How much powder is used per square meter for electrostatic powder spraying?
The amount of **powder coating** used per **square meter** depends on several factors, including **powder type, coating thickness, and transfer efficiency**. However, the general formula to estimate consumption is:
### **Powder Consumption Formula**
\[
\text{Powder Consumption (g/m²)} = \frac{\text{Film Thickness (µm)} \times \text{Density (g/cm³)} \times 10}{\text{Transfer Efficiency (\%)}}
\]
### **Typical Consumption Estimates**
For a **standard coating thickness of 60-80 µm (microns)** and a **powder density of 1.2-1.8 g/cm³**, the consumption is approximately:
✅ **120-200 g/m²** (with 60-80% transfer efficiency)
### **Key Factors Affecting Powder Usage**
1. **Coating Thickness** – Thicker coatings require more powder (e.g., industrial applications may use **100-150 µm**).
2. **Powder Density** – Lighter powders (e.g., polyester) consume less, while **heavier powders (e.g., metallics)** require more.
3. **Transfer Efficiency** – Typical electrostatic spray guns have **60-80% efficiency**; higher losses increase usage.
4. **Surface Type & Shape** – Complex shapes or **recoating** may need more powder due to overspray and coverage challenges.
