BONDERITE® M-ZN 210 is a zinc-phosphate metal pretreatment solution that effectively cleans and prepares iron and steel metal surfaces prior to the application of stains, oils, waxes, or paints. It produces a uniform non-metallic zinc-phosphate coating capable of reaching threaded pieces and articles with small holes or recesses to protect surfaces from corrosion, in addition to promoting the adherence of these final finishes due to its absorptive nature. BONDERITE® M-ZN 210 also helps minimize the buildup of scale and sludge o. surfaces.
