Magnaflux Zyglo ZP-14A Water Soluble Developer

Magnaflux ZP-14A is a QPL SAE AMS 2644-qualified, water-soluble developer formulated to enhance penetrant indications during liquid penetrant inspections. The free-flowing white powder dissolves easily in water to form a stable developer solution that requires no agitation once prepared. When dry, it produces a uniform, bright white porous coating that maximizes indication contrast and visibility — and cleans up quickly with a simple water spray after inspection.

Key Features

  • Bright, Highly-Defined Indications: Uniform white porous coating maximizes contrast for clear, reliable defect detection
  • No Agitation Required: Free-flowing powder dissolves completely in water and remains stable without continuous mixing
  • Easy Water Removal: Post-inspection cleanup is fast and simple — remove with a water spray, no solvents needed
  • Even, Uniform Coverage: Consistent coating thickness ensures reliable developer performance across complex geometries
  • QPL AMS 2644 Qualified: Listed on the Qualified Products List for SAE AMS 2644, meeting aerospace and nuclear industry requirements
  • Wide Temperature Range: Reliable performance from 40°F to 120°F (4°C to 48°C)

Applications

  • Fluorescent penetrant inspection (Type 1, Form b) in automated and semi-automated lines
  • Visible dye penetrant inspection (Type 2, Form b) in shop environments
  • Aerospace and nuclear component inspection requiring AMS 2644 compliance
  • High-volume production inspection where water wash systems are available
  • Use with post-emulsifiable penetrant systems (Level 2, 3, and 4)

PREPARATION INSTRUCTIONS

Developer tank should be clean before developer bath is mixed. Fill the tank with the appropriate amount of water and slowly add the appropriate amount of developer powder to the water while stirring or agitating bath until it is completely dissolved. Once the powder is dissolved, agitation is not required to keep the developer particles suspended. To speed up bath preparation, warm water can be used, however developer bath temperature should never exceed 120°F / 48°C. Developer powder is dusty and use of a simple filter mask may be desirable during handling.

INSTRUCTIONS FOR USE

ZP-14A developer bath can be applied by immersion dip, spray or flow-on techniques, with immersion being the preferred method. If the immersion dip application is used, care must be taken to avoid transferring penetrant into the developer bath. Complete removal of surface penetrant will prolong the developer bath life. The developer bath temperature should not exceed 120°F / 48°C. If spray or flow-on techniques are used, care should be taken to avoid foaming as foam bubbles will create holes in the developer film. Use ZAF-2 antifoaming additive if necessary.

Developer bath is applied after the surface penetrant has been removed. Complete coverage of the part is essential to quality inspection. The application time is only long enough to cover the part completely. Additional contact with the developer bath may result in reduced sensitivity due to removal of penetrant from shallow discontinuities by detergent action. For best results, forced warm air drying (140ºF / 60ºC) is recommended after developer application. Once the developer is dry, the part should be removed from the dryer to prevent degrading the penetrant's visibility.

Maintenance Recommendations:

Developer bath concentration can be monitored using a hydrometer or by taking a known volume of the bath, evaporating off the water and then weighing the residue. When using a hydrometer, refer to the density concentration chart provided on the Product Data Sheet.
