| Magnaflux ZL-4C Zyglo Water Base Fluorescent Penetrant - 5 Gal PailAvailability: Ready to Ship in 3 Business Days International Orders  Part#: 01-3137-40 by Magnaflux |
This biodegradable, fluorescent penetrant is water-based, meaning it is soluble in water and can be diluted infinitely (but generally is used as supplied, or diluted from 1:1 to 1:2 in water). ZL-4C contains water, fluorescent dye, liquid emulsifying agents, but has no petroleum base solvents and no corrosion inhibitors. When placed under ultraviolet radiation of 365 nanometers, it fluoresces a bright greenish-yellow color to aid in leak detection. The Magnaflux ZB-100F fan-cooled black light is recommended. ZL-4C is used in applications where petroleum solvents are not desired, such as on plastics. It can also be used on ceramics. Overall Rating for Magnaflux ZL-4C Zyglo Water Base Fluorescent Penetrant - 5 Gal Pail
Method of Application Surface area to be tested must be clean and dry before penetrant application. ZL-4C can be applied by dipping, brushing, flowing on, or spraying. ZL-4C can be diluted with water to lower its viscosity, making spraying easier. When diluted, it will penetrate through leaks faster than when undiluted. Penetration/Dwell Time For conventional penetrant applications allow 2 to 15 minutes penetration time. For leak testing, apply penetrant to one side of test area, apply developer to the opposite side and allow 15 to 30 minutes penetration time before inspecting under black light. Penetrant Removal ZL-4C is easily removed by water rinsing; care must be taken to avoid over removal of penetrant from discontinuities. Recommended Developers Aqueous developers are not recommended with ZL-4C as they tend to wash the penetrant out of the discontinuities. Dry powder developer (ZP-4B Dry Powder Developer) is applied after the test surface has been dried. Coverage 1 gallon covers approximately 800 square feet.
