Product Information
ZL-27A’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.
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 3 High Sensitivity
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: Zyglo® ZL-27A is typically used on castings, forgings, extrusions and rough and machined surfaces to find cracks, seams, laps, laminations and porosity.
