Magnaflux Spotcheck SKL-4C Water-Based Dual-Purpose Penetrant
Magnaflux SKL-4C is a specially formulated water-based, water-washable penetrant engineered for chemically sensitive plastic parts and effective leak detection. Its unique dual-purpose formula produces dark purple-red indications under visible light and fluorescent orange indications under UV light — giving inspectors maximum flexibility in a single product. Dilutable with water (recommended 1:1 ratio for general use), SKL-4C simplifies application and cleanup without sacrificing sensitivity.
Key Features
- Dual-Purpose Visibility: Visible red-dye indications under white light and fluorescent orange under UV — one penetrant for two inspection modes
- Water-Based & Water Washable: Easy application, cleanup, and disposal; no harsh solvents required
- Plastic-Safe Formula: Specifically designed for chemically sensitive substrates including plastics and composites
- Leak Detection Capable: Effective for both surface-breaking defect detection and leak testing applications
- Dilutable: Can be diluted with water at a 1:1 ratio for general applications, extending product yield
- Wide Temperature Range: Performs reliably from 40°F to 125°F (4°C to 52°C)
Applications
- Penetrant testing of chemically sensitive plastic and composite components
- Leak detection on assemblies, pressure vessels, and fittings
- Visible light inspection (Type 2) in shop and field environments
- UV fluorescent inspection where dual-mode capability is required
- General NDT quality control in manufacturing and maintenance
