We will be exhibiting at the Adhesive and Bonding Technology Exhibition 2024 held on May 24, 2024.

This is a surface treatment technology that dramatically improves the adhesion of fluororesin films and polyimide films, which have been considered difficult to bond until now.

At Kawamura Industries, we apply plasma treatment to films, metal foils, non-woven fabrics, and more, performing surface modification such as hydrophilization and hydrophobicity. This process significantly improves the adhesion of various films and allows for the removal and purification of organic substances from the substrate surface. It can effectively remove residues such as rolling oils that are difficult to completely eliminate with wet cleaning. Additionally, it is possible to bond various materials together without the use of adhesives. **Features of Kawamura Industries' 'Vacuum Plasma Treatment':** - Dramatically improves adhesion - Effectively removes rolling oils and organic substances, purifying the surface - Allows for adhesive-free bonding of various materials - Selects suitable gas types and plasma treatment conditions for each project - Treatment effects last for an extended period - Continuous processing is possible with roll-to-roll technology *For more details, please refer to the PDF document or feel free to contact us.*

The "vacuum hot press," which can also perform surface treatment in the previous process, and the "coating" technology for metal foils are suitable for the processing of electronic materials such as substrates for 5G and base materials for planar heating elements!

Kawamura Industries develops and manufactures materials for electronic applications and provides associated processing technologies. We will introduce technologies that have been adopted for substrates for 5G and materials for planar heating elements. 【Our Technology: Electronic Materials - Strengths of Vacuum Hot Press Coating Technology】 ■ Vacuum Hot Press In prototype and mass production using vacuum hot pressing, we can press without adhesives, allowing us to better utilize the inherent properties of the materials. (Note: We can also accommodate laminated products with adhesives.) - We have a large number of pressing machines, capable of handling various sizes and temperatures. - There are pressing machines installed in a cleanroom environment. ■ Resin Coating on Metal Foil Although we operate in a contract processing format, we can combine "metal foil + high-temperature treatment." - Our coating drying oven can handle temperatures up to 260°C, allowing for the drying of high-boiling point solvents. - We can also accommodate polyimide coating with a high-temperature curing oven that can handle up to 400°C. Including material procurement, we provide consistent support from small lots and prototypes to mass production, so please feel free to contact us. * We are currently publishing an introduction document summarizing what Kawamura Industries can do! You can view it immediately from [PDF Download].

• Joining and fastening materials

Presentation of 4 technical introduction materials: We respond from prototyping to mass production! We also support material procurement. We can accommodate electronic materials that require high functionality, such as those for 5G products.

At Kawamura Industries, we create and provide electronic materials with various functions by integrating slit processing, plasma surface treatment, sputtering processing, thermal lamination, and more. We can handle everything from prototyping to mass production, including material procurement. We also welcome inquiries for small lot requests. 【Our Technologies】 ■ Slit Processing With about 50 years of extensive experience, we can accommodate slit widths from 2mm to 2,000mm. We can process not only in clean rooms but also in yellow rooms. ■ Plasma Surface Treatment Effective for improving the adhesion of low-adhesion films like fluorine films. Our roll-to-roll equipment allows for rapid mass production startup. ■ Thermal Lamination We have a vacuum thermal press capable of handling high temperatures up to 400°C within a clean room. Our laminating machines can also operate in a clean environment from the preparation stage. ■ Sputtering Deposition We possess roll-to-roll equipment. In collaboration with partner companies, we can also perform electrolytic copper plating on sputtered films using roll-to-roll methods. *You can view technical documents and introductory materials regarding the above processing technologies from the "PDF Download" section. Please feel free to contact us with any inquiries.

It is a material with excellent heat resistance, oil resistance, and hydrolysis resistance, eliminating the need for adhesives. Suitable for insulation applications in EV/HEV vehicles!

Kawamura Industries' "Namil" is a material that is directly bonded without the use of adhesives, thanks to our unique plasma surface treatment and thermal lamination technology. Since it is produced through a process that does not use any adhesives or solvents, there are no emissions of volatile organic compounds (VOCs), contributing to the reduction of environmental impact on the Earth. By using aramid paper on both sides, we enhance heat resistance and varnish impregnation, and by using PPS film for the intermediate layer, we improve hydrolysis resistance. It is also possible to produce a high heat-resistant grade using polyimide film for the intermediate layer. **Features of Kawamura Industries' "Namil":** - Excellent heat resistance due to the absence of adhesives - Thin and excellent thermal conductivity due to the absence of adhesives - Superior varnish impregnation due to the use of aramid paper on the surface - Excellent oil resistance and hydrolysis resistance. *For more details, please refer to the PDF document or feel free to contact us.*

Japan is one of the top 10 countries in the world with frequent earthquakes. The 2020 White Paper on Land, Infrastructure, Transport and Tourism has also reported an increase in the probability of major earthquakes occurring. Regarding the Nankai Trough earthquake, the probability of an earthquake with a magnitude of 8 to 9 occurring within the next 30 years is estimated to be 70 to 80%. At Hotron, we recommend the introduction of seismic devices for earthquake countermeasures in buildings and equipment. The seismic device 'HK-2' is a product that automatically performs various controls that have been pre-set when it detects strong shaking equivalent to a seismic intensity of 5 lower or higher. For example, it can automatically execute actions such as: "Open automatic doors and gates to secure evacuation routes and access for emergency vehicles" "Transmit signals to the control room and stop facility equipment" "Unlock the keys to locked lockers" "Automatically play voice guidance" For more details, please download the materials or contact us.

The "Hotron Non-Contact Switch" allows you to open and close doors without directly touching door knobs or switches, making it hygienic! You can choose from two types: the "Hand Wave Sensor," which only requires you to wave your hand, and the "Foot Switch," which only requires you to place your foot at the entrance. It reduces the risk of virus and bacterial infections in places where hygiene is a concern, such as food factories, restaurants, hospitals, and nursing facilities. 【Features】 ○ Reduces the risk of virus infection by allowing door operation without contact ○ A wide variety of options to choose from based on application and location ○ Ideal for places where hygiene is a priority, such as food factories and medical facilities ○ Prevents unnecessary detection due to the switch mechanism 【Product Lineup】 ■ Hand Wave Sensor Series ○ Exposed waterproof type, front, down, and side-facing types "PF-R5" ○ Exposed type, front-facing type "PF-R1" ○ Embedded type, front-facing type "PF-U2" ○ Exposed type, downward wide type "PF-R4" ■ Foot Switch Series ○ Slim type with wide opening, vertical beam type "PF-01S" ○ Slim type with wide opening, horizontal beam type "PF-03S" ○ Standard type, horizontal beam type "PF-05" ◎ For more details, please download the catalog or contact us.
