Manganese phosphate coating can be applied
to many metal parts and equipment such as drill bits and drilling elements, nuts and screws, tooling tools. It is a type of coating that takes place in military
standards in the defense industry (MIL-DTL-16232-G). Manganese phosphate coating is also made on many parts in compressors, oil pumps and hydraulic systems.
Manganese phosphate coating is applied by dipping. Its color is more close to black. Activation is used just before manganese phosphating. It is important to use activation to obtain a coating with uniform and fine crystal structure that meets corrosion resistance standarts. Activation is also required for hard steel parts that are difficult to coat.
One-component product for iron, steel and cast parts used by dipping method. Depending on use of activation, the coating weight is 15 - 25 g/m2 and the coating thickness is 5 - 25 microns. It has the advantage of working at low temperatures when used with activation pre-rinse. It provides high corrosion resistance in accordance with the standards.
It is a slightly alkaline product in powder form that is used just before the manganese phosphating treatment. It makes it possible to coat hardened steel materials that are difficult to coat. Provides fine crystalline coating with low thickness to meet the standards requiring high corrosion resistance.
Manganese phosphate coating product that can be used in low concentrations compared to standard products suitable for iron, steel and casting. It is applied by dipping. Provides coating in the range of 10 - 20 g/m2. Higher corrosion resistance coating is obtained with the use of activation.
It is an acid regulating additive product used in manganese phosphate coating baths. The total acid/free acid balance of the working bath must be ideal for problem-free continous working. It is used to correct the acid imbalances in the phosphating solution depending on the properties of the coated parts and working temperature.
