Why is it a problem if there are pinholes in the Teflon coating film in the first place? In a typical fluororesin coating (thickness: 20-50 μm), there are countless holes (pinholes) that are invisible to the eye and reach the substrate. For applications that require non-stick or slippery properties, these pinholes rarely have a negative impact on performance. However, in applications where corrosion resistance is required, chemicals can reach the substrate (metal) through the pinholes, causing corrosion and leading to holes or causing the coating to peel off. To eliminate pinholes, the coating can be thickened by applying multiple layers, ensuring that there are no pinholes that connect the coating surface to the substrate. At Yoshida SKT, we conduct inspections using insulation resistance meters, pinhole testers, and chemical detection methods according to the coating specifications and substrates. These methods are non-destructive tests that do not damage the coating film. *For more details on pinhole inspection, please visit our website via the link or contact us.*

■Is the chemical resistance of fluoropolymer high? Fluoropolymers have high chemical resistance and do not dissolve, swell, or react with most acids, alkalis, and organic solvents. ■Reasons for the high chemical resistance of fluoropolymers A major reason for the excellent chemical resistance of fluoropolymers is their stable molecular structure. Fluoropolymers are high molecular weight polymers with carbon atoms and fluorine atoms bonded in a linear chain structure. The bond energy between carbon and fluorine atoms (C-F) is very strong among chemical bonds, and furthermore, the C-C bond sections between carbon atoms are completely covered by fluorine atoms in a helical manner. Therefore, they remain inert when in contact with chemicals or solvents, and do not degrade or dissolve as a resin, which means they have excellent chemical resistance. ■Uses of fluoropolymers The chemical resistance of fluoropolymers is utilized in the chemical industry, semiconductor industry, and medical and pharmaceutical fields in products such as: - Various gaskets - Seals - Piping and hoses - Storage tanks - Reaction vessels - Heat exchangers *For more details, please download the materials or refer to the link below.

■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 may evaporate or detach in a vacuum. For example, when sliding products, solid lubrication is helpful in situations where liquid lubricants may dirty the products. ■Low Friction and Sliding Properties of Fluororesin (PTFE) Fluororesin has a low coefficient of friction and is utilized for solid lubrication. 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 molecule has a very small polarity in its target 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 → Please check the basic information section for more details.

■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.*

■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 have a coating at Yoshida SKT that can address such concerns." Bicoat® is a coating that pursues a balance of [durability and strength] and [anti-adhesion and slip effect]. It reduces the possibility of troubles caused by "functional decline due to coating scratches and peeling, foreign matter contamination, and defects," which can lead to decreased production efficiency. - Provides slip properties to conveyor chutes, preventing blockages of transported items. Reduces the risk of coating peeling and foreign matter contamination. - Prevents sticking of heat sealer's bonding film and coating peeling. - Contributes to improved release properties of resin molding molds. Maintains dimensional accuracy, allows for low-temperature processing, and preserves mold quality. 'Bicoat®' samples are currently available for free. Please try the anti-adhesion and slip properties with actual materials. ▼ You can apply from the official Yoshida SKT website below.
