Description
Zyglo ZL-27A Post Emulsifiable Fluorescent Penetrant designed to be impervious to water to protect it from over washing and permit more penetrant to remain in discontinuities for improved detection of small defects. It and other post emulsifiable penetrants require the application of a lipophilic or hydrophilic emulsifier to render them washable with water. – Level 3 sensitivity
Post-emulsifiable fluorescent penetrants are used for a wide range of sensitive applications and are formulated to be impervious to water to assure against being over-washed from defects. They require the application of a lipophilic emulsifier or a hydrophilic emulsifier to render them washable with water and meet OSHA requirements for Class III B liquids due to their high flash point, allowing them to be used in open dip tanks.
Zyglo post-emulsifiable fluorescent penetrants fluoresce a bright greenish-yellow color under ultraviolet radiation. Use of a black light source with a peak wavelength of 365nm is required.
