Ultra-thin film fluorine coating for cutting tools | Preserves sharpness, prevents adhesive attachment and wear.
NonStick STC
"Ultra-thin film with a blade edge not rounded to less than 1µm" achieves sharp cutting performance and high non-stick properties! Prevents adhesion to scissors and cutting blades, significantly reducing cleaning time.
This is a technical case study of our unique ultra-thin film, non-adhesive coating "NonStick STC," applied to industrial scissors and various cutting blades for continuous cutting of composite fabrics, adhesive tapes, laminated sheets, and more. It forms a uniform and highly precise functional coating without compromising the original dimensional accuracy and sharpness of the blade edge. **Main Improvement Effects from Implementation** - **Prevention of Adhesive and Glue Adhesion** Thanks to excellent release properties, it prevents adhesives and sticky components that seep out from sheets or fabrics during cutting from sticking to the blade edge. This prevents entanglement with the blade and contamination of the cut surface, stabilizing processing quality. - **Ultra-thin Film Below 1µm That Does Not Compromise Sharpness** Unlike conventional fluoropolymer coatings (thickness of several tens of µm), it functions with an ultra-thin film (sub-micron) of less than 1µm. It can be coated without rounding the blade edge, maintaining sharp cutting performance. - **Reduction in Cleaning Work and Extension of Tool Lifespan** It prevents the accumulation of glue and debris, significantly reducing the need for frequent blade edge cleaning with solvents and line stoppages. It minimizes friction resistance and wear caused by attachments, extending the durability of the cutting tools.

Applications/Examples of results
**Main Application Areas and Materials Processed** ● Adhesive and Processing Tape Field Slitting and cutting processes for double-sided tape, medical tape, and adhesive films. ● Composite Materials and Fiber Field Cutting of glass fiber and carbon fiber composite sheets, resin-impregnated fabrics, and rubber sheets. ● Packaging and Electronics Continuous cutting of laminated boards, label seals, and various resin films. **Problem-Solving Case Study** ● Issue When continuously cutting composite sheets with adhesive using industrial scissors or cutters, adhesive would stick to the blade edge, drastically reducing cutting performance. This resulted in issues such as sheet pulling and surface contamination. Although conventional fluorine coatings were considered, they could not be applied because the thickness of the coating rounded the blade edge, leading to a loss of cutting performance. ● After Implementation An ultra-thin film coating "NonStick STC" was applied to the cutting blade edge. ● Effects and Results: - Dramatic reduction in adhesive attachment to the blade edge while maintaining the initial sharp cutting performance. - Significant reduction in the effort required for solvent-based cleaning and downtime.

Company information
Nikken Coating Industry Co., Ltd. has been a specialized manufacturer of functional coatings for contract processing, earning the trust of customers across various industries for 79 years since its founding. We leverage our processing technology to maximize the properties of fluororesins, such as non-stick, lubricity, and chemical resistance, providing high-performance coatings that directly address customer challenges, including "Thermo Pro Release" for thermal welding processes and "NonStick STC" for blades and precision molds. In recent years, in response to movements regarding regulations on fluorinated compounds (PFAS), "PEEK resin," which is gaining attention as a substitute for fluororesins, has become a focus. Nikken Coating Industry commercialized the world's first PEEK resin coating, "PEEKCOAT," in 1999. Based on the solid knowledge and know-how accumulated over more than 20 years, we are further intensifying our research and development efforts to explore the potential of next-generation PEEK coatings! We aim to be recognized as "the go-to for PEEK coatings" and will continue to lead the way. As "the best partner for functional coatings that builds trust through technology," Nikken Coating Industry will continue to contribute to the creation of high-quality, high-performance products.
