Troubleshooting – Powder Coating finish-cured film physical properties
PROBLEM , Cause and Remedy
| PROBLEM | CAUSE | REMEDY |
|---|---|---|
| Poor impact resistance/poor flexibility | Under cured | Increase oven temperature (or): Increase dwell time in oven |
| Poor cleaning or pretreatment | Check pretreatment equipment and chemicals | |
| Film thickness too high | Reduce film thickness by adjusting application equipment | |
| Change in substrate thickness or type | Check substrate with supplier | |
| Powder resin type or formula | Check with powder manufacturer | |
| Poor adhesion | Poor cleaning or pretreatment | Check pretreatment equipment and chemicals |
| Change in substrate | Check substrate with supplier | |
| Under cured | Increase oven temperature (or): Increase dwell time in oven |
|
| Powder resin type or formula | Check with powder manufacturer | |
| Poor corrosion resistance | Poor cleaning or pretreatment | Check pretreatment equipment and chemicals |
| Under cured | Increase oven temperature (or): Increase dwell time in oven. |
|
| Poor chemical resistance | Under cured | Increase oven temperature (or): Increase dwell time in oven. |
| Powder resin type or formula | Check with powder manufacturer | |
