Zinc Phosphating Features

 

 

Zinc Phosphating is a conversion coating. This means that unlike electroplating where a metal coating is applied on top of the base material, during the zinc phosphating process the base metal with interact with the chemical creating a coating both outside and inside.

 

Carrier 

Zinc Phosphate is most often used as a carrier for lubricants and anti-corrosion waxes. Zinc Phosphating creates a uniform, smooth and thin film coating that enables other coatings to be applied over the phosphate layer. In this way good levels of corrosion protection are achieved whilst retaining low friction.Zinc Phosphating can act as a carrier for; lubricants, paint systems, drawing compounds, anti-friction coatings and rust inhibiting solutions.

 

Colour

The colour produced varies from light to dark grey, but Zinc Phosphating can also be dyed black to produce a glossy matte finish.

Zinc Phosphating can be applied either through immersion in a tank, or through a spray. Silchrome Plating offer medium and heavy weight immersion coatings. This
