Insufficient cleaning is the cause of all painting defects and the truth behind recontamination.
Post-cleaning environmental management determines the quality of the coating.
**Problem** Insufficient cleaning causes residual oil and contaminants on the surface, leading to poor adhesion. **Causes and Issues** - Recontamination occurs due to leaving the surface after degreasing. - Dust and oil from the environment adhere to the surface. - Insufficient cleaning does not provide a fundamental solution. - If drying is inadequate, moisture remains. - Secondary contamination occurs over time. **Management Standards and Guidelines** It is recommended to paint immediately after cleaning. Minimizing idle time is crucial to prevent recontamination. Environmental management is also a prerequisite. **Improvement Examples and Effects** By strictly managing the cleaning process, defects caused by recontamination can be reduced. Adhesion significantly improves, and the quality of the paint film stabilizes.
