大日精化工業 List of Products and Services

This is an insulating thermal grease/gap filler that uses in-house manufactured materials such as urethane resin and composite oxide-based thermal fillers. Tailored for low thermal resistance, it employs resin synthesis and dispersion processing technologies developed over many years, resulting in a thermally conductive resin paste that combines low hardness and high adhesion, taking advantage of urethane properties. Since it does not contain low molecular siloxane, there are no concerns about contact failures due to outgassing inside electronic components. Additionally, the thermal filler uses our own soft-type filler, which reduces wear inside the dispenser and contributes to lower running costs of the equipment. By in-house manufacturing the resin and filler, we have also achieved a reduction in the overall product cost.

• Parts and Materials

Replacing the traditional crustacean-derived chitosan, we use chitosan isolated from "mushrooms," achieving a high "natural origin index" and "antibacterial properties," while also possessing "moisturizing" and "film-forming" abilities. The improvement in the biomass content of cosmetics contributes to a natural image.

This is an ink for PFAS-free reverse printing lamination. It uses a urethane resin called "HPU (hydroxy polyurethane)" as the main binder, which incorporates 10% CO2 in its chemical structure. By utilizing plant-derived components and using CO2 as a raw material, it becomes a carbon recycling ink that contributes to the realization of a carbon-neutral society.

MF Color is an inorganic pigment dispersion designed for water-based product coloring. With an extremely low content of dispersants, it excels in compatibility and minimizes the impact of coloring agents on the film properties and weather resistance. Despite being primarily composed of inorganic materials and high pigment content, it does not form hard cakes and is relatively low in viscosity, making it easy to handle. - For more details, we look forward to your catalog download and inquiries. We also accept consultations for dispersion designs tailored to various requests.

• Photocatalysts and various wall materials (exterior and interior walls, etc.)

This is a water-based paint color base that disperses organic and inorganic pigments, with a VOC content of less than 0.1% (1,000 ppm).

• Exterior coating materials

The Dipyroxide #7300 series is an alumina-based composite oxide powder (thermal conductive filler) developed by applying our synthetic technology for composite oxide pigments. By combining alumina with a small amount of several metal oxides, it has a higher thermal conductivity compared to alumina. Additionally, its rounded shape and low hardness reduce wear on molds, molding machines, pumps, and blades or drills used during the processing of molded products, contributing to longer equipment lifespan and prevention of contamination.

We offer PFAS-free water-based flexo inks and water-based gravure inks. 【About Water-Based Flexo Inks】 The complete water-based formulation of inks, which is a challenging issue in gravure printing, is achievable in flexo printing. Considering the global environment, working conditions, and production costs, water-based flexo printing is used in some plastic films in Europe and the United States as the best printing method. Additionally, due to recent advancements in surrounding technologies such as the introduction of CTP and the fine line technology of anilox rolls, flexo printing has become a new generation printing method that can achieve high-quality image quality comparable to gravure printing. Dai Nippon Ink & Chemicals will contribute to the further development of the flexo printing market in Japan by offering high-quality water-based flexo inks.
