MFX01-5352-78 - Magnaflux SKD-S2 Spotcheck Developer Spray 16oz

High-Performance Solvent Developer for NDT Inspection

The Magnaflux SKD-S2 is a ready-to-use, solvent-based developer designed to work in conjunction with the Spotcheck family of dye penetrants. Engineered for critical non-destructive testing (NDT) applications, this developer creates a bright, opaque white background that significantly enhances the visibility of red penetrant indications. By providing a high-contrast backdrop, SKD-S2 ensures that even the smallest discontinuities, such as hairline cracks, porosity, and laps, are easily detectable by inspectors.

Formulated with a blend of white developing particles suspended in a fast-drying solvent, SKD-S2 is optimized for efficiency. Upon application, the solvent evaporates rapidly, leaving a thin, uniform film on the test surface. This film acts as a blotting agent, utilizing capillary action to draw the penetrant out of surface-breaking defects and spreading it on the surface for clear visualization. The product is specifically formulated to be low in sulfur and halogens, making it safe for use on a wide variety of materials, including stainless steel, titanium, and nickel alloys, where corrosion from impurities is a concern.

SKD-S2 is fully compliant with major industry standards, including AMS 2644, ASTM E165, and ASME Boiler and Pressure Vessel Code Section V. It contains no chlorinated hydrocarbons, reducing health and environmental risks associated with older NDT formulations. Whether used in aerospace, automotive, or general industrial manufacturing, this developer provides the reliability and sensitivity required for rigorous quality control processes.

Key Technical Benefits

• Rapid Evaporation: The solvent carrier dries quickly, allowing for faster inspection cycles without compromising sensitivity.
• Enhanced Sensitivity: The fine particle size creates a smooth, matte white finish that maximizes the contrast against vibrant red penetrants.
• Broad Compatibility: Safe for use on most engineering alloys and compatible with both water-washable and solvent-removable penetrants.
