■Corrosion of Metals Corrosion refers to a state in which the appearance or function of an object is impaired due to chemical or biological actions. Iron is generally cited as a metal material that is prone to corrosion. These metals can develop rust and corrosion as a result of factors that cause corrosion, such as oxygen, sulfur, nitrogen, and water vapor in the atmosphere, along with the inherent properties of the metal, impurities, and electrochemical reactions. ■Three Elements of Corrosion - The flow of electricity - The presence of water - The presence of oxidants By preventing any one of these elements through coating, metal corrosion can be prevented. ■Prevention of Metal Corrosion by Teflon Coating 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 superior chemical resistance but also due to its properties such as heat resistance, cold resistance, weather resistance, non-stick properties, purity, low friction, and processability. It can be said that advancements in both the development of Teflon resin varieties and processing technologies have allowed for the selection of materials and shapes suitable for various applications. *For more details on Teflon coating, please refer to the catalog or contact us.*

■Types of Lubrication Lubrication can be broadly divided into liquid lubrication using liquids and solid lubrication using solids. A representative example of liquid lubrication is lubrication with oil. On the other hand, lubrication with fluororesin falls under the category of solid lubrication. ■Characteristics of Solid Lubrication Solid lubrication is used in cases where liquids cannot be used or when liquids evaporate or detach in a vacuum. For example, when sliding products, solid lubrication is useful in cases where liquid lubricants would dirty the products. ■Lubricity and Low Friction of Fluororesin (PTFE) Fluororesin has a low coefficient of friction and is used as a solid lubricant. Fluororesin PTFE is structured such that fluorine atoms surround carbon atoms without gaps. The free energy of the fluorine atoms on the molecular surface is low, and the molecules have a very small polarity due to their symmetrical structure. The low coefficient of friction of PTFE is believed to be influenced by this type of molecular structure. ■Reasons for the Low Coefficient of Friction of Fluororesin PTFE → For more details, please check the basic information section.

■Concern This was a consultation regarding the transportation line where liquid-filled packs are conveyed by sliding them down a stainless steel chute. The issue was that the stainless steel chute and the liquid packs had poor sliding properties, causing the packs to stop midway and leading to line stoppages. Although a pusher was installed on the transport line to address this, it was inefficient, and improving the sliding properties of the chute remained a challenge. ■Background As a countermeasure, the customer polished the surface of the stainless steel chute with a buff and applied a fluororesin coating. While some improvement was observed, the process using the pusher did not change. Co-deposited fluororesin plating was also attempted, but it did not lead to any significant improvement. ■Adopted Coating "Super TP HL" ■Achieved Effect At Yoshida SKT, we proposed "Super TP HL," which can control surface shape using only fluororesin. After processing one of the actual chutes for testing, it began to slide without the use of a pusher. Currently, it has been adopted across all lines, and it is being used without any issues. *Product information PDF is available for download.

■Concern The customer's adhesive manufacturer was producing various products by stirring and mixing adhesives in stainless steel beakers. During this process, the adhesive would stick to the inner walls of the beaker, preventing proper mixing, so a good non-stick coating was needed. ■Background The customer was already using a fluororesin coating. However, the stirring of the adhesive was conducted at high temperatures above 200°C, and issues arose where the coating would peel off due to contact between the beaker and the stirring blades, leading to contamination of the product with foreign substances. Therefore, they were looking for a coating that offered higher non-stick properties and was less likely to peel off due to scratches. ■Adopted Coating FSR (Fluoro Super Release) HR-3110R ■Adoption Process and Effects Initially, tests were conducted with CHC coat, which has high film hardness even at high temperatures, but some adhesion and film peeling occurred. Therefore, tests were conducted with FSR, which excels in non-stick properties in high-temperature environments. After testing with samples, the beaker was treated with "FSR HR-3110R." As a result, it exhibited non-stick properties that were incomparable to the fluororesin coating, and after about a month of use, there was almost no scratching or peeling of the coating, leading to its adoption.

■Concern We were using equipment to transport ion exchange resin, including hoppers, screws, and casings. Since the ion exchange resin is transported in a wet state, it tends to stick to the equipment due to moisture. Additionally, the resin that sticks gradually loses moisture and changes its properties, so measures to prevent sticking in the transport equipment were necessary. ■Background Initially, fluoropolymer coatings were considered for preventing the sticking of ion exchange resin. Fluoropolymers such as PTFE and PFA are known for their excellent non-stick properties and are used for releasing various materials. In this case, when we tested samples with ion exchange resin, we found that it stuck just like it did to metal and could not be removed. ■Adopted Coating TP Coating TP-431 ■Adoption Process and Effect In experiments, it was found that the ion exchange resin, being in small bead form and wet, stuck to the flat surface of the fluoropolymer due to moisture. To reduce the impact of moisture, we tested the TP coating, which forms fine convex surfaces on the surface. After several tests, TP-431, which showed the least sticking, was adopted. *For more details, please visit the official Yoshida SKT website or contact us.*

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.

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.

■ 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.

Vibrating screens and powder transport machines generate vibrations, which often cause general-purpose silicone to tear the processed ducts or mix into the products. When replacing duct bands, the line must be stopped, and in cases of silicone contamination, it may be necessary to dissolve the product to remove the contaminants, leading to many companies struggling with maintenance and upkeep. Introducing "ST Silicone," a durable silicone rubber that solves these issues. We are currently offering a collection of case studies as a gift. *For more details, please download the catalog or contact us directly.

I want 'release properties' and 'slip properties,' but I don't know which coating is good. Do you have any concerns or requests like these? - 'I'm worried about coating degradation and peeling.' - 'I want to extend the period until reprocessing.' In production environments, a 'damage-free' coating is always required. Bycoat is a coating that pursues a balance of [durability and hardness] and [anti-adhesion and slip effect]. [Examples of Applications] - Conveyance Guide Provides slip properties to prevent clogging of conveyed items. Reduces the risk of coating peeling and foreign matter contamination. - Heat-Seal Type (Sealer) Prevents adhesion of sealing materials that press film with heat and prevents coating peeling. - Molding Type Contributes to improved release properties of resin product molds. Maintains dimensional accuracy, allows for low-temperature processing, and preserves mold quality. We are currently offering a free 'Bycoat(R) Experience Kit.' Please try the difficulty of adhesion and ease of slipping with actual materials. ▼ You can apply for the 'Experience Kit' from the official Yoshida SKT website below.

■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!

■Concern We received a consultation regarding a problem where a blade used to punch out polyurethane rubber shapes causes the device to stop due to fragments of polyurethane rubber sticking to the blade. Upon checking, we found that the device sometimes stops on the first shot, significantly reducing the production efficiency of the product. ■Background In the case of punching blades, both release properties to prevent polyurethane rubber from sticking to the blade and slip properties to cut through the rubber without resistance when the blade is pressed into the rubber are necessary. The customer considered a fluororesin coating that excels in both release and slip properties and contacted us. ■Conditions for Choosing Treatment During the hearing, we understood that maintaining the sharpness of the blade edge is necessary for the punching blade to maintain the product shape, and that this is difficult to achieve with a fluororesin coating. We also learned that the customer has been achieving results with silicone release agents as an improvement measure. ■Adopted Coating 'MRS-014' ▼ We are currently offering a free collection of case studies on blade improvements in cutting processes and a trial set! ▼

In mold forming, to stabilize product quality, it is important to improve release properties and prevent mold contamination. Measures such as PVD coating, DLC coating, and chrome plating are being implemented, but depending on the molding conditions, issues can arise where parts of the product stick, or eye residue becomes a cause of product defects. We would like to introduce coatings that have a proven track record of improving the release properties of molds. 【Selected Coatings (Partial)】 ■ Release properties, high hardness, dimensional stability (durable parts, molds) - Bi-Coat ■ Release properties, eye residue prevention - MRS Coating ■ Resin release at high temperatures - FSR Coating ■ Non-stick and slip properties - Teflon / Fluororesin Coating ■ Release properties, precision (precision parts, precision molds) - Nano Process *For more details, please refer to the PDF document or feel free to contact us.

Here is a case study of a certain automotive parts manufacturer. In the process of injection molding epoxy resin under high temperature and high pressure of 150°C, resin adhesion began after about 2,000 shots, necessitating frequent mold changes. The introduction of "Bicoat NYK-01" improved mold life by approximately twice, achieving a significant enhancement in productivity. 【Issues that can be addressed】 ■ Short lifespan of surface treatment for injection molding molds ■ Decreased productivity due to frequent mold changes ■ Resin adhesion issues in high temperature and high pressure environments 【Expected effects】 ■ Achieving approximately twice the mold (surface treatment) lifespan compared to conventional methods ■ Significant reduction in mold change operations leading to increased productivity ■ Reduction in replacement and material costs ■ Stable production due to excellent non-stick and release properties For more details on the case, please refer to the page "Doubling the Durability of Mold Surface Treatment in Automotive Motor Parts Manufacturing." *Product data PDF is available for download.
