To prevent sticking of adhesive materials, fluororesin coatings (Teflon™ coatings) and silicone coatings are commonly used, but the following challenges may arise: [Challenge 1] Even with surface treatments claiming to prevent sticking, there was not much change. [Challenge 2] It started sticking unexpectedly quickly during use. [Challenge 3] Silicone coating transfers and causes defects in the bonding process (fluororesin did not provide sufficient effectiveness, leading to the choice of silicone). Recently, there has been an increase in customers needing solutions for more adhesive materials, such as wanting to release molten resins that do not fully solidify to shorten process time. Yoshida SKT has coatings that can improve such situations. In general fluororesin coatings, adhesive materials can stick due to various factors. In contrast, treatments that create a rough surface to reduce the contact area with adhesive materials are known. Our company has a unique technology to create convex surfaces using fluororesin and other materials, and we are now offering a kit to experience its effectiveness for free! ▼ You can apply from the "Yoshida SKT Official Site" below.

Adhesive tape often sticks to machines and other materials during the manufacturing process due to its nature. To prevent such issues, it is essential to employ coating technologies that exhibit non-adhesive properties, especially against sticky adhesives. By using appropriate coating technologies, the ease of handling materials on the production line can be significantly improved, contributing to the preservation of product quality. Introduction to Coating Technologies ■ Super TP and TP Series Composed entirely of fluororesin, these can be used in silicone-free environments. The use of fluororesin eliminates concerns about the transfer or contamination of silicone oil, and it is expected to improve non-adhesiveness by reducing contact area. ■ Super CTT Series This silicone-based series features excellent non-adhesiveness and slip resistance. Since it uses silicone, consideration must be given to the transfer to the counterpart material. ■ Super Alloy Coating Consisting of both fluorine and silicone types, it achieves a balance of flexibility and high hardness. Surface treatment of HV600 can also be applied to resins and sponge rubber, achieving high durability. *For more details, please download the PDF or feel free to contact us.

PTFE lining is characterized by the use of pre-formed PTFE sheets and pipes, and it is also referred to as PTFE sheet lining. Since PTFE has non-stick properties, it cannot usually be adhered with adhesives. Lining sheets are used that have been processed to allow adhesion on one side during or after molding (adhesive lining). ■ Advantages of PTFE Lining By using molded sheets, it is possible to create thickness, making it suitable for use in more demanding environments. Additionally, it is characterized by excellent gas permeability. ■ Disadvantages of PTFE Lining PTFE lining is difficult with baked coatings, so the usable temperature depends on the heat resistance of the adhesive. Furthermore, its use in negative pressure environments is generally not recommended. Yoshida SKT offers lining sheet sales and lining construction services. *For more details on lining, please check the materials or feel free to contact us.

■Reasons why fluoropolymer (PTFE) excels in heat resistance and cold resistance The molecular structure of PTFE is such that fluorine atoms (F) surround the C-C bonds without any gaps. The breaking of C-C bonds and C-F bonds at high temperatures is one aspect of "PTFE degradation." The C-C bonds are less likely to break because they are protected by the surrounding fluorine atoms (F). The bond strength of C-F bonds within PTFE molecules is significantly greater than that of other atomic bonds. Additionally, the high bond energy of C-F bonds is another reason for its excellent heat and cold resistance. ■Applications utilizing the heat and cold resistance of fluoropolymers In the case of fluoropolymer coatings, for example, baking molds utilize the non-stick properties provided by the coating to prevent baked goods from sticking to the mold. Furthermore, since it also possesses heat resistance, it can be safely used in applications where it is baked in an oven. Additionally, in household irons, the heat plate is coated with fluoropolymer to take advantage of its smoothness and heat-resistant properties.

Corrosion prevention refers to methods used to prevent corrosion. Metal corrosion is a state in which the appearance and function of an object are compromised due to chemical and biological actions. Iron is generally cited as a metal material that is prone to corrosion. These metals can undergo rust and corrosion as a result of factors that cause corrosion, such as oxygen, sulfur, nitrogen, and water vapor present in the atmosphere, combined with the inherent properties of the metal, impurities, and electrochemical reactions. ■ The three main elements of corrosion: - The flow of electricity - The presence of water - The presence of oxides To enhance corrosion resistance, it is important to prevent one of these three elements. ■ Corrosion prevention using Teflon fluoropolymer Teflon fluoropolymer is widely used as a corrosion-resistant material due to its exceptional chemical resistance among resins. This is not only because of its excellent chemical resistance but also due to its insulating properties, water repellency, and weather resistance. Additionally, advancements in processing technology have made it possible to select materials and shapes suited to specific applications. *For details on coatings and linings that enhance corrosion resistance, please download the materials for confirmation.

■ What are the electrical properties of plastic materials? The electrical properties of plastics, including fluororesins, include "insulating properties," "dielectric properties," and "electrical resistance." Plastic materials generally exhibit the characteristic of not conducting electricity and retaining it. ■ What are the electrical properties of fluororesin (PTFE)? The electrical properties of plastics fundamentally derive from the polymer structure that composes them. Fluororesin (PTFE) is classified as a "non-polar polymer" due to the dense and symmetrical arrangement of atoms within its molecules, resulting in extremely low charge polarization, and exhibits the following electrical properties. ■ Insulating properties of fluororesin The volume resistivity and surface resistivity of fluororesin (PTFE) are very low, making it a material that is difficult to conduct electricity. The dielectric strength of fluororesin (PTFE, 3.2mm thick) is 19KV/mm. Among heat-resistant plastics known as super engineering plastics, it is equivalent to PEEK's 19KV/mm and superior to PPS's 15KV/mm. *For more details, please visit the official website via the link below or feel free to contact us.

Are there any issues with adhesive sticking to the "cutting blades" of production equipment, impairing cutting performance or contaminating products? If cutting tools are used on sticky items or items with adhesive, without implementing "anti-adhesion measures," it can negatively impact profitability. 【Specific Negative Impacts】 ■ Obstruction of Automation Automation of processes requires that human intervention is not needed and that continuity is maintained. If adhesive materials are adhering to the blades, it becomes difficult to automate that line. ■ Increased Cleaning Frequency If frequent cleaning of the blades is necessary, production may not be completed within the expected time, leading to decreased production efficiency. Additionally, increased working hours due to cleaning can raise costs and raise concerns about worker safety. ■ Adhesion to Products and Product Contamination If adhesive or materials stuck to the blades adhere to the next product being cut, it can result in defective products or necessitate repairs in subsequent processes. Furthermore, if the cutting blades lose their sharpness, it can lead to irregular cut shapes and become problematic. Yoshida SKT offers coatings that can resolve such issues. ▽ For a collection of case studies on cutting process improvements and to request a trial set, click here ▽

The 10under thin film fluoropolymer coating possesses non-stick properties equivalent to standard fluoropolymer coatings while being processable at a thickness of approximately 10μm. As a result, the dimensional changes due to film thickness are reduced compared to the standard type. Additionally, despite being a thin film, it minimizes transparency and prevents aesthetic defects. When compared to other fluoropolymer coating products, it is generally considered that a thickness of at least 20-50μm is required to maintain good appearance and performance. Therefore, when requesting processing with a thin film like 10under, it was common to propose a "modified type" fluoropolymer coating; however, there are challenges where the modified type may not exhibit the necessary functions. 10under addresses such challenges and is capable of demonstrating high performance while being a thin film.

【Revealing Some Secrets of Our Successful Increased Production!】 ◆Concerns and Requests◆ In the molding process of a certain automotive part, there was a request to shorten the molding time to accommodate increased production. When attempting to demold the resin from the mold in a shorter time than usual, a problem occurred where the resin had not sufficiently hardened, causing the ejector pins to get stuck. However, this mold required strict dimensional control, with no allowance for even slight dimensional changes such as thermal distortion. The conventional Teflon coating had a high processing temperature of 400°C and did not provide sufficient dimensional accuracy, making it an unsuitable option. The surface treatment that solved this issue was 'Bicoat®'. ◆Background and Effects of Adoption◆ Among Bicoat®, "NYK-52-T" has a low processing temperature of around 200°C and excellent release properties, allowing for smooth demolding even with soft resin without sticking. It also offers good dimensional accuracy, with a coating tolerance of plus or minus 5μm. A major feature is that it can be applied to precision molds with strict dimensional requirements without worry!

■What is blasting? Blasting is a surface treatment method that involves spraying blast materials (various abrasive particles) onto the surface of a product using compressed air or similar means to remove rust and dirt from the substrate surface. The particles that collide with the surface act as "impact" or "cutting." Although the energy of a single blast particle is minimal, the continuous bombardment of countless particles results in a significant effect on the surface. ■Blasting as a pre-treatment In addition to cleaning the surface, blasting increases the surface area through roughening, which generates an anchor effect that greatly enhances adhesion during coating processes. Therefore, it is extremely effective not only for fluoropolymer coatings but also as a pre-treatment for processes such as thermal spraying and plating. Additionally, blasting can improve the wettability of liquids. To fully realize the performance of fluoropolymer coatings, pre-treatment is a crucial process. At Yoshida SKT, we select blast materials and treatment methods suitable for coatings and substrates to process fluoropolymer coatings. *For more details, please check the link below or feel free to contact us.

■Concern When molding rubber of different materials in layers, the products molded in the mold enter the vulcanization process while still in the shape of the mold. The products were made of materials that easily adhered to the mold, resulting in a phenomenon where they stuck to the mold and could not be removed after vulcanization. ■Background During demolding, strong forces are applied, so using standard fluororesin coatings posed a risk of peeling due to insufficient film strength. We recommended a Bi-Coat that excels in release properties and wear resistance, but the mold in question was made of soft aluminum and required surface treatment compatible with sulfur vulcanization, necessitating the selection of a Bi-Coat treatment that could adapt to both conditions. ■Coating Adopted Super Bi-Coat NYY-11-F05 ■Adoption Process and Effects We tested a Bi-Coat suitable for aluminum substrates and usable for sulfur vulcanization. Initially, demolding was good, but rubber adhesion began to occur within a short period. Therefore, we proposed and tested the "Super Bi-Coat NYY-11-F05," which excelled in release properties, achieving both initial demolding and sustained release properties. This led to its adoption. *Product data PDF is available for download.*

This is a case of surface treatment for equipment that transports eye drop bottles arranged in a line, which are dispensed from a prescription. ■Problems to Solve Eye drop bottles were being transported in a manner where they were pushed out one after another over the transport chute. However, on the flat metal surface of the chute, the bottles tended to stick and were difficult to slide, leading to blockages and tipping during transport. ■Goals to Achieve Due to the need for minimal human traffic in the sterile room, it was necessary to use the equipment for at least six months without maintenance, and a surface treatment that improves sliding was requested. ■Background for Coating Selection While fluororesin coatings, which have excellent sliding properties, initially performed well, the surface would become polished due to friction with the bottles. Once worn down to a flat and smooth state, the sliding ability decreased, leading to issues. Additionally, a method was considered where the substrate would be pre-treated to form a rough surface before coating, thereby reducing the contact area. However, since different metals such as aluminum and stainless steel were used for the chute substrate, variations in hardness led to significant changes in surface roughness, and difficulties in processing arose depending on the material. ■Adopted Coating 'TP Coating' ▼ Click here for details on the coating!

We would like to introduce a case where we achieved prevention of adhesive residue on cutting blades when disposing of adhesive-laden packages. ■ Background of Surface Treatment Consideration In the device that removes products from the package, a mechanism was needed to automatically cut and dispose of adhesive-laden packages into smaller pieces. ■ What We Wanted to Achieve The device operates unmanned, with human intervention only required when the finely cut packages fill the dust box. Therefore, it was essential to prevent the adhesive from sticking to the cutting blades, allowing for maintenance-free operation. ■ Conditions for Selecting Treatment Initially, a fluororesin coating, effective in preventing adhesive residue, was selected and tested. However, the thickness of the fluororesin coating, approximately 30μm, caused a decrease in the sharpness of the blades. As a solution, we polished the coating only on the cutting edge and conducted retesting, but this resulted in the cutting edge being uncoated, leading to adhesive sticking. Continuous cutting of packages became impossible. ■ Adopted Coating 'MRS Coating' ▼ We are currently offering a free collection of improvement case studies and a coating trial set! ▼

Reducing defects requires cleaning the tools, which is labor-intensive. ■Request For materials like raw rubber that are soft and highly adhesive, standard Teflon coatings are smooth and slippery, causing them to stick like a suction cup. Additionally, since cutting raw rubber is performed at temperatures around 200°C, a coating that can withstand that environment was necessary. 【Issues to be resolved】 - Product defects due to burrs - Adhesion of raw rubber - Heat resistance - Cleaning costs and labor expenses ■Adopted Coating 'TP Coating TP-411' *For detailed solutions, please download the PDF or contact us.

To prevent adhesion of sticky substances, fluoropolymer coatings (Teflon™ coatings) and silicone coatings are commonly used, but the following challenges may arise: [Challenge 1] Even with surface treatments claiming to prevent sticking, there was not much change. [Challenge 2] It started sticking unexpectedly quickly during use. [Challenge 3] Silicone coating transfers and causes defects in the bonding process (fluoropolymer did not provide sufficient effectiveness, leading to the choice of silicone). Recently, there has been an increase in customers needing solutions for more adhesive materials, such as wanting to release molten resins that do not fully solidify to shorten processing time. "Yoshida SKT has coatings that can improve such situations." With general fluoropolymer coatings, sticky substances can adhere due to various factors. In response, treatments that create a rough surface to reduce the contact area with sticky substances are known. Our company has a unique technology to create convex surfaces using fluoropolymer and is now offering a kit to experience its effects for free! ▼ You can apply from the official Yoshida SKT website below.

Releaseability of a mold refers to the property that allows a product to be smoothly released from the mold. Poor releaseability can lead to issues such as prolonged release time or damage to the product. One effective method to improve releaseability is coating. Coating enhances non-stick properties and improves releaseability by forming a film on the surface of the mold. Depending on the type of coating, the characteristics such as the types of materials with excellent releaseability, durability, and wear resistance vary. Additionally, the appropriate coating differs based on the material and shape of the mold, as well as the type of resin being molded. "Bycoat" is a system that achieves the ideal function of "release + wear resistance" by combining "inorganic surface treatment technology" and "organic surface treatment technology." It withstands harsh usage areas such as injection molds, providing reliable lubrication and releaseability. Furthermore, due to its excellent dimensional accuracy, it is suitable for areas requiring micron-level precision. By processing with Bycoat, releaseability can be improved, reducing product defects and enhancing productivity. *Product materials and case studies are available for PDF download.*
