PENETRANT: FLUORESCENT, MAGNAFLUX ZL-37,LEVEL 4 | Magnaflux Corp

Zyglo ZL-37 is designed to be impervious to water to protect it from overwashingand to allow more penetrant to remain in discontinuities for improved detection of small defects. It and other post emulsifiable penetrants require the application of a lipophilic or hydrophilic emulsifier to render them washable with water.Zyglo ZL-37 fluoresces bright greenish-yellow under an ultraviolet light sourcewith a peak wavelength of 365 nm. It possesses a high flash point and meets OSHA requirements for Class III B liquids allowing it to be used in open dip tanks.Specification Compliance: AMS 2644, AECL, ASME B & PV Code Sec. V, ASTM E1417, MIL-STD-2132, ASTM E165, MIL-STD-271, Boeing BAC 5423 PSD 6-46 or 8-4, AECL, Boeing PS 21202.Applications: Zyglo ZL-37 is ideal for titanium turbine components, investmentcastings, and other high stress critical components where detection of fine, tight discontinuities is required.Classification: Type 1, Method B Penetrant when using ZE-4B emulsifier.Type 1, Method D Penetrant when using ZR-10B (20%) remover.Penetrant Sensitivity Level: Level 4 - Ultra High Sensitivity.
