Product information

Magnaflux ZL-15B Level 1/2 Water Washable Fluorescent Penetrant

ZL-15B water washable penetrant is a low-sensitivity penetrant that features excellent wash-ability. 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.

Instructions for use

Pre-clean the test part and allow to dry. The surface must be free from oil, grease and any other contaminant.

Apply the penetrant by immersion dip, brush, flow on, conventional or electrostatic spray. The test area must be completely covered with penetrant.

Allow contact time of 2 – 5 minutes minimum. 10 minutes should be adequate for most situations, although specific process specifications may require longer – check the controlling process specification (where applicable).

Remove excess ZL-15b penetrant by thoroughly spraying the test part with clean water at 10°C – 40°C. This should be carried out under a UV(A) source so you can monitor the penetrant removal.

Dry the test part by placing in a controlled recirculating warm air dryer at a temperature of 50°C – 70°C.

Apply a developer to maximise the sensitivity of the penetrant and to provide a white contrasting background. There are three types of suitable developer:

• Dry powder: Free-flowing, lightweight powders which are applied to the dry component by powder storm, dusting, electrostatic spray or puffer.
• Solvent-based: Quick-drying materials which are applied to the dry component by spraying.
• Aqueous or water-based: Apply before drying by dipping or spraying. Note: to maximise penetrant sensitivity, do NOT leave parts in aqueous developers for any length of time.

Inspect your test part using a suitable UV source. Any defect indications will fluoresce a bright green-yellow when exposed UV(A) light at a peak wavelength of 365 nm.

If required, you can clean your test part after inspection. Developer residues can be removed either by wiping with a cloth or by a water and detergent wash. ZL-15B Penetrant residues can be removed by vapour degreasing or solvent soak.
