ZP-9F

Solvent- based Developer

ZP-9F is a non-aqueous, ready-to-use developer formulated with organic particles suspended in a fast-drying solvent. It produces a bright white, opaque coating that enhances the visibility of surface discontinuities during both fluorescent and visible penetrant inspections. This developer is particularly effective in applications requiring high sensitivity and is listed on the QPL SAE AMS 2644 Qualified Product List.

Features

High Sensitivity: Provides excellent background contrast, enhancing the visibility of surface defects.
Fast Drying: Quickly dries to form a matte, opaque coating, reducing inspection time.
Ready-to-Use: Convenient formula that requires no mixing or dilution.
Low Toxiity: Very low toxicity, ensuring a safer working environment.
Easy Application: Can be applied via aerosol or conventional spray gun.
Easy Cleanup: Developer residue can be removed by wiping with a cloth or using a water and detergent wash.
Vesatile Compatibility: Suitable for use with a variety of Type 1 and Type 2 penetrants without the need for measuring or diluting.

Applications

Industries: Aerospace, automotive, construction, maintenance, marine, petroleum pipelines, power plants, and general metalwork.
Components: Welds, castings, forgings, leak testing, pressure vessels, aircraft, off-highway equipment, and farm equipment.
Defect Detection: Effective in identifying cracks, seams, and porosity.
