Post-emulsifiable ZL-27A is a Level 3, high-sensitivity Type 1 penetrant designed for inspections which require maximum process control and reliability, such as safety-critical aerospace testing.
Since ZL-27A is not water soluble, there is minimal risk of this penetrant being removed from a fine or shallow defect through over-washing to provide the highest reliability of any penetrant inspection method.
ZL-27A has a high flash point and provides long tank life when used in open dip tanks, but this penetrant can also be applied in a variety of other ways, including electrostatic spray.
To remove surface ZL-27A penetrant before developer application, use ZE-4E Method B lipophilic emulsifier or ZR-10E Method D hydrophilic emulsifier can be used.
A medium sensitivity penetrant (Level 2), ZL-2C fluorescent post-emulsifiable penetrant is designed to be removed from the part surface by emulsifiers or solvent.
With a UV-A light source, indications will appear as a bright green-yellow fluorescence.
ZL-2C has a high flash point, and is designed to be used in open dip tanks.
Essential for critical component applications, ultra-high sensitivity ZL-37 post-emulsifiable penetrant is designed for detecting fine, tight discontinuities in safety-critical components, such as titanium turbine components, and in high-stress parts, such as investment castings.
This Type 1 penetrant is non-water-soluble so there is minimal risk of washing ZL-37 penetrant from a fine or shallow defect which makes this penetrant inspection the most reliable, dependable form of PT testing.
ZL-37 has a high flash point and provides long tank life when used in open dip tanks, but this penetrant can also be applied in a variety of other ways, including electrostatic spray.
ZL-37 can be removed with ZE-4B Method B lipophilic emulsifier or ZR-10C Method D hydrophilic emulsifier.
Developed for testing rough machined surfaces, ZL-60C fluorescent water-removeable penetrant is ideal for finding indications in castings, forgings, extrusions and rough surfaces.
This medium-sensitivity penetrant washes off parts quickly and easily, leaving less fluorescent background – even on rough surfaces – for clearer indications and better inspection reliability. Broad specification compliance further increase this penetrants flexibility.
ZL-60C has excellent alloy compatibility and is safe to use on most engineering and aerospace materials, including aluminum, steel, nickel and titanium.
Developed for testing rough machined surfaces, ZL-60D fluorescent water-removeable penetrant is ideal for finding indications in castings, forgings, extrusions and rough surfaces. This medium-sensitivity penetrant washes off parts quickly and easily, leaving less fluorescent background – even on rough surfaces – for clearer indications and better inspection reliability.
ZL-60D is one of the most versatile ‘work-horse’ penetrants; customers can use this one penetrant for a wide range of applications on a range of parts to find many different types of defects, including cracks, seams, laps, cold shuts, laminations and porosity. Broad specification compliance further increase this penetrants flexibility.
A high-sensitivity Level 3 penetrant, ZL-67B fluorescent water removeable penetrant is designed to find smaller, finer indications in safety-critical components common to aerospace and engineering applications. ZL-67B penetrant is often used to find flaws in investment castings, jet engine components, and highly machined surfaces.
ZL-67B is specially formulated for strong capillary action which allows it to penetrate 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.
Designed to remove excess surface penetrant, ZR-10C minimizes surface background during Method D fluorescent penetrant testing while protecting indication integrity in critical component inspections.
This Method D remover reduces fluorescent background on rough surfaces and minimizes penetrant bleed-out from hollow parts. ZR-10C works with Magnaflux PE penetrants ZL-2C Level 2, ZL-27A Level 3 and ZL-37 Level 4 for verified penetrant system reliability.
ZR-10C provides long tank life and excellent solution consistency for dependable, long-lasting performance in a variety of applications.
