It is made of epoxy resin, polyester resin, pigment, filler and
additives through melting,
extruding, grinding and processing.
Good leveling property and high gloss;
Excellent physical and mechanical performance and resistance to
chemicals and heat;
Good marginal coverage.
|Application||It is applicable to the coating of radiator surface.|
It can be made into common powder with various glosses and colors,
and power coating with metal effect according to customers’
|Residue on sieve %125 μm||0 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.
|Adhesive force (1×1 mm) Grade 6×6||0|
|Impact resistance kg.cm||≥40|
|Acid resistance (HCI 3%)240 h||The film has no change.|
|Alkali resistance (NaOH 5%) 168 h||Slight 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 μm||50~60|
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
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
1. If the requirements are not high, paints with the same color can
be used for additional coating;
2. In case of high requirements, spraying and curing should be made
the omitted part with sand paper and spraying the whole surface.
