大同化成工業 Product Lineup

We would like to introduce a highly dispersed and highly soluble hydrophilic polymer developed by our company, focusing on the challenges of "agglomeration" and "long dissolution time" associated with hydrophilic polymers.

• Cosmetic materials and raw materials

In recent years, as interest in reducing environmental impact has grown, the development of materials utilizing biomass raw materials has gained attention. The "biomass organic blue pigment" we are introducing this time is a blue pigment made from the glutamic acid-derived dye "indigoidine." Our company is working on improving alkali resistance and dispersion through our unique surface treatment technology, aiming for expansion into various applications.

• Organic Natural Materials

With our unique surface treatment technology, achieve a deeper blue-black than conventional products! The key to the color lies in the "surface" of the particles. Our newly developed carbon black surface treatment technology creates a deep black with an unprecedented blue tone. This technology enables high-quality color expression across a wide range of fields, including inks, paints, resins, and coatings. When the appearance of black changes, the impression of the product changes. We invite you to experience the difference!

In the ink industry, vibrant color development and high transparency are required. Particularly in printing inks and inkjet inks, color reproduction and ink stability are crucial. Improper use of pigments can lead to poor color development and ink issues. Our organic pigments (soluble azo pigments) are vivid, highly transparent, and ideal for coloring agents in inks. 【Application Scenes】 - Printing inks (offset inks, gravure inks, and various other inks) - Inkjet inks - Writing instruments 【Effects of Implementation】 - Vivid color development - High transparency - Improved stability of ink properties

Our trading department mainly handles UV photoinitiators. The main photoinitiator in UV systems provides the final product with the characteristic of quick drying, and environmentally, it generates low VOC emissions, enabling the production of energy-efficient and clean products. Additionally, by promoting the sale of UV photoinitiators and contributing to the spread of UV curing inks, we are helping to reduce environmental impact through energy conservation, decrease greenhouse gas emissions, and improve labor conditions by reducing VOCs. [Applications] ■ UV inks ■ UV coatings ■ Resists, etc. *For more details, please download the PDF or feel free to contact us.
