Containing no oil or solvents, Compound RP-99S from Madison Chemical is a water-based rust preventive designed for use on ferrous and copper metals. It can be applied to previously cleaned parts by immersion, manual spray or recirculated spray methods, and is said to leave a nearly invisible, dry-to-the-touch film that provides short-term indoor-storage protection that lasts at least four weeks or longer, depending on concentration.
For most applications, the compound is used at 2-10 percent by volume in water varied from 70°F to 160°F. Heating the solution will lessen the time required for drying and may improve overall protection results, the company says. Concentrations ranging to 15 percent may be used for longer rust protection time.
The product also can be used as a deburring compound in barrel and vibratory equipment for mass finishing operations, providing detergency to keep mass finishing media clean and removing 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. It is used at 1-5 percent by volume in water for mass finishing applications.
E-coat can produce uniform finishes with excellent coverage and outstanding corrosion resistance.
