Manganese Phosphate

SCOPE:                               

HAMBOND-ZM is designed to produce heavy manganese phosphate coating on iron and steel surfaces at ****5 °C. The coating conforms with the British Standard ***9 . In practice, the weights of coatings are usually in the range *0 to *0g/m2. Such coatings, when sealed with oil, greases or wax provide excellent protection against corrosion.

PROCESS :

• The job to be phosphated is first degreased ,rinsed and then immersed in the chemical bath for *5 to *0  minutes at room temperature.
•  After Phosphating the metal surface is rinsed with hot clean water, dried and then dipped in oil.
•  The oil is then drained and the metal surface is then ready for storage.

PROPERTIES

• Permits rapid break-in of moving parts without scuffing or welding by preventing metal to metal contact between the bearing surfaces.
• Increases lubrication of treated surfaces due to the oil-absorptive coating.
• Removes light metal scratches remaining from machining operations.
• Retards corrosion.

ADVANTAGES

• The HAMBOND-ZM can be used to phosphatise iron and steel surfaces at an ambient temperature of *0 to *0 °C.
• Cost of phosphating at ambient temperature is reported to be *0% less than the conventional Manganese phosphating process operating at higher temperature due to savings in the energy consumption.
• By using HAMBOND-ZM the chemical consumption is reported to be *0 to *0 percent less then the conventional manganese phosphating process operation at higher temperature.
• Manganese phosphate coatings are heavier and courser than zinc phosphate.
• It offers execellent wear resistance and reduces wear and tear during metal to metal contact.
• Manganese phosphate is ideal for service applications and for the rapid break-in of new parts.
• It is anti-galling and will not flake or peel off.
