| Product Profile | Thermosetting polyester powder coating is made of high quality polyester, curing agent, additives and pigments. Varieties of high light, half light, sub light, low light, no light, metal effect, art, wrinkles, wood grain, transparent and other color products. | |
| Characteristic | The coating has excellent weather resistance and chemical resistance, tight and tough film, high mechanical strength. | |
| Applicability | It is specially used for the coating of high-grade building aluminum profile and highway guardrail. | |
| 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 recommended to use yellow chromate or green chromate to pretreat the aluminum before coating according to ISO / dn50939 standard. It is recommended to use deionized water for the last water cleaning, and dry it in a drying oven not higher than 90 ℃ to ensure the best adhesion and achieve the best durability. | |
