Showa Denko Materials

Showa Denko Materials (昭和電工マテリアルズ株式会社) was the name adopted in 2020 by Hitachi Chemical after it became a consolidated subsidiary of Showa Denko. Its corporate lineage traces back to Hitachi, Ltd., where research into oil-based varnish began in 1912, and to Hitachi Chemical's later product lines such as copper-clad laminates for printed wiring boards, photosensitive films, and lithium-ion battery anode materials. In 2023 Showa Denko and Showa Denko Materials were integrated to form Resonac Holdings and Resonac.

The corporate lineage of Showa Denko Materials traces to Hitachi, Ltd., where research into oil-based varnish began in 1912, which the company treats as its founding. Hitachi Chemical Industry, Ltd. was established in 1962, and in 1963 it took over the chemical products division of Hitachi, Ltd. and absorbed Hitachi Kako. Over the following decades it began manufacturing copper-clad laminates for printed wiring boards (1955), alkali-developable photosensitive film FOTEC (1978), circuit-connecting film ANISOLM for displays (1984), epoxy resin encapsulants (1992), and lithium-ion battery anode materials and CMP slurry for STI (1998). The company changed its trade name to Hitachi Chemical Co., Ltd. in 2013. In 2020 it became a consolidated subsidiary of Showa Denko and changed its name to Showa Denko Materials Co., Ltd. In 2023 Showa Denko and Showa Denko Materials were integrated to form Resonac Holdings and Resonac.
