■What color is fluoropolymer? The fluoropolymer coating commonly seen on household frying pans is often a dark color, but PTFE, which is frequently used for frying pan coatings, appears milky white under sunlight. ■Colors of fluoropolymer coatings Fluoropolymer coatings come in various colors, including green and gray, in addition to dark colors. This is because the coating materials are colored to enhance aesthetics and allow for differentiation based on purpose. ■Differences by color The differences in color of fluoropolymer coatings are not closely related to the type or characteristics of the resin. For example, green does not necessarily indicate PFA, nor does black indicate PTFE. Since fluoropolymer coatings are functional films, it is essential to choose them appropriately based on their intended use and environment. In such cases, it is important to consult a reliable processing company rather than selecting based solely on color. ■Fluoropolymer coatings for specific applications Fluoropolymer coatings demonstrate various functions depending on the type of resin, film thickness, and processing methods, across different applications and environments. It is crucial to select the appropriate coating based on the intended use, such as for non-stick purposes or corrosion resistance.

Fluororesin is a material that exhibits excellent chemical resistance to almost all chemicals. Hydrochloric acid is a strong acid that can dissolve many metals, but fluororesin does not dissolve in hydrochloric acid. Fluororesin is generally not affected by hydrochloric acid on its own; however, caution is necessary when used as linings or coatings intended to protect metals. Hydrochloric acid can penetrate fluororesin linings or coatings depending on its concentration and temperature. This penetration can lead to blistering, which impairs corrosion resistance. Additionally, thin fluororesin coatings may leave pinholes, allowing hydrochloric acid to infiltrate and directly corrode the substrate. If you want to protect metals from chemical solutions like hydrochloric acid, please consult us when considering measures involving fluororesin.

CFRP is a material that significantly contributes to labor-saving in production equipment due to its lightweight and high strength. For example, changing conveyor rollers from metal to CFRP can help save energy. On the other hand, there may be issues where surface treatments that can be applied to metal cannot be processed on CFRP. For instance, if the transported items have adhesives or sticky components attached, there may be cases where an anti-adhesion coating is applied to the conveyor rollers. Thanks to surface treatments, a reduction in cleaning time can lead to improved productivity. The ability to apply surface treatments to CFRP materials can enhance the effects in conjunction with material changes. ● Reducing waste and unevenness in parts for CFRP materials Features of surface treatments that can be processed at room and low temperatures ■ Features - Low-temperature processing causes minimal damage to molds and resin molds - There are grades with particularly strong non-stick (release) properties - The effects of the coating last a long time - It can also impart tackiness (a property that makes surfaces less slippery) *For more details, please download the PDF or contact us.

Wear refers to the process in which one or both of two objects in contact and moving against each other become abraded. There are two main types of wear that can occur in manufacturing environments. One is "rough wear," which occurs when surfaces are abraded and eroded due to contact with rough surfaces or particulate matter. The other is "thrust wear," which happens when surfaces adhere due to frictional heat and are worn away by the opposing material. The appropriate surface treatment varies depending on the type of wear. [Selected Surface Treatments] ■ Wear Resistance (Rough Wear) - Urethane Coating ■ Wear Resistance (Thrust Wear) - Bi-Coat *For more details, please refer to the PDF document or feel free to contact us.

■Consultation In the production process of cartridge filters, the adhesion of resin to the heat welding plate used for welding the products has been a problem. The products are completed by thermally welding polypropylene containers and lids, but PP resin tends to cause stringing and adhesion to the welding jigs, negatively affecting the product's airtightness, appearance, and production efficiency. Therefore, the heat welding plates required not only excellent release properties but also heat resistance and thermal durability. ■Background of Coating Selection In the prototype, in addition to the standard fluororesin coating, we proposed a contact area-reducing fluorine coating "TP-855." Since the welding process involved relatively low pressure, the release properties improved, making stringing and adhesion less likely. Additionally, it was used for a relatively long lifespan. ■History and Effects of Coating To further extend the lifespan of the release effect, we considered hybridizing the high thermal hardness CHC series with the contact area-reducing coating. Aiming for even longer lifespan, we proposed "CHC-1311," which balances thermal hardness and contact area reduction. Currently, there is no metal exposure due to wear, and it is being used effectively. If you are facing issues in the heat welding process, please consult Yoshida SKT.

In fluororesin sheet lining processing, there are two methods: "adhesive lining," where sheets made of PTFE or PFA are processed to allow one side to be bonded using a special method and then adhered to the substrate with adhesive, and "loose lining," a processing method like lining pipes where the liner is not bonded to the substrate. Sheet lining can process thicker linings compared to many other fluororesin lining methods. This results in excellent corrosion resistance among various fluororesin linings. On the other hand, the adhesion strength with the substrate depends on the adhesive's bonding power, so it generally does not accommodate use in negative pressure environments. Negative pressure applications can be addressed with other methods such as baked lining or roto-lining. *You can download a document summarizing the details of the lining.

The difference between fluoropolymer and Teflon is the difference between a general name and a trademark. Fluoropolymers include various types such as PTFE, FEP, PFA, and ETFE. Teflon is a trademark of Chemours and is a brand name for some fluoropolymers. Therefore, even if they are referred to differently, such as fluoropolymer coating or Teflon processing, they may refer to the same coating. PTFE was discovered in 1938 by Dr. Plunkett of DuPont in the United States and was later marketed as Teflon PTFE. It later became famous for Teflon coating on frying pans, and the name Teflon became widely known. Currently, the Teflon trademark can only be used in factories that have entered into a licensing agreement with Chemours. Yoshida SKT entered into a contract with DuPont in January 1968 as a Licensed Industrial Applicator.

Teflon coating is applied to frying pans and hot plates to prevent sticking. This explains the causes of peeling and how to address them. ■ Causes of Peeling Teflon is a brand name for fluoropolymer. Fluoropolymer is a type of plastic, making it softer and more prone to scratches compared to metal. The continuous use temperature is also lower, at up to 260°C, compared to metal. Therefore, simply scraping with a metal spatula or scrubbing hard with an abrasive sponge can cause scratches and lead to peeling. Additionally, extreme high-temperature environments, such as dry heating, can cause degradation or decomposition, so caution is necessary. Use a spatula made of resin, clean with a soft sponge, and if using a neutral detergent, it is important to rinse thoroughly. Residual surfactants can make the surface more prone to sticking. ■ Solutions In principle, Teflon coatings and fluoropolymer coatings cannot be partially repaired. Therefore, if it is a frying pan, we recommend replacing it. For industrial parts, reprocessing for peeling may be considered. Please contact us regarding the peeling methods and suitable base materials. Teflon-coated products can be used for a long time depending on how they are used. We recommend utilizing their features effectively.

■Features of PTFE Coating PTFE has the characteristic of having extremely low resistance due to friction compared to other resins. By processing PTFE coating, the static friction coefficient of the substrate surface can be reduced, allowing two objects in contact to be moved with a small force. ■Low Friction of PTFE Coating - Due to the strong atomic bonds within PTFE molecules, the intermolecular forces of the contacting material with PTFE molecules are reduced. - Friction (sliding) causes PTFE molecules to adhere slightly to the contacting material, resulting in sliding between PTFE molecules. - The surface of PTFE molecules has a smooth structure with few irregularities. - The orientation of PTFE molecules makes it easier to alleviate friction resistance. It is believed that the molecular structure influences the low friction coefficient of PTFE coating. *For more details on fluoropolymer coatings, including PTFE coatings, please download the catalog or contact us.*

The coating performance measurement service is for those who want to test the effectiveness of coatings using materials produced in-house, or for those considering the introduction of coatings but struggling with the selection process. At Yoshida SKT, we propose five unique measurement methods for coating performance, which can be difficult to quantify. Please feel free to consult us about preparing sample pieces. = Are you facing any of these issues? = You want to test coatings to prevent labels from sticking to temporary placement platforms or chuck claws in equipment that transports labels and tapes. However, you are unsure about the degree of adhesion between the labels or tapes you use and the coatings, making it difficult to proceed with improvements. In the [Tape Release Force Measurement], you can confirm the degree of peeling by applying adhesive tape to the coated surface and measuring the force required to peel it off. Yoshida SKT's coating performance measurement service allows you to smoothly conduct practical tests by checking the adhesion between the coatings and the materials you use. We also introduce four other measurement methods tailored to your conditions. ▼ For more details, please visit our website ▼

"Die biting" refers to the phenomenon where resin sticks to or gets caught in the mold, causing scratches or defects in the molded products. This can occur when resin adheres to the mold's gates or flash surfaces, or when the mold patterns do not transfer to the surface of the molded products. When die biting occurs, it can lead to a decline in the appearance quality and dimensional accuracy of the molded products, potentially worsening product quality. Additionally, it may necessitate repairs or maintenance of the mold, which can adversely affect productivity. **Methods to Prevent Die Biting:** Surface Treatment: Properly treating the surface of the mold makes it less likely for resin to stick to it. Improvement of Gate Design: By considering the flowability of the resin and the balance of forces during withdrawal, a gate design can be implemented that prevents die biting. Optimization of Molding Conditions: Optimizing molding conditions can make it less likely for resin to stick to the mold. For example, it is important to appropriately set molding conditions such as molding temperature, injection speed, injection pressure, and holding pressure. Mold Maintenance: Proper maintenance can prevent the occurrence of die biting. Effective measures include cleaning the surface, correcting gates and flash surfaces, and using air blow.

■What is corrosion-resistant coating? It is a coating that can protect the substrate, mainly metal tanks and pipes, from chemicals. Corrosion resistance refers to the property of being less prone to corrosion reactions and oxidation. By coating materials that excel in chemical resistance, corrosion resistance can be imparted to the substrate. Coatings that are relatively thick are referred to as "lining," and they are also called corrosion-resistant linings or anti-corrosion linings. Lining materials include resins, rubber, and glass, and in environments that are relatively corrosive or reactive, fluororesins, which excel in chemical resistance and heat resistance, are often chosen. Fluororesins can provide high corrosion resistance by utilizing excellent coating technology to create a pinhole-free finish. ▼ "Protecting the substrate from chemicals!"

■What about the surface of stainless steel? Among stainless steels, the surface of austenitic stainless steel (SUS304) is covered with a passive film, making it resistant to rust in normal environments and maintaining a beautiful luster. However, in specific environments, it may corrode, and when used as machine parts, properties such as slip resistance and wear resistance are required. 【Types of Surface Treatment and Coating for SUS304】 - Electrolytic polishing - Sandblasting / bead blasting - Plating - Teflon coating There are methods like the above to modify the surface of stainless steel. Generally, these methods provide sufficient functionality, but if you want to further enhance durability, slip resistance, and non-stick properties, we introduce coatings that can meet such demands. 'Bicoat,' with its hard film of HV700-900 and the lubricating properties of fluororesin, combines wear resistance, slip resistance, and non-stick properties, making it recommended for those who are not satisfied with conventional surface treatments and coatings.
