Surface prepartion

The corresponding treatment method should be used based on the substrates, such as phosphating, chromizing, shot blasting or sand blasting

1. The surface roughness should be 30 ~70 μm if reaching Grade Sa2.5 by shot blasting or sand blasting.

2. Phosphating: degreasing- derusting- neutralizing- surface control- phosphating- passivating

Appearance of phosphating film: The phosphating film should be crystallized densely, continuously and evenly.

3. Chromizing: degreasing- rinsing- immersion cleaning- deoxidating- rinsing- chromizing

Method of Application

It is applicable to high voltage electrostatic spraying

Spraying voltage: 50-90 kV; air pressure for spraying: 0.1-0.2 Mpa; distance between the gun and workpiece: 200-300 mm

Curing condition: 180-200℃/10-15 minutes or customized according to customers’ requirements.

Additional coating: spraying and curing should be made after polishing the omitted part with sand paper and spraying the whole surface.
