◆Yoshida SKT Co., Ltd.◆ NEW Surface Treatment Solution Case Studies Unveiled All at Once!

The production process of CFRP, which involves layering carbon fibers with resin, requires release properties and non-stick characteristics. Surface treatment technology enhances production efficiency! It also addresses the challenges of release agents.

Yoshida SKT offers "coating" and "functional surface treatment" that address concerns such as highly adhesive materials sticking to equipment and components, hindering production or reducing production efficiency. By providing surfaces with the function of being "less sticky," we aim to resolve these issues. 【Improve CFRP production processes with coating from Yoshida SKT】 ■Challenges - Cleaning tools during CFRP autoclave molding is burdensome. ■Solution - Features of optimal coating for cutting blades. ■Features of selectable coatings - Excellent release properties for epoxy resin. - Long-lasting coating effects. - Silicone-free treatment options available. ■Challenges - Release treatment during CFRP molding causes waste and unevenness. ■Solution - Features of high-release surface treatment. ■Features of selectable coatings - Low-temperature treatment minimizes damage to CFRP (mold). - Particularly strong grades with non-stick (release) properties. - Long-lasting coating effects. - Can also provide tackiness (properties that make surfaces less slippery). *For more details, please download the PDF or contact us.

CFRP, essential for the labor-saving and lightweighting of production equipment. Surface treatment possible even for materials with low heat resistance! Achieving non-stick properties, release properties, and wear resistance through coating.

To prevent noise in production sites and to reduce labor and weight of equipment, switching from metal to lightweight and high-strength CFRP materials is effective. However, changing materials is not always beneficial. In actual production environments, there may be challenges such as, "Once we switched to CFRP rollers, we could no longer perform the surface treatment to prevent adhesion." ■ With Yoshida SKT, improvements can be made even with CFRP rolls and jigs through coating. 【Effects of Coating on CFRP Rolls】 - Adhesive adhesion measures can be implemented, making cleaning easier. - No adhesive residue, eliminating negative impacts on products. - No line stoppages, improving production efficiency. ◆ Coatings Used ◆ ■ Super CTT Coating (Silicone-based contact area reduction coating) 【Features】 - Release properties - Cushioning properties - Tackiness ■ Super Alloy Coating (Flexible alloy coating) 【Features】 - Release properties - Slipperiness - Wear resistance; hardness: HV600 *For more details, please download the PDF or contact us.

Achieving high-speed transport with robots. Improving adhesive troubles that hinder automation with fluorine and silicone-based release coatings.

■Sites Requiring Surface Treatment - Due to adhesion to transport claws and placement platforms for transported items, it has been difficult for grasped items to be released, hindering automation on the line. - Transport processes involving resin parts and hot melt adhesives before they cool and solidify, as well as label adhesive areas and food, are in a state that easily leads to sticking. ■Points of Innovation - By applying the appropriate coating, it is possible to prevent sticking of transported items. - Adhesion issues during transport are not easily resolved through soft solutions like teaching, and even if a release agent is applied to specific areas, its effectiveness can diminish quickly depending on the usage environment, necessitating frequent reapplication and increasing manual labor. In contrast, coatings improve sticking efficiently, have high functional durability, and expand the areas where robots can operate in fields requiring automation. ■Examples of Coatings for Improving Robot Transport Adhesion Issues - Bi-Coat(R) - MRS Coating (Silicone Coating) - Fluorine-based Silicone Convex Coating - Teflon(TM) Fluororesin Coating *For more details, please download the PDF or feel free to contact us.

What types of fluororesins are suitable for applications such as non-adhesiveness, slip properties, and corrosion resistance? It is necessary to consider the characteristics and properties of the resin, as well as the selection of processing methods.

**Representative Types** ■ PTFE (Polytetrafluoroethylene) It has the highest continuous use temperature of 260°C and excels in non-stick and low friction properties. ■ PFA (Perfluoroalkoxyalkane Polymer) It has a low melt viscosity and can achieve a continuous coating with fewer pinholes than PTFE. It is the best-performing fluororesin for high-temperature corrosion resistance. ■ FEP (Perfluoroethylene Propylene Copolymer) An improved resin of PTFE, it has a lower continuous use temperature than PTFE but can achieve a smooth coating with fewer pinholes through sintering. ■ ETFE (Ethylene-Tetrafluoroethylene Copolymer) Due to its excellent mechanical properties, it is highly resistant to wear and is often used for anti-corrosion applications. ■ Modified Types ◎ High-temperature modified type ◎ Low-temperature modified type **Representative Processing Methods** ○ The enamel of fluororesin is applied using a painting machine or manually. ○ Fluororesin powder is applied using electrostatic or special painting machines.

Case study of surface treatment solutions in the electroplating process of electronic components! Introducing a successful case of cost reduction through improved adhesion of plating and better drainage of plating solution.

Here is an example of preventing plating adhesion to jigs used in the plating process. ■Concern In the process of applying electroplating to electronic components, plating was adhering to the jigs used to secure the products, resulting in time and costs for the peeling process. Additionally, when plating adhered, the jigs tended to deteriorate more easily, leading to an increased frequency of replacements. ■Coating Effect By providing insulation through our "fluororesin coating," the amount of plating adhesion to the jigs was significantly reduced. It also demonstrated excellent corrosion resistance, providing protection from plating solutions containing acids and alkalis. Furthermore, the lifespan of the jigs improved, and the amount of plating solution taken out was reduced. Our customers were pleased with the successful cost reduction. 【Key Points】 ■Purpose of Surface Treatment: Quality and operational stability, reduction of replacement and material costs, compliance with safety and environmental requirements ■Required Functions: Non-stick and release properties, rust and corrosion resistance, electrical properties ■Adopted Treatment: Fluororesin Coating (Teflon Coating) *For more details, please refer to the PDF document or feel free to contact us.
