PRE-TREATMENT PROCESS FOR FERROUS

1. DEGREASING This stage removes oil, grease, dirt and other dust particles to give a clean, surface for next stage in the process (for ferrous &Non Ferrous) Chemical base: Alkaline

2. WATER RINSE To remove the chemical from the earlier stage and make the surface totally free from any contamination prior to entering into next stage in the process.

3. DERUSTING This stage removes rust, Black Carbon, etc.. from the metal and at the same time make the surface little reactive for the next stage in the process.Chemical base: Phosphoric

4. WATER RINSE To remove the chemical from the earlier stage and make the surface totally free from any contamination prior to entering into next stage in the process.

5. PHOSPHATING It gives a deposition of insoluble metal phosphate by chemical reaction. Since the deposited coating forms by a chemical reaction it gives good adhesion and good corrosion resistance to the powder coating film. Chemical base: Zinc

6. WATER RINSE To remove the chemical from the earlier stage and make the surface totally free from any contamination prior to entering into next stage in the process.

7. PASSIVATION This stage helps in sealing the cavities in the phosphate coating and thus increases the corrosion resistance of the coating.

PRE-TREATMENT PROCESS FOR NON FERROUS (AL, ZINC ALLOYS)

COATING AND BAKING

Our well-trained, skilled and experienced team coats the component with the Electrostatic spray gun, to produce the desired thickness of powder coating on the component.
