A Method B lipophilic emulsifier, ZE-4B diffuses into the penetrant to clear the penetrant from the surface of the part being inspected. It is rinsed from the part by water, carrying penetrant off the part surface. Designed to be used with post-emulsifiable penetrants Level 2 ZL-2C, Level 3 ZL-27A or Level 4 ZL-37, benefits include low volatility and a high flash point so ZE-4B can be used in open immersion tanks. •Low volatility •High flash point •Fast acting for quick processing times •Supplied ready to use" •Biodegradable •Safe to use on all aerospace alloys, e.g. aluminium, steel, nickel, titanium Product Properties NDT TypeFluorescent Penetrant Testing, Visible Penetrant Testing Penetrant TypeType 1, Type 2 Penetrant MethodsMethod B Applications Ideal ApplicationCastings, Extrusions, Forgings, Open immersion tanks Defect ExamplesCracks, Laps, Seams Compliance StandardsAMS 2644, ASME BPVC, ASTM E1417/E1417M, ASTM E165/E165M-18, MIL-STD-2132D SPECIFICATION COMPLIANCE • AMS2644 • ASME BPVC-V • ASTM E165/E165M-18 • ASTM E1417/E1417M • MIL-STD-2132D APPLICATIONS Defect location: open to surface Ideal for: • Use in open immersion tanks • Castings • Forgings • Extrusions Defect examples: • Cracks • Seams • Laps COMPOSITION A blend of emulsifying agents and oils.
