Are you troubled by pinholes that create small holes in the painted surface? Even if they appear minor, they can often lead to quality issues. Many of the causes are due to solvents in the paint evaporating rapidly or gases emanating from the substrate. Particularly, thick applications and deviations in drying conditions can easily trap air bubbles inside. Additionally, the frequency of occurrence can vary significantly depending on the type of material and the state of pretreatment. As a countermeasure, managing film thickness and optimizing the drying process are crucial. So, why do pinholes occur sometimes even under the same conditions? Paint defects cannot be improved with a vague approach. Accurately identifying the cause is the first step in preventing recurrence. Our company has published materials summarizing case studies on improving paint defects, including pinholes. Please take a moment to review them to avoid repeating the same issues.

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. Please take a moment to review them to avoid repeating the same troubles.

When performing powder coating, there are several constraints in the manufacturing of the powder coating materials, which has led to the following drawbacks until now: ● Designated colors cannot be produced unless a demand of at least 150 kg of powder coating is anticipated. (Therefore, small lot painting is not possible.) ● Additionally, the production of designated colors requires a period of more than one month. (Thus, delivery times measured in days are not feasible.) With this situation, it has been difficult to adopt powder coating despite its advantages. We are advancing initiatives as part of our "new approach to powder coating," including: ● Utilizing a stock of over 2,000 colors based on the color card system from powder coating manufacturers. ● Collaborating with paint manufacturers capable of small-scale production of powder coatings, enabling designated color powder coating to be realized within one week, even for small lots. We have established a system that leverages the strengths of powder coating, such as the ability to achieve a thick film (approximately 50μ to 100μ) in one coat, minimal VOC emissions (almost zero during processing), and faster painting speed compared to solvent-based coatings.

Whether it is powder coating, solvent-based baked coating, or air-drying coating, the adhesion performance of the paint film and its corrosion resistance greatly depend on the pre-treatment methods that create a suitable condition for painting. In other words, simply removing oil and dirt does not create an ideal condition for painting. Pre-treatment refers to preparing the surface to be suitable for painting. One of the methods that provides excellent corrosion resistance and adhesion among pre-treatment processes is zinc phosphate coating. We regularly measure the concentration of the treatment solution to ensure stable quality.

When high quality and adhesion are required for the painting of aluminum (die-cast) and zinc die-cast products, we adopt "chromate treatment," which is a pre-treatment for painting aluminum (zinc). By applying "chromate treatment" to aluminum materials and zinc die-cast products, which are considered difficult for paint to adhere to, we can impart "high adhesion" and "high corrosion resistance." These non-ferrous metal materials often encounter adhesion issues during painting. It is necessary to align the required quality and painting specifications during the design phase of the painting process.

By applying zinc plating to the product, it can achieve high rust resistance and corrosion resistance. Furthermore, by applying chromate treatment to the zinc-plated surface, discoloration (whitening) of the zinc-plated surface can be suppressed and colored. This allows for a wide range of responses to the required corrosion resistance and aesthetic qualities when combined with painting.
