E-57 is a Method B (lipophilic) inspection penetrant emulsifier approved to AMS-2644 for use with FP-94, FP-93A(M), FP-95A(M), and FP-97A(M) fluorescent (Type 1) post emulsifiable penetrants. Method B emulsifiers are used either by immersion or flow on. The emulsifier is used as supplied. The penetrant covered part is immersed into the emulsifier and then removed and allowed to drain from 30 seconds to 3 minutes depending upon the part surface roughness. The emulsifier will render the PE penetrant water washable during the dwell time. This step is then followed by a wash step in the Method B process.
E-57 is listed on the Qualified Products List for AMS-2644E. It meets the requirements of ASME Boiler and Pressure Vessel Code, ASTM E-165, and ASTM E-1417, and for penetrant inspection materials.
