| Gravidade específica | 1.4~1.8g/cm’ (depending on the formula and color) |
| tamaño de partícula | Depending on the purpose, the standard type has an average particle size of 35~40 microns, less than 10 microns of powder <10%, more than 100 microns of powder <0.5%. |
| Estabilidade de almacenamento | Polyurethane powder coatings should be stored in a dry, ventilated room below 30°C, and avoid direct sunlight. If stored in an air-conditioned room, the powder must not 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 more than 12 months. If it is exceeded, it must be re-tested. If the result meets the requirements, it can still be used. |
