ZE-4B

Lipophilic Emulsifier

ZE-4B is a Method B lipophilic emulsifier formulated for use with post-emulsifiable penetrants such as ZL-2C, ZL-27A, and ZL-37. It effectively diffuses into the penetrant to clear it from the surface of the part being inspected, facilitating the removal of excess penetrant during the inspection process.

Features

Low Volatility: Ensures safe use in open immersion tanks.
High Flash Point: Enhances safety during application.
Fast Acting: Reduces processing times by quickly removing excess penetrant.
Ready to Use: Supplied in a ready-to-use form, eliminating the need for dilution.
Safe on Aerospace Alloys: Compatible with materials such as aluminium, steel, nickel, and titanium.

Applications

Industries: Aerospace, automotive, manufacturing, and maintenance.
Components: Castings, forgings, extrusions, and other parts requiring non-destructive testing.
Defect Detection: Effective in identifying surface discontinuities such as cracks, seams, and laps.
