安達新産業 Company Profile

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.

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.

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.
