Transportation packaging
Carton packaging, lined with two layers of polyvinyl chloride plastic bags, net weight of each box is 20kg. Non-hazardous items can be transported in various ways, but should be avoided from direct sunlight, moisture and heat, and contact with chemicals.
Hygiene and safety
Operators should wear dust masks during use to avoid inhaling dust and minimize long-term contact between skin and powder coating. Paint attached to the skin can be washed with soap.
Powder properties
| Characteristics | The product has excellent leveling, strong adhesion and good salt spray resistance. |
| Specific gravity | 1.2~1.8g/cm’ (depending on the formula and color) |
| Particle size | Depending on the purpose, the standard type has an average particle size of 35~40 microns, less than 10 microns powder <10%, and greater than 100 microns powder <0.5%. |
| Storage stability | Powder coatings for aluminum wheels should be stored in a dry and ventilated room below 35°C, and avoid direct sunlight. If stored in an air-conditioned room, the powder must be stored at room temperature or the same (temperature) as the spraying equipment before use to avoid moisture. Under this condition, the powder can be stably stored for 12 months. If it is exceeded, it must be re-tested. If the result meets the requirements, it can still be used. |
