Magnaflux ZL-27A is a water-washable, fluorescent penetrant designed for highly sensitive liquid penetrant inspection (LPI) applications. Classified as a Level 3 sensitivity penetrant per AMS 2644 and ISO 3452-2 standards, ZL-27A provides excellent discontinuity detection on critical components such as turbine blades, aerospace structures, and precision parts. It offers superior brightness and defect resolution under UV light and is suitable for use in both aerospace and industrial inspection settings. ZL-27A is ideal for applications requiring maximum flaw detection performance with ease of post-penetrant removal.
