Suppressing liquid dripping and positional displacement to achieve stabilization of precise coating.
In the liquid dispensing process, dispensing failures are often caused by liquid adhesion to the nozzle's outer surface, leading to issues such as misalignment, liquid dripping, and stringing. This can result in variations in product quality and an increase in defect rates. NonStick STC suppresses liquid adhesion by forming a low surface energy layer on the nozzle surface, improving the break-off of droplets after dispensing. This is expected to stabilize the dispensing volume and position, contributing to quality improvement in precision coating processes. Additionally, due to its ultra-thin film, the impact on nozzle shape and dispensing diameter is minimized. It can be considered an effective countermeasure when improvements are difficult to achieve through a review of process conditions alone.

basic information
NonStick STC is a thin film, non-stick coating that forms a low surface energy layer on the substrate surface. By chemically bonding fluoropolymer, it achieves high non-stick properties and durability. The film thickness is very thin, at less than 1μm, which minimizes the impact on nozzle shape and dimensional accuracy. Additionally, since it does not require blast treatment, it allows for functional enhancement while maintaining surface smoothness. By suppressing liquid adhesion and improving slip properties, it contributes to improved discharge stability and maintenance.

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.
