Is it feasible to let the powder dry after curing and leveling?
Powder coating does **not “dry”** like liquid paint because it is not a solvent-based process. Instead, it undergoes a **curing** process where the powder melts, flows, and chemically cross-links to form a durable finish.
### **What Happens After Curing & Leveling?**
1. **Curing Stage (in the oven)**
– The powder is heated to its specified temperature (typically **350–450°F / 177–232°C**).
– It melts, flows, and chemically bonds to the surface.
2. **Cooling Stage (after removal from the oven)**
– Once the coating has **fully cured**, it does not need additional drying time.
– The coated part **hardens as it cools** (typically within **15–30 minutes**).
### **Can You Let Powder “Dry” After Curing?**
– **Not necessary**—once cured, the coating is solid and fully adhered.
– **Natural cooling** is recommended to prevent thermal shock or defects.
– If required, **forced air cooling** can speed up handling but should be controlled to avoid stress in the coating.
