[Case Study on Surface Treatment] Non-Stick Coating for Rubber Punching Blades *Materials Available

Prevent line stoppage of cutting tools for urethane rubber products. Improve production efficiency by solving adhesion issues with a thin film coating on the cutting blades.

■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! ▼

For applications that cannot be satisfied with fluorine or silicone! Non-stick coating.

For applications that cannot be satisfied with fluorine or silicone! Non-stick coating.

Experience excellent non-stick properties for applications that cannot be satisfied with Teflon or silicone coatings! Anti-stick coating.

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.

[Pharmaceutical Industry Case] Solving Infusion Pack Transportation Issues with Fluorine Coating

[Pharmaceutical Industry Case] Solving Infusion Pack Transportation Issues with Fluorine Coating

Transport troubles with infusion packs. Solved with superior slip properties over fluororesin coatings! Improving the slip properties of resin containers such as drip packs.

■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.

Prevention of adhesive adhesion on laminated processing paper for transport shoots! *Surface treatment example

Prevention of adhesive adhesion on laminated processing paper for transport shoots! *Surface treatment example

[Surface Treatment Solution Case] Preventing adhesive adhesion on polyethylene laminated paper. We improve transport equipment with our unique convex fluorine coating.

■Concern The paper used for packaging liquids such as milk cartons is laminated with resin such as polyethylene on its surface. The adhesive used for the lamination process was causing issues by oozing out from the processed paper and sticking to the transport chute, leading to foreign substances adhering to the product (processed paper) and resulting in product defects. ■Background The customer we consulted was using an overseas-made device, which had surface treatment on the transport section since its introduction. Upon inspection, it was found that a fluororesin coating had been applied, but adhesive residue that oozed out from the paper was sticking and hardening, worsening the product's slip characteristics, necessitating frequent cleaning. ■Adopted Coating 'Super TP Hemispherical Graphic HL' ■Effects of Adoption The reduction in contact area of the 'Super TP Coating' and the excellent slip properties of the fluororesin successfully prevented the adhesion of adhesive residue. The smooth convex surface allowed for smooth transport without scratching the laminated paper. As a result, the need for regular cleaning has been eliminated, achieving both a reduction in product defects and an increase in production efficiency.

Prevents adhesion even with high-temperature adhesives! Strong against scratches and peeling - non-stick coating.

Prevents adhesion even with high-temperature adhesives! Strong against scratches and peeling - non-stick coating.

In general fluoropolymer coatings, it is difficult to prevent adhesion with high-temperature adhesives. Here are examples of coatings with excellent release properties and resistance to film damage.

■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.

[Case Study] Improvement of Mold Release for Molding Dies! Non-Stick Coating for Aluminum Molds

[Case Study] Improvement of Mold Release for Molding Dies! Non-Stick Coating for Aluminum Molds

What is the coating used to release rubber products that tend to stick from molds? We will introduce case studies of solutions through the surface treatment of molding molds.

■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.*

Examples of preventing adhesion of ion exchange resins! Special fluoropolymer coating.

Examples of preventing adhesion of ion exchange resins! Special fluoropolymer coating.

We will smoothly transport ion exchange resins that are prone to sticking. Here, we present a case study of a solution using convex fluororesin coating to reduce contact area.

■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.*

Fluororesin Coating: "What is a Coating with Excellent Corrosion Resistance?"

Fluororesin Coating: "What is a Coating with Excellent Corrosion Resistance?"

Fluororesin has excellent chemical resistance and is suitable for applications that require corrosion resistance and purity. The coating protects metals and prevents the leaching of metal ions.

◆Features of Fluororesin Coating with Excellent Corrosion Resistance◆ ■Chemical Resistance of Fluororesin Fluororesin is chemically stable, so it is not affected by most acids, alkalis, or other chemical agents, and ions do not dissolve and leak out. ■Pinhole-Free Coating Technology By applying a fluororesin coating without electrical pinholes to substrates with shapes that cannot be lined with sheets or rotationally molded, we protect against highly corrosive liquids and gases such as acids and alkalis, and prevent the leaching of metal ions from the substrate. ■Prevention of Liquid Penetration and Excellent Blister Resistance Compared to standard fluororesin coatings, our MY lining significantly reduces blister formation and offers a lifespan over ten times longer, with a maximum film thickness of up to 2000μm possible due to our unique processing technology (depending on substrate conditions). With this technology, we provide fluororesin coatings with excellent corrosion resistance. *For more details, please refer to the catalog or contact us directly.

Fluororesin Coating: "What is the difference in fluororesin?"

Fluororesin Coating: "What is the difference in fluororesin?"

I will explain the differences between the representative fluororesins "PTFE," "PFA," and "FEP."

Types and Characteristics of Representative Resins for Teflon Coating and Fluororesin Coating ■ Resin Name PTFE (Polytetrafluoroethylene) ■ Characteristics It has the highest continuous use temperature of 260°C, and in addition to heat resistance, it also excels in non-stick properties and low friction characteristics. ■ Alternative Name Tetrafluoroethylene, 4F ■ Resin Name PFA (Perfluoroalkoxyalkane Polymer) ■ Characteristics An improved resin of PTFE, it has the same continuous use temperature of 260°C as PTFE. It has a low thermal melt viscosity, allowing for a continuous coating with fewer pinholes that could not be achieved with PTFE, making it the best-performing fluororesin for corrosion-resistant coatings. Additionally, PFA is superior in non-stick properties compared to PTFE for certain applications, making it suitable for high-temperature release coatings. ■ Resin Name FEP (Perfluoroethylene Propylene Copolymer) ■ Characteristics An improved resin of PTFE, but with lower heat resistance than PTFE. It can achieve a smooth coating with fewer pinholes through sintering. ■ Alternative Name 4F6F, Tetrafluoro-hexafluoropropylene

The lifespan of fluorine coating improved up to four times: Case study on the improvement of resin thermal fusion process.

The lifespan of fluorine coating improved up to four times: Case study on the improvement of resin thermal fusion process.

Solving the issue of fluororesin coating peeling in the polypropylene container welding process! Achieving four times the maximum usage count, resulting in increased productivity and reduced costs.

■Concern For customers manufacturing resin containers made of PP (polypropylene), there was a process of adjusting the size and welding them in the middle for containers that are split vertically into two parts. ■Background To prevent adhesion of PP on the heat welding plates (heater plates) used for welding PP resin, PTFE coating (fluororesin coating) was adopted. The heater temperature is high, reaching up to 250°C, and since it is pressed against the PP resin during use, the PTFE coating would get scratched, leading to delamination at the interface between the heat welding plate and the coating, necessitating immediate replacement. ■Adopted Coating "CHC-1111CR" ■Adoption Background and Effects While PTFE has high heat resistance and is less likely to soften when heated, we proposed "CHC-1111CR," which has even higher film hardness during heating. In actual machine tests, where PTFE could no longer be used after one cycle, it was found that it could now be used for four cycles, leading to its adoption. The adhesion prevention performance for PP remains unchanged compared to PTFE. *For more details, please download the PDF or contact us.*

[Surface Treatment Example] Improved Release Properties of Heat Plates for Tray Sealers!

[Surface Treatment Example] Improved Release Properties of Heat Plates for Tray Sealers!

[Food Industry Case Study] Improved Non-Stick Properties of Welded Plates with Special Fluoropolymer Coating! Measures to Prevent Adhesion of Films that Stick Even with Fluoropolymer Coatings.

We would like to introduce a case of a coating that resolved the sticking issues of melt film that could not be solved with fluororesin coatings. ■ Background of the Consultation A certain customer was handling a tray sealer that covers plastic trays with film. In the process of covering plastic containers with film, the film is melted and thermally bonded to the plastic container. The thermal bonding plate is heated to over 100°C, causing the film surface to melt. To prevent the film from sticking to the heating plate, a fluororesin coating was applied. ■ Background of Coating Selection Fluororesin coatings are often used for their excellent non-stick properties, but depending on the material of the film and the melting temperature, they were causing product defects by sticking to the heating plate. Additionally, the heating plate had small holes for vacuuming the film, which limited the options available. ■ Coating Adopted 'TP Coating' *Please scroll down for more details. *For more information, please refer to the materials or contact us directly.

[Surface Treatment Example] Prevention of Resist Liquid Adhesion with Ultra-Thin Fluorine Coating

[Surface Treatment Example] Prevention of Resist Liquid Adhesion with Ultra-Thin Fluorine Coating

Achieve high water and oil repellency and release properties with an ultra-thin film! Fluorine coating with a thickness of less than 100 nanometers, 'Nano Process TC-10S' *Case studies and materials available.

We will introduce a case where the ultra-thin film fluorine coating "Nano Process TC-10S" achieved liquid drainage of the resist and improved product defects. ■Challenge Points - When applying resist liquid to a film-like substrate, the resist liquid adheres to the suction jig, causing the jig's resist liquid to stick to the next transport substrate. - Adhesion of resist liquid to the substrate causes product defects. - To prevent resist adhesion, the frequency of jig cleaning has increased. - With Teflon coating, the surface irregularities are transferred as patterns onto thin substrates, leading to product defects. ■Solution Points - The thin film fluorine coating with a thickness of less than 1μm does not transfer surface irregularities to the substrate. - The release properties of the resist liquid are good, reducing the risk of liquid adhesion to the substrate. - Reduction in cleaning time for suction jigs. - Decrease in product defects. ■Features of TC-10S - It maintains optical properties with almost no dimensional changes. - It enables processing in fields that require "precision parts" and "high dimensional and surface accuracy," which were difficult to process with previous fluororesin coatings. *For details on the case and surface treatment, please refer to the PDF document or feel free to contact us.
