R-504 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 flash dry rate material and as such is ideal for penetrant wipe removal, especially for the verification of indications. A cotton swab is moistened with R-504 and suspected indications are lightly wiped from the surface. The inspector can evaluate the indication by the rate of penetrant bleed back. The rapid drying of R-504 is ideal for this application as it does not blur the indication. The aerosol comes with a spray tube that facilitates pin point application which is ideal for cleaning the star indications on TAM panels. 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-504 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 #9008 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-504 is a phenol free solvent. R-504 is flammable and should not be used in confined spaces or near open flames or sparks.
