| Product Profile | Cp-05 thermosetting polyester powder coating is made of special polyester, special curing agent and additives. This product does not contain TGIC, more in line with environmental requirements. Varieties of high light, half light, matte, metal effect, art, wrinkles and other color products. | |
| Characteristic | The coating has excellent weather resistance and chemical resistance, high mechanical strength, tough film and excellent weather resistance. | |
| Applicability | Surface coating of outdoor exposed facilities such as aluminum profile, electrical equipment, heating and ventilation equipment, iron wheel, automobile spare parts, agricultural machinery, engineering machinery, office equipment, air conditioner, expressway guardrail, external decoration materials, movable house, etc. | |
| 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 | Aluminum: according to the ISO / din50939 standard, the aluminum material is pretreated with yellow chromate or green chromate. It is recommended to use deionized water for the last water cleaning, and dry in the drying furnace at no more than 90 ℃ to ensure the best adhesion and achieve the best durability. Steel plate: chromate or zinc phosphating. It is suggested that the best protection should be given to the former drug suppliers. Galvanized sheet: phosphating with zinc chromate. In order to avoid pinholes in the cured coating caused by tiny bubbles, preheating is recommended. | |
| 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. | |
