Magnaflux Zyglo ZP-9F Developer, MIL-STD-2132

Magnaflux Zyglo ZP-9F is a solvent-based, non-aqueous developer used with fluorescent and visible liquid penetrant inspection (LPI) processes. ZP-9F produces a thin, opaque white coating that provides strong background contrast for identifying surface-breaking indications such as cracks, seams, and porosity.

Designed for nondestructive testing applications, ZP-9F is listed on the QPL SAE AMS 2644 Qualified Product List and is qualified for Type 1 fluorescent and Type 2 visible penetrant testing in Form d and Form e developer applications. Magnaflux also lists ZP-9F for use with MIL-STD-2132, ASTM E1417, ASTM E165, AMS 2644, AMS 2647, and other industry specifications. Always verify the applicable specification, revision, and process requirements for your specific inspection procedure before use.

ZP-9F for Liquid Penetrant Inspection

ZP-9F is applied after excess penetrant has been removed and the inspection surface has been properly prepared. The developer forms a thin white coating that creates contrast between the background and penetrant indications. With visible penetrants, relevant indications appear as contrasting red lines or spots. With fluorescent penetrants, relevant indications fluoresce under an appropriate UV-A inspection light.

Magnaflux recommends applying ZP-9F in a thin, even layer. Excessive application can contribute to bleeding or running of indications, while insufficient developer coverage can slow indication development and potentially affect inspection sensitivity. Follow the penetrant manufacturer's instructions and the governing inspection procedure for application, dwell, inspection, and removal requirements.

Magnaflux ZP-9F Specifications & Compliance

Typical ZP-9F Applications

Magnaflux ZP-9F is used in liquid penetrant inspection of components and assemblies where surface-breaking discontinuities need to be detected. Typical applications include:

• Aircraft and aerospace components
• Welds
• Castings
• Forgings
• Pressure vessels
• Leak testing
• Maintenance and general industrial inspection
• Metal components requiring nondestructive surface inspection

ZP-9F Application Guidelines

Before applying developer, the inspection surface should be clean, dry, and free of excess penetrant. Magnaflux recommends applying ZP-9F by spraying only, using either the aerosol package or a conventional spray gun. The developer should be applied as a thin, uniform coating that just wets the surface.

ZP-9F should be agitated or shaken during use to maintain a uniform suspension of developer particles. Refer to the current Magnaflux Product Data Sheet, Safety Data Sheet, and the applicable inspection procedure for complete handling and application instructions.
