Prevent breakage of molded products during extraction! Fluoropolymer × PEEK coating for molds.
PEEKCOAT Plus
"Resin Sintering Molding" eliminates product damage and yield reduction due to wear. Achieves smooth extraction with the non-stick properties of fluoropolymer and the wear resistance of PEEK!
In the resin sintering molding (press molding) process for filter filtration bodies with complex uneven shapes, smooth extraction from the mold and stable product quality are extremely important challenges. Conventional fluoropolymer coatings could not withstand the harsh friction caused by fiber-reinforced resin materials, leading to frequent issues such as "decreased release and slip properties," "product extraction breakage," and "reduced yield due to debris accumulation" due to early wear. Our "PEEKCOAT Plus" is a hybrid coating that uniformly disperses fine particles of the ultra-high-performance resin PEEK within a fluoropolymer film. 【Product Features and Introduction Benefits】 ● High Non-Stick and Sliding Properties Thanks to the characteristics of the base fluoropolymer, it minimizes product sticking and friction resistance during extraction. ● Gentle Coating for Counter Materials and Products By using hard PEEK resin particles as reinforcement, it does not damage delicate molded products, unlike inorganic fillers (such as ceramics). ● Significant Improvement in Yield It prevents product breakage due to excessive load during extraction and strongly supports the continuous production of high-quality molded products.

Applications/Examples of results
【Applicable Uses and Target Areas】 ● Resin sintering molding molds, heating press molding molds (filter filtration bodies for dust collectors, etc.) ● Resin molding molds with complex corrugated or bellows-like uneven shapes ● Molding jigs and cavity surfaces with high wear of coating films, such as fiber-blended resins 【Case Studies and Adoption Results】 ● Target: Manufacturers of sintered molding for dust collector filter bodies ● Challenges - Fluororesin-coated molds wore out in less than a month, causing delicate filtration bodies to break due to resistance during extraction. - Residue from thermally degraded materials adhered to products, significantly reducing yield. - Even when switched to a wear-resistant grade of fluorine coating, the lifespan was limited to about 3 months. ● Effects - The introduction of "PEEKCOAT Plus" maintained excellent release and sliding properties at a high level for an extended period. - Instances of snagging and breakage during extraction were drastically reduced, leading to a remarkable improvement in yield. - Compared to the wear-resistant grade of fluororesin coating (about 3 months), the mold lifespan was significantly extended to "about 1 year."
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.
