ZP-9F is a ready to use suspension of white developing particles in a fast drying solvent. ZP-9F produces a light white coating, which provides an excellent contrasting background for SPOTCHECK OR ZYGLO penetrant indications. ZP-9F is specially formulated to be low in sulfur and halogens and contains no chlorinated hydrocarbons. ZP-9F non aqueous developer provides maximum sensitivity through its solvent action on the penetrant at the defect site. ZP-9F is compatible with and approved for use with all MAGNAFLUX Spotcheck and Zyglo penetrants.
