SKL-WP - Magnaflux Spotcheck SKL-WP Water Washable Red Dye Penetrant Aerosol

Professional Weld Inspection with Spotcheck SKL-WP

For professional welders and inspectors, ensuring the integrity of a weld is paramount. The Magnaflux Spotcheck SKL-WP Water Washable Penetrant is an essential tool in the arsenal of any certified welding inspector (CWI) or fabrication shop. This 16oz aerosol can delivers a high-performance red dye penetrant that is specifically engineered to locate surface-breaking defects such as cracks, porosity, and laps in welds and heat-affected zones.

The SKL-WP distinguishes itself with its water-washable properties. In the liquid penetrant inspection (LPI) process, removing excess penetrant without removing the penetrant from the defect is critical. With SKL-WP, the excess dye on the surface can be easily removed with a coarse water spray, eliminating the tedious step of wiping with solvent-soaked rags. This is ideal for inspecting complex weld beads or rough castings where lint from rags might snag or where solvent wiping is impractical. Once the surface is rinsed and dried, the application of a developer (such as SKD-S2) draws the remaining penetrant out of the cracks, revealing vivid red indications.

Designed for high sensitivity, this penetrant works effectively on aluminum, steel, stainless steel, and ceramics. It is an excellent choice for high-volume production environments or field applications where speed and ease of use are required. The aerosol format ensures a consistent, even application without the need for brushes or bulk spray equipment. By incorporating SKL-WP into your quality control procedures, you can confidently detect discontinuities before they become critical failures.

Application Steps:

• Pre-clean: Ensure the part is clean and dry using a cleaner like SKC-S.
• Apply Penetrant: Spray SKL-WP and allow a dwell time (typically 10-30 minutes).
• Rinse: Wash excess penetrant away with water.
• Develop: Apply a developer to draw out the indication.
• Inspect: Look for red lines or spots indicating defects.
