We will introduce Yoshida SKT in a video of about 2 minutes. Please take a look.

Yoshida SKT began fluororesin processing in 1963. In 1968, it signed a licensing agreement with DuPont in the United States. For half a century since then, we have pursued surface treatment functions, starting with Teflon™ fluororesin coatings. In response to customer needs, we have also developed numerous original coatings. At Yoshida SKT, we can accommodate a wide variety of substrates and offer proposals from hundreds of types of coating materials. This expands the range of coatings that customers can choose from. In addition to functions such as "reducing adhesion of sticky substances" and "improving slip," we respond meticulously to the diverse needs and environments of our customers, such as "requiring precision" or "requiring heat resistance," to achieve reliable effects. We also provide test pieces that can be tried on-site for support. For cost reduction in manufacturing, strengthening competitiveness, and creating a welcoming environment on-site, please feel free to consult with us first.

A fluorine coating with excellent release properties that hardly sticks to duct tape! It solves problems in food transport lines and resin film manufacturing lines.

The "Super TP" release coating system improves the "release ease" of adhered materials through a technology that roughens the coating surface to a convex shape, thereby reducing the contact area. This achieves a level of non-stickiness that cannot be obtained with conventional Teflon or fluoropolymer coatings. It demonstrates remarkable release properties (anti-adhesion) even with highly adhesive substances such as unvulcanized rubber, adhesive tape, and hot melt adhesives. If you have been struggling with transportation issues or molding defects caused by adhesive materials, or if you need to reduce maintenance on molds, transport chutes, or rolls, please feel free to consult us. ■ Features - Non-stickiness and release properties that surpass fluoropolymer coatings - Anti-adhesion to adhesive materials like molten resins and adhesive tapes - Slip and lubrication properties through a special technology that roughens the coating surface - Compatible with silicone-free requirements (TP series, Super TP series) - Smooth release - Slippery (lubrication) (TP series) *For more details, please refer to the catalog or contact us directly.

• Coating Agent

Prevents "charging" of fluororesin coatings and reduces static electricity troubles! Also reduces adhesion caused by static electricity.

"Safron(R)" is an antistatic fluororesin coating that enables static electricity elimination by allowing charges generated on the coated surface to flow to the base metal or ground. It reduces static electricity problems caused by fluororesin coatings and provides functions such as "preventing adhesion," "enhancing slipperiness," and "improving corrosion resistance." Additionally, it improves production efficiency in various settings by preventing product issues caused by material sticking and making the cleaning of adhered substances easier. [Features] - Antistatic properties of the coated surface - Excellent release from adhesives, preventing or making adhesion difficult - Improved lubricity due to the low friction coefficient of the fluororesin coating - Prevents poor flow and clogging in transport guides, chutes, pipes, etc. by processing them - Protects tanks and stirring blades that come into contact with chemicals, enhancing safety and durability *For more details, please refer to the PDF document or feel free to contact us.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact on the base material. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.
