■10under Development Background Fluororesin coatings are sometimes requested for processing in thin films of around 10μm, especially when dimensional stability of the substrate is a priority. However, in the case of standard fluororesin coatings, a thickness of at least 20-50μm is required to maintain good appearance and performance. Even so, when requests for thin film processing arise, we sometimes propose a "modified type" of fluororesin coating that alters the coating structure. However, there were challenges with the modified type not being able to deliver the required functions. Yoshida SKT has worked on developing a solution to these challenges, resulting in the creation of “10under.” ■Features of 10under - Non-stick properties equivalent to standard fluororesin coatings - Capable of processing thin films of around 10μm, reducing dimensional changes - While being a thin film, it suppresses transparency *For more details, please download the materials or contact us.*

■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.*

We would like to introduce an improvement case of an automatic label application device using robots. ■Issues In the label application process using robots, the labels peeled off from the release paper are placed adhesive side down on a platform, from which the robot picks them up and applies them to the products. However, there were frequent troubles where the robot could not smoothly peel the labels from the platform, causing work stoppages. ■Requests Initially, we tried a silicone coating with excellent release properties, but the silicone transferred to the labels, reducing their adhesive strength, which led to the labels peeling off after being applied to the products. Additionally, the conventional Teflon™ coating did not sufficiently prevent the labels from sticking. To solve this, it was necessary to achieve both excellent release properties and silicone-free performance. 【Issues to be resolved】 - Label peeling due to silicone transfer - Cleaning time for label adhesive - Line stoppage troubles due to sticking ■Adopted Coating 'Super TP 250 UNDER' *For more details, please download the PDF or contact us.

■Concerns Lead-acid batteries, widely used in automobiles and commercial power sources. In the production process, after filling a resin box with electrodes and other components, the container and lid are welded to seal them. The heating plates used for welding are made of aluminum and are heated to over 200°C, but due to the occurrence of melted resin and stringing, a fluororesin (PTFE) coating was applied. ■Background In a production line that operates at temperatures above 200°C and produces several thousand shots a day, the coating on the heating plates peels off in less than a week. Reprocessing the coating has caused issues such as the hassle of changing setups and damage to molds, leading to decreased production efficiency. ■Adopted Coating "CHC-1111CR" ■Adoption Background and Effects Therefore, we proposed the newly developed "CHC-1111CR," which has equivalent release properties to fluororesin coatings and high hardness of the coating film during heating, making it resistant to peeling and wear. Testing on the actual line showed no stringing of the resin and no peeling of the coating, allowing for use in tens of thousands of shots and achieving a lifespan approximately three times that of conventional coatings. *For more details, please refer to the PDF document.*

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.

■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.

■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.

We have prepared a series that exhibits excellent non-stick properties, particularly against sticky substances, molten resins, adhesives, and adhesive tapes. ■ Series Composition - Super TP/TP Series (composed entirely of fluororesin) - Super CTT Series (composed of surface treatment + silicone-based materials) - Super Alloy Coating (composed of fluorine type and silicone type) ■ Super TP/TP Series (composed entirely of fluororesin) This series can be used in silicone-free environments. Additionally, since it is made entirely of fluororesin, there is no concern about transfer or contamination from silicone oils. Improved slip properties can also be expected due to reduced contact area. ■ Super CTT Series (convex surface + silicone rubber-based) Due to the use of silicone, this series exhibits excellent non-stick properties and low tackiness. Consideration for transfer to the counterpart material is necessary during use. ■ Super Alloy Coating A convex release coating that balances flexibility and high hardness. Surface treatment of HV600 can also be processed onto resins and sponge rubber. *For more details, please download the PDF or feel free to contact us.

■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.*
