Technical indexes


Residue on sieve %125 μm0 or based on negotiation
Color and appearance of paint film

The paint film should be smooth but slight orange peel

is allowed and the color should meet

the color difference specified.

Hardness≥2 H
Bending mm2
Adhesive force (1×1 mm) Grade 6×60
Impact resistance kg.cm≥40
Acid resistance (HCI 3%)240 hThe film has no change.
Alkali resistance (NaOH 5%) 168 hSlight change is allowed but it shall be recovered within 2h
Salt spray resistance 400 h≤ Grade 1
Damp-heat resistance 500 h≤ Grade 1
Film thickness μm50~60

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.


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: 180/15 minutes or customized according to customers’ requirements.

Additional coating: different measures should be taken for the specific conditions:

1. If the requirements are not high, paints with the same color can be used for additional coating;
