Level 2 Water Washable Fluorescent Penetrant

Developed for testing rough machined surfaces, ZL-60C 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 surfaces – for clearer indications and better inspection reliability. Broad specification compliance further increase this penetrants flexibility.

ZL-60C has excellent alloy compatibility and is safe to use on most engineering and aerospace materials, including aluminum, steel, nickel and titanium.

Recommended developers are ZP-4B dry powder, SKD-S2 or ZP-9F solvent-based or ZP-5B water based.
