Resonac - About Us

In 2023, Resonac America, Inc., a wholly owned subsidiary of Resonac Corporation, Tokyo, Japan, was established after the integration of Showa Denko K.K. (SDK) and Showa Denko Materials Co., Ltd. (SDMC). “Resonac” was created as a combination of two English words, the word “resonate” and “c” as the first letter of “chemistry.” The new company name implies our strong commitment to firmly linking all of these for greater “resonation” toward a shared future and finding new partners as this resonance broadens, thereby creating a powerful movement to change society.

Resonac America, Inc.’s purpose, “Change society through the power of chemistry,” represents our desire to be the global top-level competence as a chemical manufacturer, to think beyond the conventional boundaries of our business activities, and to co-create a better society with stakeholders and communities. Through all its many changes, Resonac America, Inc., maintains a certain set of core values which include taking pride and passion in our work (Passionate & Results-Driven), showing mutual trust and respect (Open Minds & Open Connections), learning through trial-and-error (Agile & Flexible), and truly recognizing the power and potential of chemistry (Solid Vision & Solid Integrity).
