Free membership registrationRelease properties refer to the characteristic of materials or products that allows them to be easily removed from molds or forming tools without sticking. This property is important in the manufacturing process and affects product quality and production efficiency. ■ Methods to Improve Release Properties By applying a release agent to the surface, a thin film is created between the mold and the product, preventing adhesion. Silicone and fluorine-based release agents provide excellent release properties for many materials. ■ Resin Coating Applying a resin coating to the surface exhibits non-stick properties, making it easier to remove the product. Fluororesin coatings are commonly used. ■ Metal Plating For example, chrome plating has high hardness and is less reactive with other substances, aiding in product removal. Fluororesin-containing types of plating also exhibit non-stick properties. ■ Surface Roughness Adjustment By designing the surface with fine uneven structures, the contact area is reduced, thereby decreasing adhesion. As mentioned above, there are various methods, but we will introduce surface treatment technologies and coatings that are particularly effective in enhancing release properties, reducing product defects, and improving productivity.

Free membership registrationWe would like to introduce a case where the adhesion of decorative sheets to molds during transfer was resolved. Decorative sheets with adhesive are set onto parts using molds and are then vacuum transferred. During this process, it was observed that excess sheets, aside from the parts, adhered to some parts of the mold. To prevent the adhesion caused by the adhesive of the decorative sheets, surface treatment for the molds was explored. By adopting our "Bicoat," significant improvements in adhesion prevention were achieved. The adhesion of decorative sheets was reduced to nearly zero, resulting in a level of effectiveness that satisfied our customers. [Key Points of the Case] - Purpose of Surface Treatment: Quality and operational stability, realization of development needs, reduction of replacement and material costs - Required Functions: Non-adhesive, release properties, long lifespan - Treatment Adopted: Bicoat(R) *For more details, please refer to the PDF document or feel free to contact us.

Free membership registration■ The "Non-Stick Property" of Fluoropolymer Non-stick property refers to the characteristic of being easy to release and not adhere, or to adhere less, even to strongly adhesive substances. For example, fluoropolymers excel in water and oil repellency, have a large contact angle, and possess a property of being difficult to wet due to their molecular structure. The measure of wettability, "critical surface tension (γc)," is extremely low for fluoropolymers, making it easy for liquids to be repelled and difficult to wet. Coatings that utilize this functionality are effective for release applications, applications where adhesion needs to be minimized, and for simplifying cleaning. 【Reference Data on Non-Stick Property】 ■ Contact Angle of Water (°) PTFE ... 114 PFA ... 105-110 FEP ... 115 ETFE ... 96 ■ Contact Angle of n-HD (°) PTFE ... 34-45 PFA ... >45 FEP ... 41-45 ETFE ... 28 ■ Surface Free Energy of Solids (dyn/cm) PTFE ... 18.5 PFA ... 17.8 FEP ... 17.8 ETFE ... 22.1 *For detailed information on non-stick properties, please download the PDF or contact us.

Free membership registration"Non-stick" refers to the property of being easy to release from strongly adhesive materials, meaning it either does not adhere or adheres with difficulty. For example, fluoropolymer resins excel in water and oil repellency, have a large contact angle, and possess a property of being difficult to wet due to their molecular structure. The measure of wettability, known as "critical surface tension (γc)," is extremely low for fluoropolymer resins, making them resistant to liquid adhesion and difficult to wet. Coatings that leverage such functions are effective for release applications, applications where adhesion needs to be minimized, and for simplifying cleaning. 【Selected Coatings (Partial)】 ■ Release properties, high hardness, dimensional stability (durable parts, molds) - Bi-Coat ■ Resin release at high temperatures - FSR Coating ■ Prevention of adhesion of high-viscosity materials - Adhesive Release Coating - CTT Fabric Sheet - MRS Coating (Silicone-based coating) *For more details, please refer to the PDF materials or feel free to contact us.

Free membership registrationWe would like to introduce a coating that can solve the problems caused by adhesive from packaging films adhering to cutter blades. In one packaging machine, packaging films with adhesive frequently adhered to the cutter blades, resulting in poor cutting performance and film sticking to the blades, causing misalignment and necessitating line stoppages. This issue prevented us from achieving the production quantities calculated from the takt time. Initially, a release agent was applied, but its effects did not last, requiring repeated applications. Therefore, we adopted the silicone-based coating "MRS Coating." The coating eliminated adhesive adhesion, and since the processing temperature is below 250°C, there were no concerns about blade dulling. Additionally, the 1-micron thin film maintained the sharpness of the blade edge. [Key Points of the Case] - Purpose of Surface Treatment: Quality improvement, operational stability, speed enhancement, compliance with safety and environmental requirements - Required Functions: Non-stick, release properties, long lifespan - Treatment Adopted: MRS Coating (Mold Release Silicone) ▼ Free samples of improvement cases for the cutting process and trial sets are currently available on the site below! ▼

Free membership registrationAs a problem with the packaging machine, the adhesive film was sticking to the cutter, impairing its sharpness and causing misalignment of the film. This resulted in the production line being halted, leading to a situation where production could not proceed as planned. Initially, a release agent was used, but its effect was temporary, requiring frequent reapplication. The introduction of "MRS Coating" resolved the sticking issues. MRS Coating can be processed at temperatures below 250°C and maintains sharpness due to its 1-micron thickness. In this case, MRS Coating achieved stabilization of quality and operation, improved work speed, and addressed safety and environmental requirements. MRS Coating realizes non-stick properties and has a long-lasting effect. [Key Points of the Case] ■ Purpose of Surface Treatment: Stabilization of Quality and Operation, Speed Improvement, Safety and Environmental Compliance ■ Required Functions: Non-stick and Release Properties, Long Lifespan ■ Treatment Adopted: MRS Coating (Mold Release Silicone) ▼ Free samples and case studies on improving cutting processes are available on the website below! ▼

Free membership registration■What are the issues with release agents? Release agents are known to be applied in industrial fields to improve the separation of molded products from molds. In addition to facilitating mold release, release agents also need to have properties that make them resistant to degradation from heat during molding and minimize contamination of the mold. Silicone is often used as a release agent because it has high heat resistance, does not easily degrade with repeated heating during molding, has low surface tension which provides good wettability to the mold, and can reach every corner of the shape. While silicone release agents have excellent effects, they can also impose a burden on the working environment, increase the effort required for mold cleaning, and lead to variations in the amount applied by workers, which may negatively impact the final product. ■Silicone Coating Technology Silicone coating technology balances release properties and maintenance, leading to solutions for release agent issues. ▼For more details about the coating, please click the URL below or contact us.

Free membership registrationWe would like to introduce a case of surface treatment that solved troubles in the application process of hot melt adhesive. A certain customer's product is manufactured by bonding a surface material (film) with insulation material using hot melt adhesive. Since the product with applied adhesive could stick to the conveyor rollers during transport and cause entanglement, a petroleum-based release agent was previously applied to the rollers as a countermeasure. However, complaints arose in the market due to the residual release agent on the product. There was a need for a countermeasure to prevent roller entanglement that could replace the application of the release agent. Therefore, we adopted our 'Super Alloy Coating'. After approximately two years of use, there have been no troubles such as roller entanglement, and of course, complaints regarding the adhesion of the release agent in the market have also disappeared. [Key Points] - Purpose of surface treatment: Quality and operational stability - Required functions: Non-stick, release properties, wear resistance - Treatment adopted: Super Alloy Coating *For more details, please refer to the PDF document or feel free to contact us.

Free membership registration◆What is Super Alloy Coating◆ Super Alloy Coating is a coating system that covers soft substrates such as plastics and rubber, as well as the surfaces of lightweight metals like aluminum and thin sheets, with an alloy that has a hardness of Hv 600 or higher, while also possessing flexibility. It effectively prevents dirt on various manufacturing equipment and components, reduces maintenance tasks such as the peeling of adhesive materials, and demonstrates excellent mechanical strength and durability. The surface of the coating has rounded protrusions, which minimizes scratches on contact objects. Additionally, despite being a metal coating, it has the ability to conform to slight bends and can accommodate curved surfaces. It allows for excellent release properties from adhesive materials and strength while maintaining the flexibility of the processed material. 【Features】 ■ Non-stick convex surface formation ■ Alloy coating with Hv hardness of 600 ■ Excellent mechanical strength and durability ■ Minimization of scratches on contact objects ■ Usable on various materials *For more details, please refer to the PDF document or feel free to contact us.

Free membership registrationThere is an electrical insulation coating with high electrical resistivity that has the function of blocking electric current. Fluororesin has high insulation properties, with a volume resistivity of Ω·cm or more, and its arc resistance is more than three times that of general-purpose resins, making it superior and stable in various electrical environments compared to other resins. On the other hand, if the coating surface is prone to charging, leading to issues such as the adhesion of foreign substances due to electrostatic attraction or electrostatic disasters, you can select a fluororesin coating with antistatic properties. [Coatings Being Selected] ■ Electrical Insulation - Fluororesin Coating (Teflon Coating) ■ Antistatic Properties - Saflon - Saflon AP+ *For more details, please refer to the PDF document or feel free to contact us.

Free membership registrationWear refers to the phenomenon where 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 type is "rough wear," which occurs when surfaces are abraded and eroded due to contact with rough surfaces or particulate matter. The other type 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 Coatings] ■ 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.

Free membership registration■ We respond to improvement requests in the production field with surface treatment. ● Stabilization of quality and operation ● Reduction of material costs ● Reduction of work loss ● Speeding up ● Compliance with safety and environmental measures ● Realization of development needs For example, to stabilize quality and operation, we clarify the necessary functions, such as seeking "non-stick properties" to minimize material adhesion to equipment. The functions required on-site are not singular but are interrelated in a complex manner. To maximize the desired effects, it is essential to arrive at optimally customized surface treatments through broad technical considerations. ■ Yoshida SKT translates the desired functions into necessary functions through surface treatment. ● Non-stick properties ● Slipperiness ● Chemical resistance ● Heat resistance / Cold resistance ● Water and oil repellency ● Hydrophilicity ● Wear resistance ● Electrical properties ● Static electricity prevention ● Dimensional stability ● Coating surface roughness adjustment Yoshida SKT proposes optimal surface treatments based on a wide range of coating materials and unique technologies. In cases where the desired effects are not achieved with fluororesin coatings (Teflon coatings), we investigate the causes and derive treatments with the appropriate functions added.
