"Since our establishment in 1970, we have, through the leveraging of our proprietary technology and know-how, witnessed extraordinary growth as a formulator of resin compounds and products tailored to meet the many and exacting demands of our loyal customers around the world.

As you can see on our company homepage, we are in the process of further expanding our lineup of products to include not only epoxy-type products (liquids and powders), but also a range of urethane and silicone-based insulating, coating, and conductive paste materials. Our products are currently used in everything from electronics to automobile parts, industrial machinery, sporting goods, and other items for daily-use. We deliver products to markets mainly in Japan, Europe, China, and Southeast Asia, but our reach is global. Thanks to your continued support and patronage, we now offer over 900 types of products to over 1,000 companies both inside and outside of Japan.

In 2003, we became an affiliated member of the Arakawa Chemical Industries, Ltd. Group, further strengthening our development capabilities and allowing us to proceed with the development of products which make full use of new materials and synthesis technologies. In 2007, we established a new head office, an R&D center, and a factory for the production of liquid-based products in Hadano City, Japan. In 2011, we began operations at a factory geared towards the production of conductive materials—replete with its own clean environments—and since then have been moving forward in the development of other production environments and facilities that can produce new types of products.

Moving forward, the company will strive to create new and innovative products that bring forth new forms of wealth creation to our customers. We will do this by quickly adapting to the ever-evolving needs and technological trends of the modern world, including those relating to environmental issues, the electrification of the automobile, and the automobile industry's increasing demand for ever lighter materials and parts."
