The manufacturing process of weather strips involved transporting extruded rubber on rolls while heating and drying it in a furnace. Due to changes in the rubber material formulation for environmental measures and durability, it became necessary to process the rubber at higher temperatures than before, resulting in the rubber becoming sticky immediately after entering the furnace. When a common fluororesin coating was applied to the transport rolls, it was confirmed that the rubber stuck to them like a suction cup. By adopting our "Super TP Coating," we significantly reduced the sticking of the rubber and achieved a relatively soft contact surface. [Case Study] ■ Purpose of surface treatment: Quality improvement, operational stability, reduction of work loss, compliance with safety and environmental requirements ■ Required functions: Non-stick, release properties, long lifespan ■ Treatment adopted: Super TP Coating *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case of surface treatment that improved the liquid drainage of measuring cups. ■Concern In the case of a standard measuring cup, liquid was drained by either tilting it at a steep angle or shaking it by hand. Particularly with heavy cream, the drainage was poor, requiring multiple shakes or the use of a spoon. Initially, we considered Teflon coating, but it did not perform well with heavy cream. ■Request When we received the consultation, the client was using a thin-film fluorine coating from another company, but there were many inconsistencies in the processing, and the liquid drainage was unstable, sometimes good and sometimes bad. ■Coating that solved the issue MRS-014 ■Background of adoption At Yoshida SKT, we produced a prototype of the MRS coating, which is a food-safe type with a thin film. By combining it with a special base treatment, we achieved good liquid drainage even with heavy cream. The ability to pour at a right angle also improved workability. The MRS coating is about 1μm thick, so there is almost no risk of volume error or foreign matter contamination. Additionally, at the World Bartender Championship, the ability to pour at a right angle was well received for making the actions look elegant. *For product details, please refer to the PDF.

When using a household frying pan for a long time, the fluoropolymer coating may peel off or wear down, leading to sticking issues. The fluoropolymer coating can be removed and reprocessed. However, household frying pans are not designed with reprocessing in mind, which brings both advantages and disadvantages. ■ Advantages - The coating of a beloved cooking tool is renewed, restoring the non-stick properties and ease of maintenance similar to that of a new product. - There is no need to buy new equipment, and disposing of the old frying pan is not a problem. ■ Disadvantages - Reprocessing requires high-temperature heat treatment (over 400°C), necessitating the removal of handles made of resin or plastic. (If they cannot be removed, reprocessing is generally not possible.) - A frying pan that has been used for a long time may have corrosion on the metal parts, and even if the coating is reprocessed, it may not return to a like-new condition. - Especially in cases where the metal thickness is thin, reprocessing may cause distortion and deformation. - There may be adverse effects on the exterior, resulting in a poor appearance. As such, reprocessing has many disadvantages as well as advantages, so caution is necessary when it comes to household cooking utensils.

Why does fluoropolymer coating repel water? We will introduce the relationship between surface energy, non-stick properties, and water repellency. ■ The relationship between water droplets and surface energy The reason the surface of fluoropolymer coating repels water is that the surface tension of water acts strongly. The same principle applies to sticky substances. In other words, "difficult to wet = difficult to stick." The action of liquid surface tension is strongly related to the surface free energy of solids. Surface free energy is the force that tries to attract the molecules of the contacting counterpart. Water is a substance with higher surface tension compared to oil. When in contact with a solid that has the same surface free energy, oil tends to spread and wet more easily, while water tends to bead up and is harder to wet. The smaller the surface free energy of the solid compared to the liquid it contacts, and the greater the difference, the more difficult it becomes for the liquid to wet (stick). The surface of fluoropolymer coating has very low surface free energy, which allows it to repel not only water but also oil, making it an effective surface treatment for release purposes due to its low tendency to stick.

Release 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.

■ 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.

We 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! ▼

As 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.

By applying a unique fluororesin coating to glassware such as beakers and flasks, as well as scientific instruments, we prevent glass shattering in the event of falls or accidents, ensuring safety on-site. Additionally, the amount of hazardous chemicals or expensive pharmaceutical raw materials that may scatter is reduced, thereby minimizing the risk of serious accidents or losses. The transparency is higher than that of standard fluororesin coatings, so visibility and measurement of the contents remain unaffected! ■ Features - Excellent adhesion prevents glass scattering - Minimizes exposure and loss of contents - Allows for normal operations with overwhelming transparency ■ Main Applications - Medical institutions, welfare facilities, testing organizations, universities, research institutions, etc. *For more details, please refer to the PDF materials or feel free to contact us.

■Concern The manufacturing process of weatherstrips involved transporting extruded rubber on rolls while heating and drying it in a furnace. Due to changes in the rubber material formulation for environmental measures and durability, it became necessary to process the rubber at higher temperatures than before, resulting in the rubber becoming sticky immediately after entering the furnace. ■Issues It was confirmed that when a common fluoropolymer coating was applied to the transport rolls, the rubber would stick to them like a suction cup. ■Effect of Surface Treatment By adopting our "Super TP Coating," we significantly reduced the rubber's stickiness and achieved a relatively soft contact surface. 【Key Points】 ■Purpose of Surface Treatment: Quality and operational stability, reduction of work loss, compliance with safety and environmental requirements ■Required Functions: Non-stick and release properties, long lifespan ■Adopted Treatment: Super TP Coating *For more details, please refer to the PDF document or feel free to contact us.

■ "Nano Process" refers to - A super-thin film surface treatment technology that coats functional materials with a nano-thin film of less than 1 micron, allowing for surface modification without compromising the original precision and performance by preventing dirt adhesion, sticking of contaminants, and friction resistance. - Since the thickness of the surface treatment is almost negligible, there is no need to design the substrate with film thickness in mind, and it provides effects such as water and oil repellency and non-stick properties. - It enables surface modification of parts across a wide range of industries that require precision. - With a series of developments, it can be adopted for various usage environments and applications. *Hydrophilic surface treatments are also available. 【Examples of Nano Process Adoption】 - Dirt such as sludge adheres to the inner components in high-temperature environments, degrading performance. - Surface modification is desired to prevent sticking on the blades of adhesive devices, but cutting performance must not be compromised. - Coating processing is desired to prevent contamination on precision instruments, but maintaining accuracy is necessary. "Nano Process" is adopted to address challenges that were difficult to solve with conventional non-stick coatings. *For more details, please refer to the PDF materials or feel free to contact us.
