How to do Powder Coating ?

1. Degrease

   Oil or Grease is removed by diping CRCA Steel fabrication into Acidic /Alkaline solution at Ambient temperature for 30 minutes.
   Immersion Solution : Acidic/Alkaline Solution.
   Temperature : Ambient/Room Temperature.
   Duration : 30 minutes.

2. Rinse – I

   CRCA Steel Fabrication is Rinsed, so that no Oil/Grease/Acidic solution is transfected to next stage.
   Immersion Solution : Water
   Temperature : Ambient/Room Temperature.
   Duration : 10 minutes.

3. Chemical Cleaning  / Derusting

   CRCA Steel Fabrication is dipped into Hydrocloric Acid, which removes Rust and Mil Scales on the Steel Fabrication. Hydrocloric Acid is kept at Ambient temperature.  
   Immersion Solution : Hydrocloric Acid
   Temperature : Ambient/Room Temperature.
   Duration : 30 minutes.

4. Rinse – II

   CRCA Steel Fabrication is Rinsed, so that no Rust/Hydrocloric Acid is transfected to next stage.
   Immersion Solution : Water
   Temperature : Ambient/Room Temperature.
   Duration : 10 minutes.

5. Surface Activation

   CRCA Steel Fabrication is dipped into Activation chemicals.
   Immersion Solution : Activation Chemical Solution.
   Temperature : Ambient/Room Temperature.
   Duration : 5 minutes.

6. Phosphating

   CRCA Steel Fabrication is dipped into solution of Zinc Phosphate at Ambient Temperature. 
   Immersion Solution : Zinc Phosphate.
   Temperature : Ambient/Room Temperature.
   Duration : 30 minutes.

7. Rinse – III

   CRCA Steel Fabrication is Rinsed.
   Immersion Solution : Water
   Temperature : Ambient/Room Temperature.
   Duration : 10 minutes.

8. Passivation

   CRCA Steel Fabrication is dipped into Decxylite Solution at Ambient Temperature to seal the surface for obtaining maximum corrosion resistance.
   Immersion Solution : Decxylite Solution
   Temperature : Ambient/Room Temperature.
   Duration : 5 minutes.

9. Oven Drying

   CRCA Steel Fabrication is Dryed by Hot Air at 150 *C.
   Environment : Hot Air
   Temperature : 150 *C Temperature.
   Duration : 10 minutes.

10. Powder Coating

    CRCA Steel Fabrication is powder coated by Spraying the Epoxy powder of desired color.
    Environment : Spray of Epoxy Powder
    Temperature : 150 *C Temperature.
    Duration : 15 minutes.

11. Curing / Baking

    CRCA Steel Fabrication is Baked in Electric Oven at 150 *C for 15 minutes.
    Environment : Oven
    Temperature : 150 *C Temperature.
    Duration : 15 minutes.
