Magnaflux Dry Powder Developer
ZP-4B is a free flowing, white, fluffy powder used as a high sensitivity dry powder developer for penetrant inspection. It is supplied ready to use and forms a thin film on parts which enables it to enhance indications of ultra-fine discontinuities. ZP-4B is listed on the QPL SAE AMS 2644 Qualified Product List and is approved for use by Pratt & Whitney.
ZP-4B pairs perfectly with ZL-4C, Magnaflux's water-based penetrant, making it ideal for inspecting plastics.
