ZR-10E
Hydrophilic Emulsifier
Hydrophilic emulsifier ZR-10E is designed to reduce fluorescentbackground from penetrants on rough surfaces, as well as reducing
bleed-out of penetrant from hollow parts. It yields reliable andreproducible test results from post-emulsifier penetrants.
ZR-10E is listed on the QPL SAE AMS 2644 Qualified Product List and isapproved for use by Pratt & Whitney.
BENEFITS
Maximize penetrant inspection process control• PE penetrant system is less susceptible
to human error since ZR-10E only workswith rinse water to remove excess surface
penetrant• Tested and confirmed per AMS 2644 towork with Magnaflux PE penetrants forverified penetrant system reliability• Maintains solution consistency for
dependable performance with minimal
agitation
Wide range of inspections• Flexible to work with many types ofequipment and application methods• Inspect a wide range of high-value
components without fear of corrosion or
specification non-conformance• Meets all major industry and NDTspecification requirements, including
Aerospace Prime and OEM specs, AMS
2644 and ISO 3452

INSTRUCTIONS FOR USE
ZR-10E concentrate is diluted in water before use
and can be applied by spray or immersion dip. A
water spray pre-rinse step is recommended before
applying a hydrophilic emulsifier like ZR-10E inorder to reduce the penetrant film. For immersion
method application, this also helps by prolonging
the emulsifier bath life by reducing the amount ofpenetrant contaminating the bath.
If the spray method is used, an injector or metering
pump should be used to control the concentration.
The general spray concentration range is 1 to 5%
emulsifier. Spray removal should be performed
under UV light to control removal of penetrant fromthe surface.
If the immersion dip method is employed thegeneral concentration range is 20% emulsifier for
optimal remover activity, bath life, economics andprocess rate. The part is immersed in the emulsifierbath, which is gently agitated by mechanical or airmeans. The length of time the part is in the bath willvary with the concentration of the bath, the type
penetrant being used, specification requirements
and the desired results. At the recommended
concentration, the immersion contact time generally
ranges between 30 and 180 seconds. The
immersion dip is followed by a clean water rinse toremove any emulsifier/penetrant residue.
Maintenance Recommendations:Hydrophilic emulsifier bath concentration can bemonitored using a refractometer and concentration
chart. To create a ZR-10E concentration chart, selectthree to five accurately known samples (e.g. 5,10, 15, 20, 25% ZR-10E) which have been carefullymeasured and mixed. Take readings of the known
samples using the hand-held refractometer. Plot achart with the refractometer readings on the verticaly-axis and the known percentage of ZR-10E values
on the horizontal x-axis. The water content of thebath can also be determined using the proceduredescribed in ASTM D-95.
