- 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.
- Contains flammable solvents and should not be used in confined spaces or near open flames or sparks.
R-503 is ideal for storing penetrant test panels in. The spray tube supplied with the aerosols is an effective way to clean out the star bust cracks on TAM panels.
