We will introduce a case study of trouble resolution on the transport line for electronic components sealed with resin. ■Issue The electronic components sealed with resin are suctioned by a jig and transported and placed on the substrate. However, there were instances where the slightly adhesive sealing resin would stick to the jig, negatively affecting the yield. ■Request Since the suction jig performs suction, transport, and placement operations tens of thousands of times per hour, high wear resistance was required. Additionally, an image recognition camera is used to confirm the position of the components on this line, so it was necessary to use a color that minimizes reflection to prevent whiteout in the images. ■Adopted Surface Treatment - Bycoat® NYK-01BK ■Background and Effects of Adoption 'Bycoat' was considered for preventing the sticking of the sealing resin and for its wear resistance. After evaluation on actual equipment, it was found to have good wear resistance as well as excellent release properties for the resin. 【Resolved Issues】 - Reduced sticking issues with the resin - Decreased cleaning costs - Improved productivity *For more details, please download the PDF or contact us.

Mold release residue refers to foreign substances that adhere to the surface of molded products when forming thermoplastic materials such as resins and rubber. To prevent this residue, it is necessary to avoid material retention in the mold. When appropriate material selection and molding conditions cannot resolve the issue, adopting a surface treatment with excellent release properties is effective. Here are examples of improvements in mold release residue through surface treatment. ■ Concern We received an inquiry from a customer who was prototyping a new elastomer extrusion product. They wanted to resolve issues related to product stability due to adhesion in the extrusion mold. ■ Background for Coating Adoption Initially, the adhesion was so severe that it was impossible to form the product, but after adopting our surface treatment, we were able to prevent adhesion to a level that allowed for production. However, during continued mass production, it became apparent that defects due to residue adhesion occurred after about a month of use. ■ Selected Surface Treatment 'MRS Coating MRS-102' *For details on 'MRS-102', please download the PDF or contact us. The effects of the surface treatment are listed below.

We will introduce a case of surface treatment that improved rubber sticking troubles in tire manufacturing equipment. ■Problem During the transportation process of tire manufacturing, when removing the donut-shaped rubber from the transport mold, the rubber stuck and could not be removed smoothly. This frequently caused line stoppage troubles, resulting in decreased production efficiency. As a solution, we tried a standard Teflon coating, but because the coating surface was smooth and slippery, the still-soft rubber stuck like a suction cup, proving ineffective. ■Request Silicone coatings and silicone release agents, which excel in release force, cannot be used due to the issue of silicone transfer interfering with the subsequent rubber bonding process. Therefore, a silicone-free release coating was required. ■Challenges to be solved - Release troubles - Line stoppage troubles - Decreased productivity ■Coating that resolved the issues Super TP Hemisphere Graphic HS How the issues were resolved can be found in detail by downloading the PDF or by contacting us.

■What is the "Water Repellency" of Fluororesin? "Water/Oil Repellency" refers to the property of a material's surface to repel water and oil. A well-known example that illustrates this property is the lotus leaf. The lotus leaf utilizes this water repellency to keep itself clean and less prone to wetting, allowing for smooth photosynthesis. Teflon fluororesin also possesses this "water/oil repellency." For instance, even if a liquid tends to spread on a material, applying a Teflon fluororesin coating to the surface can impart water/oil repellency, causing the liquid to bead up and reducing its tendency to spread. You can find detailed information in the PDF document below. ---------------------------------------- 1. What is water/oil repellency? 2. Reasons why Teflon fluororesin excels in water/oil repellency ~Surface Free Energy~ 2-1. What is surface free energy? 2-2. The relationship between water repellency and surface free energy 3.

The manufacturing process of weather strips involved transporting extruded rubber on rolls while heating and drying it in a furnace. Due to changes in the rubber material formulation for environmental measures and durability, it became necessary to process the rubber at higher temperatures than before, resulting in the rubber becoming sticky immediately after entering the furnace. When a common fluororesin coating was applied to the transport rolls, it was confirmed that the rubber stuck to them like a suction cup. By adopting our "Super TP Coating," we significantly reduced the sticking of the rubber and achieved a relatively soft contact surface. [Case Study] ■ Purpose of surface treatment: Quality improvement, operational stability, reduction of work loss, compliance with safety and environmental requirements ■ Required functions: Non-stick, release properties, long lifespan ■ Treatment adopted: Super TP Coating *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case of surface treatment that improved the liquid drainage of measuring cups. ■Concern In the case of a standard measuring cup, liquid was drained by either tilting it at a steep angle or shaking it by hand. Particularly with heavy cream, the drainage was poor, requiring multiple shakes or the use of a spoon. Initially, we considered Teflon coating, but it did not perform well with heavy cream. ■Request When we received the consultation, the client was using a thin-film fluorine coating from another company, but there were many inconsistencies in the processing, and the liquid drainage was unstable, sometimes good and sometimes bad. ■Coating that solved the issue MRS-014 ■Background of adoption At Yoshida SKT, we produced a prototype of the MRS coating, which is a food-safe type with a thin film. By combining it with a special base treatment, we achieved good liquid drainage even with heavy cream. The ability to pour at a right angle also improved workability. The MRS coating is about 1μm thick, so there is almost no risk of volume error or foreign matter contamination. Additionally, at the World Bartender Championship, the ability to pour at a right angle was well received for making the actions look elegant. *For product details, please refer to the PDF.

When using a household frying pan for a long time, the fluoropolymer coating may peel off or wear down, leading to sticking issues. The fluoropolymer coating can be removed and reprocessed. However, household frying pans are not designed with reprocessing in mind, which brings both advantages and disadvantages. ■ Advantages - The coating of a beloved cooking tool is renewed, restoring the non-stick properties and ease of maintenance similar to that of a new product. - There is no need to buy new equipment, and disposing of the old frying pan is not a problem. ■ Disadvantages - Reprocessing requires high-temperature heat treatment (over 400°C), necessitating the removal of handles made of resin or plastic. (If they cannot be removed, reprocessing is generally not possible.) - A frying pan that has been used for a long time may have corrosion on the metal parts, and even if the coating is reprocessed, it may not return to a like-new condition. - Especially in cases where the metal thickness is thin, reprocessing may cause distortion and deformation. - There may be adverse effects on the exterior, resulting in a poor appearance. As such, reprocessing has many disadvantages as well as advantages, so caution is necessary when it comes to household cooking utensils.

Why does fluoropolymer coating repel water? We will introduce the relationship between surface energy, non-stick properties, and water repellency. ■ The relationship between water droplets and surface energy The reason the surface of fluoropolymer coating repels water is that the surface tension of water acts strongly. The same principle applies to sticky substances. In other words, "difficult to wet = difficult to stick." The action of liquid surface tension is strongly related to the surface free energy of solids. Surface free energy is the force that tries to attract the molecules of the contacting counterpart. Water is a substance with higher surface tension compared to oil. When in contact with a solid that has the same surface free energy, oil tends to spread and wet more easily, while water tends to bead up and is harder to wet. The smaller the surface free energy of the solid compared to the liquid it contacts, and the greater the difference, the more difficult it becomes for the liquid to wet (stick). The surface of fluoropolymer coating has very low surface free energy, which allows it to repel not only water but also oil, making it an effective surface treatment for release purposes due to its low tendency to stick.

**Basics and Types of Release Coatings** Release coating is a surface treatment technology that involves applying a special coating to the surface of molds and forming machines to prevent molded products from sticking to the molds, allowing for smooth removal. By improving release properties, it enables shorter production cycles and stabilizes product quality. In manufacturing sites troubled by release issues with molds, outsourcing coating to contract processing manufacturers with specialized technology allows for high-quality surface treatment that may be difficult to achieve in-house. **Main Types of Release Coating Technologies** There are various types of release coatings, and the optimal method is chosen according to the application. - **Silicone-based Coatings:** Particularly excellent for molten resins and adhesive release. - **Fluoropolymer (Teflon) Coatings:** Using materials like PTFE, PFA, and FEP, they exhibit high release effectiveness. - **Ceramic Coatings:** Ideal for applications requiring high durability due to their excellent wear resistance. It is important to select these coating technologies based on the substrate and usage environment, and release coating manufacturers provide optimal processing. *For more details, please refer to the PDF document or feel free to contact us.*

Here, we introduce part of the quality inspection for Teflon coating. ■ Product Inspection We verify whether the product meets the meeting notes and order specifications based on the meeting minutes, drawings, and individual items. ■ Coating Appearance Inspection The processed coating is visually observed under diffuse daylight (equivalent). In principle, any detection of blisters, cracks, peeling (including interlayer peeling), substrate exposure, or transparency will result in a failure. ■ Film Thickness Measurement Inspection Film thickness refers to the thickness of the processed coating measured using a thickness gauge adjusted based on the substrate board and a standard board placed on top. ■ Pin Hole Inspection Pinholes are a general term for tiny defects that can potentially be detected electrically. However, it typically refers to one type of tiny defect, specifically holes that resemble those made by a needle, found in the remnants of bubbles. *Inspection items may vary depending on the coating specifications.
