Composition

It is made of epoxy resin, polyester resin, pigment, filler and anti-yellowing additives through melting, extruding, grinding and processing.

Main features

 The gloss can be adjusted within 5-60% (60°);

Good anti-yellowing performance;

Good physical and mechanical performance and resistance to chemicals and heat.

Application

It is applicable to the coating of household appliances, instruments, meters, light industrial products, office equipment, library equipments and electromechanical equipment with relatively high requirements.

Product series

Powders with different glosses and colors can be made according to customers’ requirements.

Surface 

prepartion

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

 shot blasting or blast cleaning

1. The surface roughness should be 30 ~75 μm if reaching Grade Sa2.5 by shot blasting or blast cleaning.

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
