| Application | Factors such as plant capability, specifications, and pipe construction or characteristics can affect application conditions. The recommended application temperature range is 190-220ºC. |
| Surface Preparation | Remove all surface contamination before abrasive blasting. Blast clean using steel grit to Sa2.5 near-white metal with a surface profile of 50-100 microns. |
| Storage | 1. The product should be stored in a cool, ventilated, dry room with temperature below 25ºC and humidity below 65%. 2. Keep away from fire and heat and tide. 3.After use, it should be sealed in time to prevent powder from being been polluted and damped. 4. Reduce the number of movement to avoid impact and pressure. 5. The maximum stacking height should not exceed 5 layers. |
