BONDERITE M-ZN 952 is a nitrite accelerated tricationic phosphating process for steel, galvanized and alloy coated (Zn/Ni) steel. It generates a fine crystalline coating of manganese and nickel containing zinc phosphate. The crystalline layer has very good corrosion protection properties and is an excellent foundation for subsequent painting or organic coating. The coating weight is typically 1.8 to 2.8 g/cm² (depending on process conditions and/or substrate, the value can deviate).
