| Composition | It is made of epoxy resin, polyester resin, pigment, filler and additives through melting, extruding, grinding and processing. | |
Main features | 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. | |
Product series | It can be made into common powder with various glosses and colors, art powder and power coating with metal effect according to customers’ requirements. | |
Technical indexes
| 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. | |
| Hardness | ≥2 H | |
| Bending mm | 2 | |
| 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 | |
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; 2. In case of high requirements, spraying and curing should be made after polishing the omitted part with sand paper and spraying the whole surface. | |
