Magnaflux Fluorescent Water Washable Penetrant

Magnaflux Fluorescent Water Washable Penetrant

ZYGLO Penetrants at Sensitivity Levels 1/2 - 4

Overview

Fluorescent materials are used with the Liquid Penetrant inspection method to locate surface flaws in non-porous parts. Available in liquid form (ZL-60D Aerosols have been discontinued). Choose from five sensitivity levels to satisfy military, industry or company specifications. ZYGLO formulas offer improved sensitivity, brightness, and resistance to over washing.

ZL-15B, Level 1/2, Methods A/C

ZL-15B water washable penetrant is a low-sensitivity penetrant that features excellent washability. It is used to find open surface flaws such as cracks and porosity in seams, laps, cold shuts, and laminations on castings, forgings, extrusions, and parts with rough surfaces. It can be developed with ZP-4B dry powder developer, with ZP-5B water suspendible developer in an agitated tank or with ZP-9F non-aqueous developer. With a UV-A light source, like the EV6000, indications will appear as a bright green-yellow fluorescence. ZL-15B is listed on the QPL SAE AMS 2644 Qualified Product List.

Features

  • Level 1/2 Low/Medium Sensitivity
  • Methods A/C - Water Washable/Solvent-Removable
  • Excellent washability
  • QPL approved

ZL-19, Level 1

A water-removeable Level 1 penetrant, ZL-19 is designed for use on rough or unmachined surfaces such as castings and forgings to find larger discontinuities in non-safety critical components. It is ideal for inspecting automotive and general industrial components such as engine cylinder blocks, power train components, rocker arms, pistons, steering knuckles, etc. ZL-19 washes off parts with ease, leaving less background for clearer indications – even on rough surfaces. The quick rinsing reduces water usage in the inspection process, and the rinse water is easily treatable for simpler disposal. This economical fluorescent penetrant helps users reduce their over-all cost per part by reducing penetrant loss through drag-out, speeding up the washing and inspection process, and cutting rinse water costs. ZL-19 can be used with ZP-4B dry powder developer, with ZP-5B water suspendible developer in an agitated tank or with ZP-9F non-aqueous developer. With a UV-A light source, indications will appear as a bright green-yellow fluorescence. ZL-19 is listed on the QPL SAE AMS 2644 Qualified Product List.

Benefits

Increase Indication Detection on Cast Parts & Rough Surfaces

  • Increase detection of defects in cast parts, such as hot tears, laps, or cold shuts
  • Indications stand out more because of reduced background fluorescence, even on rough cast surfaces

Speed up your Inspection Process

  • Quickly apply and remove penetrant due to high surface wetting and easy washability
  • ZL-19 is spray-friendly and will not clog nozzles in automated lines, for less maintenance downtime

Performance Value

  • Use less penetrant per part, thanks to lower drag out
  • Penetrant can be reused from the dwell cycle, so more of it stays in your tank instead of getting carried away on parts

Features

  • Level 1 low sensitivity 
  • Methods A/C - Water washable/Solvent-Removable
  • Excellent rough surface washability
  • Bright, high contrast indications
  • Clean rinsing on cast parts
  • Won’t clog spray nozzles in automated systems
  • Good surface wetting
  • High flash point
  • Easy washability
  • Less time to rinse
  • Use less penetrant per part

ZL-60D, Level 2, Methods A/C

Developed for testing rough machined surfaces, ZL-60D fluorescent water-removeable penetrant is ideal for finding indications in castings, forgings, extrusions and rough surfaces. This medium-sensitivity penetrant washes off parts quickly and easily, leaving less fluorescent background – even on rough surface – for clearer indications and better inspection reliability. ZL-60D is one of the most versatile “work-horse” penetrants, customers can use this one penetrant for a wide range of applications on a range of parts to find many different types of defects, including cracks, seams, laps, cold shuts, laminations and porosity. Broad specification compliance further increase this penetrants flexibility. ZL-60D has excellent alloy compatibility and is safe to use on most engineering and aerospace materials, including aluminum, steel, nickel and titanium. ZL-60D is listed on the QPL SAE AMS 2644 Qualified Product List and is approved for use by Pratt & Whitney.

ZL-67, Level 3, Methods A/C

A high-sensitivity Level 3 penetrant, ZL-67 fluorescent water removeable penetrant is designed to find smaller, finer indications in safety-critical components common to aerospace and engineering applications. ZL-67 penetrant is often used to find flaws in investment castings, jet engine components, and highly machined surfaces. ZL-67 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. ZL-67 is listed on the QPL SAE AMS 2644 Qualified Product List and is approved for use by Pratt & Whitney.

Benefits
