Have you ever experienced issues like 'the paint peeling off shortly after delivery'? Even products that seem fine at first can sometimes have adhesion problems beneath the paint film. Many of these issues stem from insufficient pretreatment, but one often overlooked factor is 'invisible oils and moisture.' Even a small amount of these residues can prevent the paint from performing as intended. Additionally, depending on the material, the surface condition may not be stable, leading to variations in results even with the same process. As a countermeasure, it is important to reconsider degreasing, polishing, and chemical treatment as 'processes that create adhesion.' Furthermore, drying conditions should take into account not only temperature but also time and the thermal properties of the material. Poor painting cannot be improved with a vague approach. Accurately identifying the cause is the first step in preventing recurrence. We have published materials summarizing specific cases of how we have improved issues such as peeling, bubbling, and pinholes.
