Factors that negatively affect the quality of painting.

Coating defects carry risks that can occur at various stages of the coating process. Here are the typical causes of issues and the corresponding countermeasures.

"Approaches to Improving Coating Quality" The causes of defects and troubles that occur in the coating process can be classified into five categories: 1. Defects due to the condition of the substrate 2. Defects due to the quality of paint or solvents 3. Defects in coating equipment or facilities 4. Defects in application methods or conditions 5. Defects due to the application environment These issues can be avoided through proactive measures. However, defects caused by the application environment may require capital investment or process changes. Nevertheless, by adjusting processes according to weather conditions and managing delivery schedules, troubles can be avoided. When coating defects occur, the corrosion resistance and appearance of the product are diminished, necessitating corrections through sanding or stripping the coating. This is a labor-intensive and time-consuming task that also incurs costs. Therefore, it is essential to address the causes in advance to improve coating quality.
