ZN - PHOSPHATE

TECHNICAL CHARACTERISTICS OF ZINC-PHOSPHATE

In manganese-phosphate process, the weight of phosphate varies by the chemicals used and the working conditions.
The weight of phosphate ;

•    For  painting ...................................................... 2-6  (gram/m²)
•    For cold-forming and protection of surface....... 5-15 (gram/m²).

In protective phosphate coating, the corrosion resistance of the material varies by the characteristic of the lubricants, emulsion or wax impregnated by phosphate crystals.
The weight of phosphate for Fe-Phosphating is 0.2-1.2 gr/m².  Fe-phosphate coated parts are used indoor places.

Degreasing and derusting  processes, which must be performed before phosphate coating process, are very important. If these processes are not properly performed, the benefits of phosphate coating would not be as desired.

There is two differences application techniques.

•    Spraying system
•    Dipping system
