Zyglo® 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.
Zyglo® ZL-27A 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-2C is typically used on castings, forgings, extrusions and rough and machined surfaces to find cracks, seams, laps, laminations and porosity.
