■Chemical Resistance of Fluororesin Fluororesin has high chemical resistance and does not dissolve, swell, or react with most acids, alkalis, and organic solvents. ■Reasons for High Chemical Resistance A major reason for the excellent chemical resistance of fluororesin is its stable molecular structure. Fluororesin is a high molecular polymer with a linear molecular structure formed by the bonding of carbon atoms and fluorine atoms. 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 tightly covered by fluorine atoms in a helical manner. Therefore, it remains inert when in contact with chemicals or solvents, and does not degrade or dissolve as a resin, which means it has excellent chemical resistance. ■Applications of Fluororesin's Chemical Resistance - Various gaskets - Packing materials - Piping and hoses - Storage tanks - Reaction vessels - Heat exchangers *For more details, please download the materials or refer to the link below.*

For preventing the sticking of sticky adhesive substances, which does not work well with Teflon coatings or fluororesin coatings, the following general measures have been taken, but there are limitations. ≫ Silicone release agents These are spray-type agents that can be easily applied by on-site workers and are familiar as release agents for resin molding. → However, they lack durability in their effectiveness, requiring frequent reapplication, and when wiped off with solvents for cleaning, the release agent is also removed. ≫ Surface roughening (physically reducing contact area) By making the surface of the components uneven, it becomes less likely for things to stick. There are many examples where combining this with Teflon coatings enhances effectiveness. → However, there are concerns about the risk of defective products due to the uneven shape being transferred to the product, and the difficulty of wiping or cleaning during maintenance due to the roughness. Our company has further evolved a smooth silicone coating that is effective against sticky adhesive substances and allows for solvent cleaning, tailored to the "troubles" faced on-site. We are currently offering a "feel the effect kit" for free! The "experience kit" can be requested from the official Yoshida SKT website.

■Low Friction and Sliding Properties of Fluoropolymer (PTFE) Fluoropolymers have a low coefficient of friction and are used 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 molecules have the characteristic of extremely low polarity in their 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 Fluoropolymer PTFE - The strong atomic bonds within PTFE molecules reduce the intermolecular forces with the contacting material. - Friction (sliding) causes PTFE molecules to adhere slightly to the counterpart material, resulting in sliding between PTFE molecules. - The surface of PTFE molecules has a smooth structure with minimal irregularities. - The orientation of PTFE molecules makes it easier to alleviate frictional resistance. For these reasons, fluoropolymer PTFE is considered to have excellent lubricating properties. For more details, please download the materials or contact us.

■Corrosion and Insulation of Stainless Steel Stainless steel is known for its resistance to rust, but it can experience galvanic corrosion between dissimilar metals. By coating it with a highly insulating resin to eliminate electrical contact, galvanic corrosion can be prevented. ■Highly Insulating Resins In general, plastics (resins) do not conduct electricity. Among them, resins such as fluororesin and polyimide are particularly excellent in electrical insulation and heat resistance, making them suitable for various applications. ■Cautions for Insulating Surface Treatments By insulating the surface of stainless steel with coatings like fluororesin, it is possible to maintain a state where electricity does not flow through the stainless steel surface. However, such coatings may require high-temperature curing and must be free of pinholes. Therefore, considerations regarding the design of the base material (component) and film thickness are necessary, and it is appropriate to consult a specialized contractor. *For information on the electrical properties of fluororesins, please click "PDF Download" or feel free to contact us.

PTFE (polytetrafluoroethylene) has a very stable molecular structure and excellent chemical resistance. It is also known for its particularly high gas barrier properties among fluoropolymers. This is because PTFE has very low permeability, making it difficult for gases and vapors to pass through. Therefore, it is suitable for use under harsh chemical conditions, such as in chemical plants and semiconductor manufacturing processes. Furthermore, PTFE has high heat resistance and can be used in a temperature range from -200°C to +260°C. This allows it to maintain its properties even under extreme temperature conditions. However, it is important to select the appropriate usage environment, as it may react with fluorine (gas) or alkali metals (sodium, potassium, lithium) under certain conditions. Fluoropolymer lining can form a lining with high gas barrier and chemical resistance properties on the substrate.

By imparting "release properties and slip properties" through surface treatment, we are currently offering free "Coating Sample Books" and "Process Improvement Case Studies" that have actually improved production processes. ■ The cleaning efficiency of adhesives that do not fully solidify is significantly enhanced by a higher level of non-stickiness. For more details on the cases, please download the "Process Improvement Case Studies" and check them out. You can apply for a free trial set of surface treatment samples from the "Related Links." We encourage you to take this opportunity to apply.

CHC is Yoshida SKT's unique coating technology that uses ceramics. By combining ceramics with fluororesin, it is a new type of fluororesin coating that not only provides the usual "non-stick and release properties," but also has "less reduction in film hardness even in high-temperature environments." Currently, we are offering product materials that include a comparison table of physical properties with various coatings and case studies of companies that have solved their issues with CHC. ■Features - Non-stick properties equivalent to PTFE and PFA - High film hardness at temperatures above 200°C (compared to PTFE) *Based on internal testing *For more product details, please see the link below.
