Causes and Solutions for Poor Paint Adhesion
创建于2024.07.02
Poor paint adhesion can be caused by inadequate pretreatment and insufficient curing.
Inadequate Pretreatment:
- Problem: Poor pretreatment can result in the coating not adhering well to the workpiece.
- Solution: Ensure regular titration of pretreatment baths and use water-soluble, silicone-free degreasers.
Insufficient Curing:
- Problem: Insufficient curing can lead to weak, easily peeled coatings.
- Solution: Perform thermographic checks to ensure the workpiece reaches the recommended temperature for the specified time.
By ensuring thorough pretreatment and proper curing, the adhesion of powder coatings can be significantly improved.
