ZL-60C

Level 2 Water Washable Fluorescent Penetrant

ZL‑60C is a Level 2 water-washable fluorescent penetrant developed for non-destructive testing on rough machined surfaces like castings, forgings, extrusions, and weldments. It offers medium sensitivity, washes off readily to minimize background fluorescence, and is compatible with a wide variety of aerospace and engineering alloys.

Features

Medium sensitivity (Level 2): Suitable for a broad range of surface defects on rough finishes.
Water-washable: Efficient removal of excess penetrant, reducing background and inspection time.
Excellent wetting: Rapid and uniform coverage across surfaces.
Bright fluorescence: Emits green‑yellow glow under UV-A light for clear defect visibility.
Alloy-compatible: Safe for aluminum, steel, nickel, titanium, and aerospace-grade materials.
Economic: Lower drag-out and evaporation, minimizing waste.

Applications

Inspection of castings, forgings, extrusions, welds, and machined parts.
Detection of surface discontinuities such as cracks, seams, laps, porosity, delaminations, and cold shuts.
Ideal for aerospace, automotive, and general engineering inspections.
