ZL-60D
Level 2 Water Washable Fluorescent Penetrant

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.

Benefits

Improve indication detection

• Makes indications stand out more by easily washing excess penetrant off with water
• Reduces background fluorescence, even on rough surfaces

Maximize application versatility

• Ideal for an extensive variety of part types due to Level 2 sensitivity
• Universal specification conformance and fast, even surface wetting

Affordable performance

• Drives value at each step of the inspection process
• Quickly apply penetrant with high surface wetting
• Easily wash off with water
• Use less penetrant over time because of lower drag-out and slower evaporation
