Rust preventive protects ferrous and copper metals in short-term storage

Madison Chemical offers Compound RP-99S, a water-based rust preventive for use on ferrous and copper metals. Applied to previously cleaned parts by immersion, manual spray, or recirculated spray methods, the product leaves a nearly invisible, dry-to-the-touch film that provides short-term indoor storage protection for treated parts that lasts up to four weeks or longer, depending on concentration. It contains no oil or solvent.

The rust preventive also can be used as a deburring compound in barrel and vibratory equipment for mass finishing operations. It provides detergency to keep mass finishing media clean and remove light oil and metal chips from parts. It also promotes the sinking of suspended particles and floating of oil for increased tank life of recirculated solutions.
