We would like to introduce a case of surface treatment for device components that apply resist liquid to precision substrates. ■Consultation In the process of applying resist liquid to a thin film-like substrate, there was a consultation regarding the resist liquid adhering to the suction fixture during the application process to the precision substrate. ■Concern In the process of applying resist liquid to a thin film-like substrate, a problem arose where the resist liquid adhered to the suction fixture, causing it to stick to the next substrate being transported. The adhesion of resist liquid to the substrate leads to product defects, necessitating an increase in the cleaning frequency of the transport fixture, which hindered productivity. ■Request To solve the problem, we initially tried prototyping with Teflon™ coating, but the slight surface irregularities of the coating transferred as patterns onto the thin substrate, resulting in product defects. A surface treatment that balances precision and prevents the adhesion of resist liquid was necessary for problem resolution. 【Issues to be resolved】 - Adhesion of resist liquid - Cleaning time - Variability in coating thickness ■Adopted Coating 'NanoProcess® TC-10' *For detailed solutions, please download the PDF or contact us.

Rubber is an essential material in our daily lives. It is used in various situations, not only in household goods but also in automotive parts, PC components, the chemical industry, and the medical field. Unlike resins and metals, rubber has elasticity. Additionally, it excels in waterproofing, cushioning, vibration absorption, and tackiness, making it beneficial for applications such as tires, sealing materials, rubber gloves, rubber hoses, roofing materials, and soundproofing materials. On the other hand, rubber has its disadvantages, such as dissolving in solvents, hardening due to ultraviolet rays or aging, and having a surface that can be slippery. Surface treatment of rubber can help improve these disadvantages. For example, by applying surface treatment to non-slip rubber, it can become easier to handle, facilitating installation and preventing sticking, thus enhancing convenience. It can also be protected from dissolving in certain solvents. Surface treatment of rubber requires confirmation of various conditions. For more details, please download the PDF or contact us.

We would like to introduce a case where we solved the sticking trouble of the melt film that could not be resolved with fluororesin coating. ■ Background of the Consultation The consultation was regarding a tray sealer that covers plastic trays with film. In the thermal fusion process of sealing film onto plastic containers, the heating plate is heated to over 100°C, causing the surface of the film to melt. Initially, the heating plate was coated with fluororesin to prevent the film from sticking. ■ Background of Coating Selection The material of the film and the temperature at which it melts were causing product defects due to sticking to the heating plate. Additionally, small holes were drilled in the heating plate for vacuuming the film, which limited the options for coating. ■ Coating Adopted "TP Coating" ■ Adoption Background and Effects To accommodate many conditions, we proposed a release-type coating that excels in release properties compared to the current coating and does not hinder vacuuming, while also reducing contact area. The "TP Coating," which has good release properties and does not affect vacuuming, was adopted. *For more details, please refer to the materials or contact us directly.

■Concern In the heat plate welding of polypropylene sanitary products, thread pulling is likely to occur, making a non-stick (release) coating on the heat plate essential. The customer was using a PFA coating, but it deteriorated quickly, requiring the heat plate to be replaced in about a week. ■Background In this case, where repeated contact/release with components occurs at high temperatures, the effectiveness of the coating diminished rapidly. Replacing the heat plate and reprocessing the coating requires adjustments to the equipment and preparation of spare parts. A coating that excels in non-stick properties and lasts longer in high-temperature environments was needed. ■Adopted Coating FSR (Fluoro Super Release) HR-372AP ■Adoption Process and Effects Yoshida SKT prepared several samples, including the "FSR coating," which was developed with the concept of excellent release properties at high temperatures. Before the actual machine test, we confirmed the release properties of these samples at our company, and it was decided to conduct a practical test with the "FSR coating," which has a proven track record in high-temperature environments. The release effect lasted over five times longer compared to the previous PFA coating. The lifespan of the coating was excellent, and it was adopted.

■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.

Plastic is lightweight and easy to mold, making it suitable for various parts. On the other hand, unlike metals, it is weak against heat, and processing methods involving heating are limited. The characteristics that appear on the surface of plastic vary depending on the type of material, so to change these characteristics, it is necessary to change the material. If you want to change only the surface characteristics while keeping the material the same, surface treatment for plastic can be helpful. For example, when making chuck jaws from plastic material to reduce weight, the surface may be slippery, and you may want to enhance grip. You may also want to give the surface of plastic material conveyor rollers a property that makes them less likely to stick. Surface treatment can address such requests. Surface treatment can improve functionality by making the plastic surface less slippery or creating a surface that is less likely to stick. Surface treatment for plastic requires confirmation of various conditions. For more details, please download the PDF or contact us.

■Consultation This was a consultation regarding the process of thermally welding filter cases to products. We create products by thermally welding polypropylene containers and lids, but PP resin tends to cause stringing and adhesion to the heating plates, which negatively impacts the product's airtightness, aesthetics, and production efficiency. Therefore, it was necessary for the thermal welding plates to have release properties, heat resistance, and durability. ■Background for Coating Selection We proposed fluororesin coatings and reduced contact area fluorine coatings during prototyping. Since the operating pressure is relatively low, the release properties improved, making stringing and adhesion less likely, allowing for relatively long service life. ■History and Effects of Coating To achieve even longer service life, we proposed "CHC-1311," which balances heat hardness and reduced contact area. After practical testing, it was adopted, resulting in reduced metal exposure due to wear, allowing for extended use. If you are having trouble with thermal welding jigs, please consult Yoshida SKT.

■Development Background of Thin Film Fluororesin Coating "10under" Fluororesin coatings are sometimes requested to be processed in thin films of around 10μm when dimensional stability of the substrate is a priority. However, in the case of standard fluororesin coatings, a thickness of at least 20-50μm has been 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 with a different coating structure. However, there were challenges with the modified type not being able to deliver the necessary functions. Yoshida SKT has worked on development to solve these challenges, resulting in the creation of the "Thin Film Fluororesin Coating '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.*

Here, we will introduce the measurement inspection of Teflon coating thickness. When you consult about Teflon coating, if a thickness is agreed upon during the meeting, we will conduct a thickness measurement inspection during the post-processing inspection process to confirm whether the thickness has been processed according to the meeting or the order form. ■ Unit of Thickness In coating thickness measurement, the unit commonly used is "μm (micrometers)" = one-thousandth of a millimeter. ■ Specifications of Thickness The thickness varies depending on the specifications and applications. For fluororesin coatings, it is often around 20-50μm for general purposes and more than 300μm for corrosion-resistant applications. ■ Measurement Method In thickness measurement inspections, a thickness gauge is primarily used for confirmation. This method is a non-destructive type of inspection that does not damage the coating. The thickness gauge typically measures the thickness of the coating by pressing a probe, known as a "probe," vertically against the surface of the coating processed on the metal substrate. *For more details about the thickness measurement inspection, please visit our website via the link or contact us.

■What is Blast Treatment? Blast treatment is a surface treatment method that involves spraying blast materials (various types of abrasives) onto the surface of a product using compressed air, to remove rust and dirt from the substrate surface. ■Surface Preparation for Coating Surface preparation by blasting not only cleans the surface but also increases the surface area through roughening, which enhances the anchoring effect and significantly improves adhesion during coating processes. Therefore, it is suitable for preparing surfaces for many coatings and is commonly used in pre-treatment. Additionally, blasting can improve the wettability of paints, making it optimal for surface preparation for painting as well. To fully realize the performance of coatings, surface preparation is a crucial step. At Yoshida SKT, we select blast materials and treatment methods suitable for coatings and substrates, and we process Teflon coatings and fluororesin coatings. *For more details, please click the link below or feel free to contact us.

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.

Fluoropolymer (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. ■ Insulation properties of the representative fluoropolymer, PTFE PTFE has very low volume resistivity and surface resistivity, making it a material that is difficult to conduct electricity. The dielectric strength of PTFE with a thickness of 3.2mm is 19KV/mm. The dielectric strength of PTFE is equivalent to that of PEEK at 19KV/mm and superior to that of PPS at 15KV/mm. *For more details, please visit the official website via the link below or feel free to contact us.
