Magnaflux® ZYGLO® ZL-37A Level 4 Post Emulsifiable Fluorescent Penetrant, 55 GL | 01-3188-45
ZL-37 post-emulsifiable penetrant is essential for critical component applications. Ultra-high sensitivity ZYGLO ZL-37 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.
