PEEK coating has excellent mechanical strength and chemical resistance, but traditionally it has been difficult to ensure film thickness, with thick films generally being around 300 to 500 μm. As a result, there were limitations in durability in extremely harsh sliding environments, such as sliding parts subjected to high loads. Our company has adopted a layered process that repeats painting and firing multiple times, allowing for thick films of up to 3000 µm. This process achieves stable film formation while minimizing the risk of cracks and peeling due to internal stress and thermal expansion differences. The increased thickness makes it easier to secure wear allowances, contributing to the longevity of sliding and transport components. It can also be applied to applications that were difficult to address with conventional thin-film PEEK coatings.

In components used in chemical environments, the reduction of lifespan due to corrosion and degradation is a challenge. PEEK is a resin with excellent chemical resistance, but conventional coatings have thin film thicknesses, which poses challenges for long-term protective performance. Our PEEKCOAT forms a stable protective layer even in chemical environments due to a thick film of up to 3000µm. It is easier to maintain performance in corrosive atmospheres and under chemical contact conditions, contributing to the longevity of equipment. It is also possible to achieve a balance with wear resistance, making it a suitable surface treatment for harsh environments. We also accommodate the consideration of individual specifications and prototype evaluations. For technical consultations and prototype verifications, please feel free to contact us.

Wear and deterioration of equipment parts can lead to increased maintenance costs and downtime.

It is also applicable to high-durability applications that are difficult to address with conventional thin-film coatings. We also accommodate individual specifications and prototype evaluations. Please feel free to contact us for technical consultations and prototype verifications.

Conventional coatings are thin, which can make post-coating processing and dimensional adjustments difficult. Thick-film PEEK coatings can achieve millimeter-level thickness, allowing for finishing and clearance adjustments through machining after coating. This enables designs that address functional aspects such as ensuring the precision of sliding parts and optimizing contact areas. By combining coating and machining, the design flexibility of components is enhanced, allowing for flexible responses tailored to specific applications. We also accommodate the consideration of individual specifications and prototype evaluations. For technical consultations and prototype verifications, please feel free to contact us.

Conventional PEEK coatings are prone to cracking and delamination due to internal stress and differences in thermal expansion when thickened, which has limited their design to thin films. Our company has achieved a maximum thickness of 3000µm while suppressing these issues through the optimization of the lamination process and material design. With stable film formation, we can now address high-durability applications that were previously difficult to apply. This technology eliminates performance constraints due to insufficient film thickness and expands new application areas. If you have challenges such as "lack of durability" or "considering thickening," please contact us for technical consultation and prototype verification.

In metal printing processes, there are cases where the transport jig used during transfer to the drying oven comes into contact with the printed metal plates, resulting in scratches on the surface and leading to defective products. This is particularly impactful for high-design products, where even minor scratches can significantly affect quality and contribute to reduced yield. Traditionally, measures such as applying varnish or attaching fluororesin tubes have been implemented, but challenges such as increased maintenance labor and the emergence of new printing defects have arisen. PEEKCOAT forms a high-hardness and smooth resin layer on the surface of the transport jig, reducing damage during contact and providing excellent wear resistance, allowing for long-term stable operation. Its implementation has reduced the defect rate to about 1/6 of the previous level, achieving cost savings in the tens of millions of yen annually.

PEEKCOAT reduces friction and snagging during contact due to its high hardness and smooth coating layer, helping to suppress the occurrence of scratches. It eliminates the need for regular maintenance like traditional varnish applications and can also avoid the risk of printing defects associated with fluororesin tubes. Its excellent wear resistance ensures sustained performance even in environments with repeated contact. This surface treatment achieves both quality stabilization and process improvement simultaneously. We support everything from the consideration of optimal specifications based on application and equipment conditions to prototype evaluation. If you are struggling with preventing scratches in the transport process, please contact us for technical consultation and prototype verification.

The metal printing transport fixtures come into contact with metal plates repeatedly, making them prone to surface wear and degradation, which can lead to the occurrence of scratches. PEEKCOAT maintains a stable surface condition over a long period due to its high hardness and excellent wear resistance. Because it is less likely to experience performance degradation from wear, it helps reduce quality variation and contributes to long-term stable operation. Additionally, it leads to a reduction in maintenance frequency and a decrease in the risk of equipment downtime. In actual field applications, both defect reduction and durability have been confirmed, contributing to the overall reliability of the process. When considering surface treatments that emphasize durability, we can propose optimal coating designs tailored to the usage environment and component specifications.

In recent years, the strengthening of regulations on PFAS (per- and polyfluoroalkyl substances) has increased interest in alternative technologies to fluoropolymer coatings. Traditionally, fluoropolymers have been widely adopted due to their excellent properties such as non-stickiness, chemical resistance, and heat resistance. However, moving forward, ensuring compliance with regulations while maintaining performance and cost balance has become an important challenge. In this context, PEEK (polyether ether ketone), a super engineering plastic, is gaining attention as PEEKCOAT. PEEK maintains stable mechanical properties even in high-temperature environments and exhibits excellent wear resistance and chemical resistance, contributing to the longevity of equipment through an approach different from that of fluoropolymers. Particularly in components where wear and contact are repeated, durability often becomes more important than non-stickiness, making PEEK coatings a viable option for such applications.

We also welcome technical consultations and prototype verifications, so please feel free to contact us.

In the manufacturing process of baked goods, the adhesion of dough to molds and baking sheets is a critical issue directly linked to quality and productivity. When release failures occur, it leads to appearance defects such as chipping and deformation of the products, resulting in decreased yield and increased waste loss. Moreover, under harsh usage conditions such as high-temperature baking and repeated cleaning, the deterioration of coating performance exacerbates adhesion problems. Against this backdrop, there is a demand for surface treatments that achieve stable non-stick properties and durability. Biceram, with its high non-stick properties unique to ceramics, suppresses dough adhesion and burning. It maintains stable release properties even after baking, contributing to quality stabilization and improved production efficiency. We can also accommodate specification considerations and prototype responses tailored to on-site challenges. If you are facing issues with release failures or adhesion problems, please feel free to contact us.

In food processing equipment, coating performance that can withstand high-temperature baking and repeated use is required. Common non-stick coatings tend to degrade in performance due to temperature and frequency of use, often necessitating regular reprocessing. Biceram features the high hardness and heat resistance characteristic of ceramic-based coatings, maintaining stable film performance even in high-temperature environments of around 250°C. This allows for the retention of non-stick properties over an extended period, suppressing performance degradation. Additionally, the hard coating is resistant to wear, demonstrating durability even in parts that are used repeatedly. As a result, this contributes to the longevity and stable operation of the equipment. We can propose optimal coating specifications tailored to the usage environment and product characteristics. If you are experiencing challenges with non-stick performance in high-temperature environments, please feel free to consult us.

In food manufacturing, the lifespan of coatings significantly impacts total costs. Whenever non-stick performance declines, re-coating or part replacement becomes necessary, leading to not only costs but also losses due to production stoppages. Biceram offers high durability and non-stick properties, allowing for prolonged use compared to conventional coatings. This can lead to reduced re-coating frequency and extended replacement cycles, contributing to lower maintenance costs. Additionally, its excellent cleanability results in shorter cleaning times and reduced workload. As a result, it simultaneously achieves improved production efficiency and cost reduction. We can provide technical consultations and prototype support, including a review of current costs and potential areas for improvement. Please feel free to contact us.

A certain food processing manufacturer was using fluororesin coating for their baked goods molds, but due to high sugar content in the dough and high-temperature baking conditions, they faced issues with release failures. Initially, there were no problems, but after about three months, the non-stick properties decreased, leading to dough sticking and chipping. Along with the decline in quality, the increased frequency of re-coating became a significant burden. We proposed a ceramic-based coating called "Biceram." With stable film performance and excellent non-stick properties even in high-temperature environments, we aimed to improve the sticking issues. After implementation, the release properties clearly improved, enabling stable production. Additionally, durability increased, extending the usage period to about six months, achieving approximately twice the lifespan compared to before. As a result, the frequency of re-coating decreased, and costs were reduced by about half. We can propose optimal specifications for sites facing similar challenges. We also accept technical consultations and prototype verifications, so please feel free to contact us.

In the label printing process, issues such as adhesive attachment to the receiving part leading to transport failures and positional misalignment are significant factors contributing to reduced yield. This is especially true for labels with high adhesive strength, where conventional fluororesin coatings or plating treatments often do not provide sufficient effectiveness, and cases of recurrence after a certain period are not uncommon. An effective solution to these challenges is our "NonStick Coating." Based on silicone release technology, our unique non-stick coating significantly suppresses the adhesion of label adhesives. Furthermore, by reducing the contact area through the fine structure of the surface, it demonstrates excellent release properties even against strongly adhesive materials. This results in direct improvements in stabilizing label transport, reducing cleaning frequency, and lowering the risk of equipment downtime. It is increasingly being adopted in many workplaces as a countermeasure against adhesive troubles in the label printing process.

One of the most troublesome challenges in the label printing process is "adhesive residue." Particularly with labels that have strong adhesive properties, glue tends to accumulate on the receiving part, leading to transport issues and misalignment. Traditional fluoropolymer coatings may perform well initially, but they tend to lose effectiveness over time. Our NonStick Coating utilizes the excellent release properties of silicone to fundamentally suppress adhesive residue. Additionally, the release components are supplied from within the coating film, maintaining performance over an extended period. This achieves sustained non-stick properties against adhesives. It is an effective solution that supports stable operations in environments struggling with label adhesive residue.

The adhesive that adheres to the label receiving part accumulates over time, leading to increased cleaning work and equipment downtime. Routine cleaning tasks not only increase the workload but also result in decreased production efficiency. NonStick Coating forms a surface that makes it difficult for the adhesive to "stick" and "remain," thereby suppressing the accumulation of dirt. As a result, it significantly reduces cleaning frequency and contributes to improved equipment operating rates. This coating is ideal for sites that want to achieve stable production while reducing maintenance burdens.

Fluoropolymer coatings, widely used as a solution for adhesion problems, may not always be effective against high-adhesion label adhesives. There are also many cases where the adhesive accumulates over time, leading to recurring issues. NonStick Coating utilizes the non-miscibility of silicone to create a surface that is less prone to adhesive attachment. By further optimizing the surface structure, it reduces the contact area and demonstrates non-stick performance that surpasses conventional coatings. It serves as an effective option for challenges that could not be improved with existing measures.

Many of the equipment stoppages in the label printing process are caused by adhesive sticking to the receiving section, leading to transport failures. Even slight adhesion can cause misalignment and blockages, resulting in line stoppages. NonStick Coating fundamentally eliminates the source of trouble by suppressing the adhesion of label adhesive itself. It enhances transport stability and contributes to the realization of a "non-stopping line." It is an effective means for improving equipment reliability in environments that prioritize stable operation.

In manufacturing, coating technology is directly linked to quality improvement and maintenance efficiency. Traditionally, fluoropolymer coatings (PTFE, PFA, FEP) have been mainstream, but recent strengthening of PFAS regulations has led to a demand for environmentally friendly alternative technologies. Our PEEK coating offers high wear resistance and heat resistance, and is PFAS-free, complying with environmental regulations. Although its release properties do not match those of fluoropolymers, it excels in load-bearing and durability for sliding parts. Depending on the application, a focus on sliding properties can utilize fluoropolymers, while a focus on durability can use PEEK, and a hybrid design combining both is also possible. By selecting the coating that best fits the process conditions, production efficiency can be maximized.

PEEK coating has high hardness and is resistant to wear even in sliding parts and high-load environments, allowing for a longer lifespan. The continuous use temperature is approximately 260°C, and it also has high chemical resistance, withstanding acids, alkalis, and organic solvents. In processes where wear resistance is a challenge for conventional fluoropolymer coatings, PEEK demonstrates stable performance. Being PFAS-free, it complies with environmental regulations and helps avoid future regulatory risks. It is an optimal choice for process improvements under high loads and harsh conditions.

PEEK coating is not only an alternative to fluoropolymer but also a next-generation surface treatment that combines wear resistance, heat resistance, and chemical resistance. By organizing the required characteristics of the process, such as emphasis on release properties, load-bearing and high-temperature environments, and compliance with environmental regulations, optimal coating selection is possible. We offer specification proposals and prototype verification tailored to your applications. Please feel free to consult us regarding the applicability in your own processes and considerations for PFAS measures.

With the strengthening of PFAS regulations, there has been a sharp increase in inquiries about wanting to switch to "PFAS-free materials." However, on the other hand, there are not a few cases where selecting surface treatments based on the idea that "anything PFAS-free is fine" has resulted in new problems such as poor release properties, reduced durability, and increased costs. Fluoropolymer coatings are materials that have achieved a high level of performance in heat resistance, chemical resistance, non-stick properties, and low friction. Therefore, simple substitutions may not maintain equivalent performance. The important thing is not to make "PFAS-free conversion itself" the goal, but to advance environmental measures while maintaining the necessary performance on-site. Our company possesses multiple PFAS-free technologies, including PEEK, ceramics, and silicone-based materials, and provides optimal proposals according to the usage environment.

PEEK resin (polyether ether ketone) is a high-performance resin that possesses particularly high heat resistance, mechanical strength, and chemical resistance among super engineering plastics. Its continuous use temperature is around 250 to 260°C, and it can maintain stable performance even in high-temperature environments, leading to its adoption in a wide range of fields such as semiconductors, automotive, medical, and food machinery. In recent years, with the movement towards PFAS regulations, it has also gained attention as an alternative to fluoropolymer materials, and interest is increasing in applications that require "high durability" and "high reliability."

Due to the strengthening of PFAS regulations centered in Europe, there is a growing interest in "non-fluorinated materials" within the manufacturing industry. Among these, PEEK resin, a type of super engineering plastic, is gaining attention. PEEK resin is a material that does not contain PFAS, yet it possesses high heat resistance, wear resistance, mechanical strength, and chemical resistance, making it a candidate for alternative materials to fluoropolymer. However, it cannot completely replace the excellent non-stick and low-friction properties of fluoropolymers, so appropriate selection based on usage conditions is important. This article will explain the relationship between PFAS regulations and PEEK resin, as well as its characteristics as an alternative material.

Amid the strengthening of PFAS regulations centered in Europe, the shift towards "fluorine-free" solutions is accelerating in the manufacturing industry. Our PEEK coating "PEEKCOAT" is a PFAS-free coating made from the PFAS-free super engineering plastic "PEEK resin." ■ PFAS-Free Compliance Contains no organic fluorine compounds, contributing to reduced future regulatory risks and environmental compliance. ■ High Durability and Long Lifespan Possesses high mechanical strength and wear resistance, potentially achieving a longer lifespan in sliding parts, high-load areas, and wear processes. ■ High-Temperature and Chemical Resistance Has a continuous use temperature of approximately 260°C and exhibits excellent resistance to organic solvents, acids, and alkalis. It is gaining attention as a "durability-focused" PFAS-free coating, distinct from the extreme non-stick properties of fluoropolymer coatings. ■ Exhibition Announcement We will be exhibiting at the "Mechanical Element Technology Exhibition Monozukuri World 2026 (Tokyo)" held at Tokyo Big Sight from July 1 (Wednesday) to July 3 (Friday), 2026. We will also introduce PEEK coatings, PFAS-free coatings, and various functional coatings. We sincerely look forward to your visit.

Biceram" is a hybrid high-performance ceramic coating that combines a strong ceramic framework primarily composed of silica (SiO2) with an excellent non-stick silicone release agent, achieved through the application of the sol-gel method (liquid phase process). Since it is a "liquid application and baking" process, it can coat complex three-dimensional shapes and fine uneven surfaces with a uniform film thickness. ■ Extremely high film hardness Conventional fluororesin coatings (with hardness ranging from F to about 2H) are soft and prone to scratching. In contrast, Biceram boasts a high film hardness with a pencil scratch hardness of [9H]. It is resistant to scratches even in harsh environments where metal scrapers, spatulas, and workpieces frequently come into contact, allowing it to maintain its initial coating performance for an extended period. We propose it as a new option to address on-site challenges such as "fluororesin is too soft and gets scraped off quickly" and "release failures caused by scratches.

Amid the tightening global regulations on per- and polyfluoroalkyl substances (PFAS), there is an urgent need to explore "fluoropolymer alternative technologies" in manufacturing. ■ Ceramic Coating "Biceram" This is a surface treatment technology that is completely free of organic fluorinated compounds [PFAS-free]. It complies with Japan's "Food Sanitation Act (Ministry of Health, Labour and Welfare Notification No. 370)" standards, making it safe and secure for use in parts and molds of manufacturing machinery that come into direct contact with food, as well as cooking utensils. ■ Composition of the Coating The technology is based on the "sol-gel method," which produces a dense ceramic solid from a liquid. By incorporating a silicone release agent that exhibits non-stick properties at the molecular level within a robust three-dimensional silica network, we achieved excellent initial release properties and scratch resistance that significantly surpasses that of fluoropolymers, reaching a pencil hardness of 9H. This is ideal for those who want to evaluate alternatives in anticipation of future regulatory tightening and are looking for a safe, scratch-resistant release coating.

Conventional ceramic coatings (such as thermal spraying and CVD/PVD) typically involve large-scale processes that require high-temperature plasma or vacuum equipment, which limits the shapes and substrates that can be coated. ■ Formation of Ceramic Coating Films by Sol-Gel Method Our "Biceram" utilizes the "Sol-Gel method," which is a liquid-phase process that involves applying a liquid (starting material) and then curing it. - A strong coating is formed at a lower temperature (200–250°C) than the usual ceramic sintering temperature, minimizing thermal impact on the substrate. - Due to the liquid process, it can coat complex three-dimensional shapes, fine irregularities, and the inner surfaces of pipes. - The coating itself has a hybrid structure that incorporates silicone release agents within a three-dimensional network of silica (SiO2). In addition to the "uniform applicability" unique to the Sol-Gel method, it simultaneously achieves scratch resistance that surpasses conventional fluororesins with a pencil hardness of 9H and excellent initial release properties.
