The Momentive product "TSA750" is an oil compound type silicone defoamer that combines solid active ingredients based on silicone oil. Due to the unique low surface tension of silicone and the interfacial destabilization effect from compounding, it rapidly penetrates and disperses into the foam film, inducing localized rupture of the foam film (promoting film drainage). As a result, both the initial defoaming ability and defoaming efficiency are significantly improved compared to pure silicone oil. Additionally, this product complies with the "silicone resin" standards of the Food Sanitation Act and is designed as a process additive that can be used in food processing. ■Features ■Applications ■Positioning of TSA750 For more details, please check our website.

A technology that simultaneously imparts conductivity and near-infrared optical properties to rigid resin optical components. In recent years, with the proliferation of automotive LiDAR and various infrared sensors, the demand for optical components that achieve both high transmittance and low reflectance in the 905nm band has rapidly increased. Especially in sensing using ToF methods or pulsed lasers, even slight reflection losses or scattering directly affect detection accuracy, making wavelength-specific optical design essential. On the other hand, the cover materials that protect these sensors from external environments require specific characteristics of resin materials, such as mechanical strength, impact resistance, dimensional stability against temperature changes, processability, and suitability for mass production, making the coexistence of optical and mechanical properties a significant design challenge. At Adachi New Industries, we have established a composite thin-film process that combines the acrylic resin material "Alonix Sheet" from Toa Gosei Co., Ltd. with the following.

Momentive's "TSA732" is an emulsion-type silicone defoamer with a 25% active ingredient content, made by emulsifying silicone oil compounds. It can be used as an industrial defoamer for water-based foaming liquids and demonstrates excellent persistence. In the field of water-based paints and inks, fine bubbles can cause appearance defects and reduce production efficiency. With the rise of high-speed lines and environmentally friendly formulations, there are increasing cases where traditional defoamers are insufficient. In particular, achieving both "compatibility and persistence" is one of the challenges faced by many formulators. In response to these issues, TSA732, leveraging Momentive's silicone technology, becomes an effective option. For more details, please check our company website.

The evolution of food tech goes beyond mere efficiency and automation. Alternative proteins, cultured meat, smart agriculture, food waste reduction, personalized nutrition design—what supports the forefront of these advancements is sensing technology that visualizes "invisible information." At the core of this is "light." Optical thin films are key components that read the state of food and raw materials non-contact, quickly, and with high precision by selectively transmitting, reflecting, or blocking specific wavelengths. We, Adachi New Industry Co., Ltd., propose co-creation with the food tech sector as a partner that selects, controls, and designs light, including environmental resistance. 1. Entering an era of "seeing" food quality through wavelengths 2. Advancements in "foreign substance inspection" and optical thin films 3. Co-creation with food tech companies! 4. Technical support from the conceptual stage Adachi New Industry Co., Ltd. integrates spectral design, film formation technology, and environmental durability evaluation, accompanying you from the conceptual stage to mass production implementation as a co-creation partner that supports food safety, quality, and experiential value. Shall we create next-generation food tech products together, starting from the design of light? For more details, please check our company website.

In recent years, technological innovations in the agricultural sector have significantly shifted from traditional biological approaches such as soil improvement and breeding to an engineering concept of "designing the environment itself." Particularly noteworthy is smart agriculture, which integrates precise control of light environments with sensing technology. Plant growth is complexly determined not only by light intensity but also by wavelength distribution, angle of incidence, temporal variations, and interactions with surrounding temperatures. In other words, agriculture can essentially be described as "the science of spectral control." In this context, optical thin films and optical filters play an extremely important role. Optical thin films are functional materials that allow for precise design of reflectivity, transmittance, absorbance, and interference characteristics through control of film thickness on the nanometer scale. By using multilayer interference structures, it is possible to selectively transmit and reflect specific wavelengths, which directly contributes to optimizing effective light for photosynthesis in plants and controlling unwanted infrared and ultraviolet light.

In industrial processes, "foam" is not just a cosmetic issue. It is an invisible trouble factor that directly affects quality, productivity, and equipment stability. For example, the following problems can occur on-site: - Tank overflow: Foam expands above the liquid level, causing loss of the contents and contamination of surrounding equipment. - Pump cavitation: The inclusion of air bubbles reduces pump performance, leading to vibrations, noise, and equipment damage. - Coating unevenness and appearance defects: The presence of foam in coating or painting processes can result in pinholes and craters. - Sensor malfunction: Liquid level sensors and optical sensors detect foam and produce incorrect control signals. - Filter clogging: Foam and fine bubbles accumulate in filters, leading to increased pressure loss and more frequent replacements. These are not isolated troubles; they can lead to larger issues such as reduced yield, equipment downtime, and quality complaints. For more details, please check our company website.

In the medical and healthcare fields, light has already become an indispensable infrastructure. From endoscopes, fluorescence observation devices, blood analyzers, pulse oximeters, and wearable vital sensors to regenerative medicine and phototherapy devices, optical control technologies such as "wavelength selection," "reflection control," "stray light suppression," and "high-sensitivity detection" are required in every scenario. However, in actual design settings, it cannot be said that there are many cases where equipment manufacturers and optical thin film manufacturers engage in sufficient discussions from the early stages. As a result, filters and mirrors are often "added later" in the optical system's post-processing, leaving room for improvements in S/N ratio, miniaturization, and low power consumption that should have originally been achieved. We will redefine the role of optical thin films in the medical and healthcare fields and explore the possibilities from the perspective of "functional co-creation" rather than just "material supply." 1. The essence of wavelength design in biosensing 2. How reflection and absorption control change the image quality of endoscopes and observation systems 3. Wearable medical devices and angle-dependent design 4. High-durability thin films in phototherapy and sterilization fields The option of co-creation - a proposal from Adachi New Industry Co., Ltd.

The food industry is currently undergoing a significant technological transformation. Traditional food manufacturing has relied heavily on the experience and operational know-how of craftsmen. However, in recent years, amidst new trends such as plant-based foods, precision fermentation, high-protein functional beverages, continuous production processes, and the smart factory movement, food manufacturing is evolving into a more precise process control industry. Within this change, issues that have previously been overlooked are becoming apparent. One of these issues is the presence of foam. Foam is not merely an aesthetic problem; in next-generation food factories, it can become a hindrance to process control. ◆ New challenges of foam in plant-based foods ◆ Foam stabilization in high-protein beverages ◆ The issue of foam in smart factories ◆ The defoaming solutions that Adachi New Industry Co., Ltd. aims for For more details, please check our company website.

Sports are constantly evolving. The lightweighting of equipment, the high-strength of materials, form optimization through data analysis, and the high functionality of apparel—technological innovations for improving competitive performance are now spreading not only among top athletes but also across all sporting environments. In recent years, advancements in sensor technology and AI analysis have significantly shifted sports from "sensation" to "science." However, what underpins this transformation is, in fact, "light." Visibility, tracking, sensing, and presentation—all these aspects utilize light information, and it is optical thin film technology that influences their accuracy and comfort. Now, this "technology that controls light" is poised to unlock new possibilities in sports. It is not just a simple coating; it is an advanced spectral design technology that selects wavelengths, controls reflection, and blocks unwanted light. This technology enhances athletes' decision-making abilities, improves sensor accuracy, and serves as a foundational technology for optimizing the competitive environment itself. ◆ Enhancing athlete performance × Optical thin films ◆ Data sports × Optical filters ◆ Integration with biosensing ◆ Towards future sports devices For more details, please check our company website.

The foam generated during the food manufacturing process is not merely a collection of air. It exists as a "structure" stabilized by naturally derived components originally present in the food, such as proteins, polysaccharides, lipids, and surfactants. Therefore, the foam that occurs during food processing does not necessarily disappear naturally over time; rather, it is often maintained or even amplified by processes such as stirring, heating, and circulation. What becomes important here is the approach to defoaming. In food manufacturing settings, it is common to consider the addition of defoaming agents or changes to the product only after foam manifests as issues like filling defects or reduced productivity. However, in reality, much of the amount and stability of foam, as well as its residual behavior, are determined more by the processing conditions than by the defoaming agents used. In other words, defoaming should not be seen as a supplementary measure to be addressed in later stages, but rather as an element that should be incorporated from the design stage of the manufacturing process. ◆ The properties of foam vary significantly by process ◆ Defoaming design considered by industry-specific processes ◆ The design flexibility of silicone defoaming agents ◆ The defoaming approach provided by Adachi New Industry Co., Ltd.

In the development of coating materials for semiconductors and functional chemicals, the evaluation of resistance to electromigration and ion migration has become an unavoidable and important theme. On the other hand, migration is not a phenomenon that can be simply determined by material properties alone. The differences in insulating films, protective films, and coating materials interact with wiring materials and current conditions in ways such as hygroscopicity, ion residue, barrier properties, dielectric characteristics, film thickness, film density, and interfacial adhesion, ultimately manifesting as wiring degradation or insulation breakdown. However, in actual evaluation settings: ◆ The wiring structure and material conditions differ with each evaluation. ◆ The effects of materials and structural factors cannot be separated. ◆ Reproducibility and comparability of evaluation results are difficult to achieve.

Merchandise for fans has evolved primarily through the combination of "design" and "materials." The beauty of illustrations, printing techniques, and the choice of materials such as acrylic, metal, and fabric have significantly enhanced the appeal of these products. However, the impression we get when we see merchandise is not solely influenced by design and materials. The feelings we experience, such as "beautiful," "eye-catching," or "photogenic," are greatly affected by how light reflects, transmits, and disperses. For example, have you ever had the experience of seeing the room's lighting reflected when displaying an acrylic stand? Or when taking a photo with your smartphone, noticing a flare (a whitish blur) on your favorite character's face, or seeing colors that look different from their true hues? This is not necessarily due to poor design or printing, but rather because the behavior of light has not been adequately controlled. ◆ Merchandise for fans is moving to the next phase of evolution ◆ Merchandise for fans can be transformed significantly with "light" ◆ Proposal: Merchandise for fans that "selects only the favorite" using bandpass filters ◆ Co-creation proposal: Shall we shape the next standard with Adachi New Industry?

Momentive's "TIG830SP" is a thermally conductive silicone oil compound. Compared to conventional oil compounds, it has less oil separation, contributing to high reliability. It also exhibits excellent thermal conductivity over a wide temperature range. *What is a thermally conductive silicone oil compound?* It is a grease-like composite material that is highly filled with thermally conductive fillers (typically metal oxides) based on silicone oil, used to enhance the heat dissipation efficiency of electronic components and heating elements. It is ideal for thermal design of electronic components that require both heat dissipation and insulation. Proper application amount and film thickness management are crucial for thermally conductive silicone oil compounds; too much will be extruded, while too little will increase thermal resistance. The application surface must be degreased to prevent poor adhesion. Caution is needed around optical components and contact areas due to the possibility of oil bleeding and volatility at high temperatures. Since it does not cure, it can easily shift due to vibration, making measures against misalignment, such as using frames or pads, effective. Additionally, it may swell some resins and rubbers, so prior evaluation is essential. For more details, please check our website.

Electrochemical analysis chips are devices that utilize electrical signals such as voltage and current to read chemical reactions. The chip is equipped with working electrodes, counter electrodes, and reference electrodes, allowing for the highly sensitive detection of redox reactions occurring in solution. In recent years, compact devices combining microfluidic technology and MEMS technology have become widespread, rapidly expanding their use in medical POCT (Point of Care Testing), environmental monitoring, food testing, and life sciences. In these applications, there is a demand for higher sensitivity, miniaturization, multiplexing, and speed of detection, and essential to achieving this are the miniaturization of electrode structures and the formation of high-quality metal thin films, namely thin film metallization technology. ◆ Key to electrochemical analysis: The quality of data is determined by the performance of the electrodes ◆ Thus, "thin film metallization" is necessary ◆ Technical points when performing thin film metallization ◆ Examples of performance improvements brought by thin film metallization ◆ Future trends: Demand accelerating with POCT and wearables ◆ The inseparable relationship between electrochemical analysis chips and thin film technology For more details, please check our company website.

Despite using the same thermal conductive silicone, - Evaluation results are unstable - It performed well in prototypes, but there is performance variation in mass production Such troubles are actually not uncommon. Many of the causes are due to storage and handling conditions rather than "material quality." Thermal conductive silicone is not just a "bonding and coating material," but a functional material precisely designed to meet design specifications. In other words, it is a material that only exhibits catalog performance when used correctly. ■ Thermal Conductive Silicone is a "Functional Material" Thermal conductive silicone is not just a paste-like material; it is a high-performance material designed as a composite material. Its performance is established not by a single component but by a precise balance of multiple elements. The main components are as follows.

Modern advanced technology relies on precisely manipulating parameters such as the wavelength, direction, and intensity of light. At the center of this light control is the optical mirror. The basic function of an optical mirror is to reflect incident light in a specific direction with high efficiency, but it goes beyond being just a reflective surface. Depending on the application, advanced optical performance is required, such as "which wavelengths to reflect or transmit," "how much reflectivity to achieve," and "how accurately to focus and form images." - The role and importance of optical mirrors - The two main types of mirrors: metallic mirrors and dielectric mirrors - Metallic mirrors: basics and characteristics of reflection - Dielectric mirrors: technologies that achieve high reflectivity - Comparison table: contrast between metallic mirrors and dielectric mirrors - Specific examples of differentiation based on applications - Summary and outlook: the importance of technology selection and contributions to industry For more details, please visit our company website.

Optical filters are important devices used to extract only the necessary wavelengths from light or to block unnecessary wavelengths. They are utilized in a wide range of fields, from cameras and displays that we commonly see, to spectroscopic analysis devices used in medical and bio fields, as well as in industrial applications such as laser processing and optical communication. Light encompasses a broad wavelength range, including ultraviolet, visible, and infrared light; if the desired light cannot be precisely controlled, it can lead to issues such as false detection, increased noise, and decreased image quality. This is where the concepts of "cut-on" and "cut-off" come into play. These concepts indicate the boundary where light begins to transmit and the boundary where transmission ends, forming the foundation of optical filter design. 1. Definition and Basic Principles of Cut-On and Cut-Off The most important parameters for correctly designing and evaluating optical filters are the "cut-on wavelength" and "cut-off wavelength." These are not just names; they are reference values that numerically define the effective performance of the filter, specifically which wavelength ranges are transmitted and which ranges are blocked. 2. Technical Points of Design and Control For more details, please visit our company website.

Momentive's "TIA0330" is a non-corrosive, fast-drying, heat-dissipating one-component room temperature curing silicone adhesive with reduced low molecular siloxanes. It reacts with moisture (water) in the air to cure into a rubber-like elastomer that excels in heat resistance, cold resistance, electrical insulation, weather resistance, and water resistance. It requires no mixing or heating, significantly simplifying the process from application to curing. Its semi-fluidity makes it suitable for automatic dispensing and it has excellent conformability to complex shapes. It is ideal for a wide range of electronic devices where heat dissipation is critical, such as automotive ECUs, inverters, communication base stations, and servers/PCs. At Adachi New Industries, we provide consistent technical support from material selection based on application to optimization of application conditions and prototype follow-up. If you have concerns regarding heat dissipation design or adhesive challenges, please feel free to consult us. *About the corrosion mechanism of general silicones Corrosion of copper-based metals by silicone occurs when moisture-curing silicones react with water vapor in the air, releasing by-products such as acetic acid and alcohol. When these components come into contact with the copper surface, they undergo a chemical reaction, forming copper oxide and corrosive compounds. Corrosion accelerates, especially in energized environments or high humidity, leading to poor conductivity and contact degradation.

Momentive's "TIA235R" is a two-component addition-type liquid silicone rubber designed for heat dissipation and insulation sealing of electrical and electronic components. By mixing component (A) and component (B) in a 1:1 ratio and curing at room temperature or with heat, it hardens into a rubber-like material and adheres to various substrates. After curing, it exhibits excellent heat resistance, cold resistance, and weather resistance, demonstrating stable heat dissipation and electrical insulation properties over a wide temperature range.

When considering heat-dissipating silicone, the first thing that often draws attention is the value of "thermal conductivity (W/m·K)." While thermal conductivity is indeed an important indicator, in actual implementation environments, there are not a few cases where "even if the thermal conductivity on the catalog is high, the temperature does not decrease in the actual device." The reason for this is that heat dissipation performance is determined not by the physical properties of a single material, but by a combination of multiple factors such as: - Contact conditions - Compression conditions - Coating thickness - Interface conditions - Aging changes Therefore, understanding that "high thermal conductivity does not equal the optimal solution" is the starting point for selecting heat-dissipating materials.

The UV-IR cut filter is an optical thin-film filter that selectively removes unwanted light in the ultraviolet (UV) and infrared (IR) wavelength ranges, allowing only specific wavelength bands of light to be transmitted or reflected with high precision. This filter achieves wavelength selectivity by utilizing interference effects through the precise layering of multilayer dielectric films and metal films. Generally, it requires control of film thickness on the order of nanometers, exceeding several tens to over a hundred layers, and its optical properties are determined by multiple parameters such as film thickness accuracy, refractive index of the film material, smoothness of the film interfaces, and adhesion of the films. 1) What is a UV-IR cut filter? 2) Historical background of UV-IR filter manufacturing in Japan 3) Why has overseas manufacturing of UV-IR cut filters progressed? 4) If UV-IR cut filters were to be produced again in Japan... necessary points (hypothesis) 5) Technically important points when selecting UV-IR cut filters 6) Future prospects Conclusion - The efforts of Adachi New Industry Co., Ltd. to focus on domestic production in Japan For more details, please visit our company website.

As the high integration, miniaturization, and high output of semiconductor devices rapidly advance, "thermal management" has become one of the most critical parameters that directly affects product reliability, lifespan, and safety, rather than being a secondary design issue. With the miniaturization of transistors, current density has been increasing year by year, and in the power device sector, the widespread adoption of SiC and GaN has led to higher allowable operating temperatures, while heat generation density (W/cm²) has certainly risen. As a result, issues such as increased junction temperature, the emergence of hotspots, and stress concentration due to temperature gradients have become more serious problems than ever before. For example: - Power modules in EVs and charging infrastructure - High-heat chips in AI accelerators and GPUs - High-density mounted boards in automotive ECUs - LED modules with increasing brightness - Industrial power supplies and inverters Despite being in different fields, they all share the commonality that we have entered an era where "thermal design determines the performance limits of products." This is not just about lowering temperatures... For more details, please refer to AD-Chemi.
