Zylglo® ZL-37 Post Emulsifiable Fluorescent Penetrant by Magnaflux®

Zyglo® ZL-37 (Level 4) Post Emulsifiable Fluorescent Penetrant

Zyglo® ZL-37’s formulation has been designed to be impervious to water to protect it from over washing and permit 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 penetrant meets OSHA requirements for Class III B liquids due to its high flash point and can be used in open dip tanks.

Specifications Compliance: AMS-2644, ASTM E 1417, MIL-STD-271, ASME B & PV Code, Sec. V, MIL-STD-2132, AECL, ASTM E 165, Boeing PS-21202

Applications:ZL-37 is ideal for titanium turbine components, investment castings and other high stress critical components where detection of fine, tight discontinuities is required.

Classification:Type 1, Method B Penetrant when using ZE-4E emulsifier. Type 1, Method D Penetrant when using ZR-10B (20%) remover.

Sensitivity Level: Level 4 - Ultra-High Sensitivity
