ZINC PHOSPHATE COATING-MANGANESE PHOSPHATE COATING WITH DRY-TO-THE TOUCH OILING

Phosphate coatings are used on ferrous metals both as a finishing layer and as a foundation for subsequent surface coatings.
PHOSPHATE COATING

ZINC PHOSPHATE COATING 

Zinc phosphate coatings are mainly used for corrosion resistance and are an excellent pre-painting base improving performance and adhesion of paints or surface finishings.The deposited phosphate layer adheres to the substrate also through sandblasting processes; its absorption power allows it to be impregnated with lubricating oils and waxes thus improving corrosion resistance or cold drawing/extrusion.The phosphate coating is velvety in appearance and varies in colour from black to grey; the weight of the deposited phosphate layer is included between 2 and 35 g/m2.
PHOSPHATE COATING

MANGANESE PHOSPHATE COATING

Manganese phosphate coatings are mainly used to facilitate lubrication by reducing friction between reciprocal sliding surfaces. Being a sacrificial treatment, after a first phase of running-in, perfectly specular surfaces are obtained. Similarly, to zinc phosphate coating, also manganese phosphate coating can be impregnated with lubricating oils and waxes thus improving corrosion resistance.
The phosphate coating is velvety in appearance and varies in colour from dark grey and black; the weight of the deposited phosphate layer is included between 7 and 30 g/m2.

MAIN PROPERTIES

  • Corrosion resistance
  • Wear resistance of moving mechanical parts
