Powder Coating
 

Powder Coating is a type of coating that is electrostatically applied in a solid state, dry-powder form. Unlike conventional liquid paint, Powder Coating is a solvent free coating process. The coating is applied and cured under heat to allow thin film formation.

Powder coating possess superior chemical and mechanical properties. Here listed some of the features of Powder Coating:

Environmental friendly – solvent free coating process, zero or near zero VOC emission.
Recycling of overspray powder
Thicker dry film thickness (60um – 80um)
Comprehensive color selection – from solid pastel to exotic colors and even metallic colors
Excellent chemical resistance to solvents and detergents.
Excellent impact and abrasion resistance
Different surface texture are available – plain or satin finish

For our Powder Coating products, we can offer 10 – 20 years warranty for outdoor application, according to AAMA 2603, AAMA 2604 or AAMA 2605 specification, depending on different powder resin and color pigment used.



Powder Coating Work Flow  

1. 12 Stages Chemical Pretreatment
  Step 1 - Alkaline degreasing
Step 2 - Tap water rinsing
Step 3 - Tap water rinsing
Step 4 - Etching & Desmutting
Step 5 - Tap water rinsing
Step 6 - Tap water rinsing
Step 7 - Chromate conversion coating
Step 8 - Deionized water rinsing
Step 9 - Deionized water rinsing
Step 10 - Deionized water rinsing
Step 11 - Drying
Step 12 - Quality inspection for chemical pretreatment
2. Dusts on coating surface are removed by air ionizing blowers.
3. Electrostatic spray applied powder coating with dry film thickness 60-80 microns.
4. Coated parts are thermal cured with metal surface temperature 180 - 200 for
10-15 minutes.
5. Quality inspection for coating layer.
