| Thermosetting polyester powder coating | ||
| Product Profile | CP-03 Thermosetting polyester powder coating is made by using high quality polyester and TGIC. It has various products such as high light, half light, metal effect, art, wrinkles and so on. | |
| Characteristic | The coating has excellent weather resistance and chemical resistance, high mechanical strength and tenacity of coating. | |
| Applicability | Surface coatings for electrical equipment, heating and ventilation equipment, iron wheels, automobile spare parts, agricultural machinery, engineering machinery, office equipment, air conditioners, external decoration materials, mobile houses and other exposed facilities. | |
| Theoretical coverage | 10-12㎡/kg，（Film thickness 60 ų ṃ, with the state of the workpiece, coating method, coating conditions, all the differences） | |
| Dry storage stability | 12 months (less than 30 ℃) | |
| Pretreatment | In order to achieve the ideal adhesion, it is suggested that the substrate should be properly pretreated before coating, and different pretreatments should be adopted for different substrates | |
| 1. Zinc phosphating (improving corrosion resistance and adhesion) | ||
| 2. Iron phosphating (improve corrosion resistance and adhesion) | ||
| 3. Chromizing treatment (improve the adhesion between coating and aluminum substrate) | ||
| Curing process | 1. Low temperature curing 160 ℃ @ 25min (MT) | |
| 2. Conventional curing 180 ℃ @ 15min (MT) | ||
| 3. Rapid curing 200 ℃ @ 10min (MT) | ||
| Construction method | Electrostatic and friction gun spraying, manual and automatic. Metal flash powder can only be applied with electrostatic coating, and arts and crafts powder is recommended to use automatic gun spraying to ensure uniform color and appearance effect. | |
