ZL-67B

Zyglo® ZL-67B is a high sensitivity water washable fluorescent penetrant, used for a wide range of applications.

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.
