium and high Nickel alloys found in aerospace, medical and nuclear components.
R-503 is free of petroleum solvents. R-503 is flammable and should not be used in confined spaces or near open flames or sparks.
