Greetings from the President
Since its establishment in 1947, AGC Seimi Chemical Co., Ltd. has, as a member of the AGC Group, consistently devoted itself to fine chemical research and development, creating a succession of technologies and products with distinct features, whether they be inorganic or organic.
We currently produce a variety of niche products including surface modifiers (surfactants etc.), various additives and polishing materials, which serve as key materials in the production processes of a wide range of fields including electronics, optics, energy and biotechnology.
Recent trends have seen technology’s core shift from hardware to software in the form of IT, IoT and AI. Completing the shift requires high-efficiency IC chips and various sensors, and the ever-higher grades of material technology needed to support these are now very much in demand. We aim to help meet such demand by continuing to focus on fine chemical research and development, providing functional materials with that little bit of extra novelty value compared to those of other companies. The synthesis and process technologies we consequently develop can then be effectively utilized to handle a full range of contracts from development to manufacturing. It is through such a course of action, and in line with our company creed of “Creation and Progress,” that we aim to constantly contribute to developing both our industry and society at large.
We look forward to receiving yet more of your helpful guidance and valued custom in future.

Origin of Company Name
With the arrival of the science of chemistry at the end of Japan's Edo period, the word 'chemie' (meaning 'chemistry' in Dutch) was given the Japanese pronunciation 'sha-mi.' 'Sha-mi' was then altered to 'sei-mi,' which sounded more appropriate in Japanese for a manufacturer of flavor, and Seimi Chemicals was born, retaining the name to this day.
