Post Emulsifiable Fluorescent Penetrant
ZL-27A LEVEL-3 :

ZL-27A EMULSIFIABLE PENETRANT TYPE 1 is developed for safety-critical aerospace process testing with more reliability.
There is less risk of penetrant being removed from shallow and fine defects through over-washing because it is not soluble in water. It provides strong reliability to all types of penetration methods.
LEVEL-3 ZL-27A has a high flash point and supplies elongate
tank life when utilized in open dip tanks, this penetration is also applicable in a variety of different ways, like electrostatic spray.
Use ZE-4E Method B lipophilic emulsifier or ZR-10E Method D hydrophilic emulsifier before developer application to clear surface ZL-27A penetrant.


The bright indication can easily be detected because of UV
Thermal stability for little flaws and discontinuities
PE penetrant system is less liable to human error since only the surface penetrant is removed in the final rinse stage.
