Magnaflux 7HF Oil-Based Visible Magnetic Particle Ink

Magnaflux 7HF is a high-sensitivity, oil-based magnetic particle ink designed for nonfluorescent (visible) wet method magnetic particle testing. It provides clear, strong indications due to the heavy buildup of highly magnetic particles, making it ideal for detecting fine and medium discontinuities on machined parts, tubing, piping, and large structures. The convenient aerosol packaging is perfect for field testing and spot inspections where bulk processing is impractical. 7HF is often used with WCP-2 white contrast paint to improve contrast and inspection sensitivity. It meets all major NDT standards and ensures corrosion protection and superior surface wetting.
