Water Soluble Developer

ZP-14A is a water-soluble developer for the enhancing penetrant indications during liquid penetrant inspections. It produces a uniform white porous coating when dry which is easily removed in post inspection cleaning by a water spray. Advantages include bright and highly defined indications, and can be cleaned with water.

This white free-flowing powder dissolves in water to form a developer solution and does not require agitation once the developer bath is prepared. ZP-14A is recommended for use with Level 2 ZL-2C, Level 3 ZL-27A and Level 4 ZL-37 post-emulsifiable penetrants.

ZP-14A is listed on the QPL SAE AMS 2644 Qualified Product List.
