Product Data SheetZL-67
Level 3 Water Washable Fluorescent Penetrant
A high-sensitivity Level 3 penetrant, ZL-67 fluorescent water removeable
penetrant is designed to find smaller, finer indications in safety-criticalcomponents common to aerospace and engineering applications. ZL-67
penetrant is often used to find flaws in investment castings, jet engine
components, and highly machined surfaces.
ZL-67 is specially formulated for strong capillary action which allows it topenetrate defects quickly and bleed out into developer faster and more
completely than other penetrants for stronger, higher contrast indications
that are easier for inspectors to identify, even when the defects are very fine.
ZL-67 is listed on the QPL SAE AMS 2644 Qualified Product List and is approved for use by Pratt &Whitney.
BENEFITS
Improve indication detection••

Clear, bright, indications appear every
time due to high UV and thermal stability
Higher contrast indications form
due to strong capillary action,
making them easier to spot

Wide range of inspections•Inspect a wide range of high-value
components without fear of corrosion
or specification non-conformanceMaximize operator comfort and safety•••

Promotes better inspection quality byproviding the operator with a more
comfortable work environment
Reduces discomfort from strong odors
Exceeds all EHS requirements

More reliable, consistent inspections•

Maintain penetrant system performanceover longer periods of time thanks tolow volatility and high water tolerance
