형광침투탐상제(MAGNAFLUX)Post EmulsifiableFluorescen Penetrant

ZL-37 Level 4 Post Emulsifiable Fluorescent Penetrant

Essential for critical component applications, ultra-high sensitivity (Level 4) ZL-37 fluorescent post-emulsifiable penetrant is designed for detecting fine, tight discontinuities. Parts common for this testing procedure include titanium turbine components, and high-stress critical components such as investment castings. With a UV-A light source, indications will appear as a bright green-yellow fluorescence. ZL-37 has a high flash point, and is designed to be used in open dip tanks.

Both Method B lipophilic emulsifier ZE-4E and Method D hydrophilic emulsifier ZR-10E can be used to remove surface ZL-37 penetrant. Developers can be ZP-4B dry powder developer, ZP-14A water soluble developer in a non-agitated tank, ZP-5B water suspendible developer in an agitated tank, or ZP-9F non-aqueous developer.

ZL-37 is listed on the QPL SAE AMS 2644 Qualified Product List and is approved for use by Pratt & Whitney.

Benefits

• Bright, high-contrast indications
• Resists over-washing

ZL-27A Level 3 Post Emulsifiable Fluorescent Penetrant

Post-emulsifiable ZL-27A penetrant is a high-sensitivity penetrant designed for inspection with the use of an emulsifier to remove surface penetrant. Both Method B lipophilic emulsifier ZE-4E and Method D hydrophilic emulsifier ZR-10E can be used to remove surface ZL-27A penetrant before developer application. Developers can be ZP-4B dry powder developer, ZP-14A water soluble developer in a non-agitated tank, ZP-5B water suspendible developer in an agitated tank or ZP-9F non-aqueous developer. With a UV-A light source, flaw indications will appear as a bright green-yellow fluorescence. ZL-27A has a high flash point, and is designed to be used in open dip tanks.

ZL-27A is listed on the QPL SAE AMS 2644 Qualified Product List and is approved for use by Pratt & Whitney.

Benefits

• Bright indications
• Resists over removal
• High flash point
• QPL SAE AMS 2644 Qualified Product List
• Approved for use by Pratt & Whitney
