Powder coatings are also called 4E products because of their environmental protection, energy saving, safety, and economy.
| Nom du produit | Type | Description du produit | Standard | Weathering life |
|---|---|---|---|---|
| PCNH | Super Weathering | Made of special super weathering resin, inorganic ceramic pigment and special additives, used for outdoor high-end weathering products | AAMA2603-02 | > 10 ans |
| PCNF | modified fluorocarbon | The fluorocarbon powder, which is a combination of fluorine-modified, stable bond-modified super-weather-resistant resin and inorganic special pigments, has the characteristics of super weather resistance, high hardness, water cleaning resistance, acid, alkali and salt resistance. | AAMA2604-05 | > 15 ans |
| PVDF | fluorocarbone | It is developed with 70% fluorocarbon and special pigment fillers, and has the characteristics of high hardness, easy cleaning, solvent resistance, acid, alkali and salt resistance, anti-aging, high weather resistance, etc., commonly known as the “king of coatings”. | GB/T23443-2009 AAMA2605-05 | > 20 ans |
| FEVE | thermosetting fluorocarbon | 70% fluorine content, belongs to thermosetting fluorocarbon powder coating, and the production process and cost are relatively high. | AAMA2605-05 | > 20 ans |
Aluminum parts need to be chromized or passivated before spraying fluorocarbon powder coatings, so that the product can achieve the best performance after spraying.
The distance between the electrostatic gun and the workpiece is 120-180mm, the voltage is 40-80KV, and the current is 10-20uA. Due to the differences between various electrostatic spray guns, it is recommended that the atomization parameters and powder output be adjusted according to the needs of the site.
Curing temperature: 235±5℃ (actual heating temperature of the workpiece)
Curing time: 15-20min
