Penetrant, ZL-19, Type: Fluorescent; Container Size: 5 gal; Container Type: Pail; Color: Bright Green-Yellow

A water-removeable Level 1 penetrant, ZL-19 is designed for use on
rough or unmachined surfaces such as castings and forgings to find
larger discontinuities in non-safety critical components. It is ideal for
inspecting automotive and general industrial components such as
engine cylinder blocks, power train components, rocker arms, pistons, steering knuckles, etc.
ZL-19 washes off parts with ease, leaving less background for clearer
indications – even on rough surfaces. The quick rinsing reduces water usage in the inspection process which helps users reduce their over-all cost per part by reducing penetrant loss through drag-out, speeding up the washing and inspection process, and cutting rinse
water costs.

ZL-19 can be used with ZP-4D dry powder developer, with ZP-5B water suspendible developer in an
agitated tank or with ZP-9F non-aqueous developer. With a UV-A light source, indications will appear as
a bright green-yellow fluorescence.

ZL-19 is listed on the QPL SAE AMS 2644 Qualified Product List.
