What MNTech does

MNTech Co., Ltd. (미래나노텍) is a South Korea-headquartered nano-component materials manufacturer founded August 1, 2002 and publicly listed on the Korea Exchange (KRX ticker 095500). The company is the global No. 1 in LCD TV optical film market share and exports over USD 200 million annually from optical films alone. It operates six core product lines: optical films and plates (including prism sheets, multiple sheets, AIOP, quantum-dot sheets, polarization compensation films); EMI filters for noise reduction and electromagnetic shielding; secondary battery materials (cathode additives and high-purity 99% lithium hydroxide for high-nickel EV cathodes) produced through subsidiary Mirae Advanced Materials; automotive and building window films (IR/dyed and safety); retroreflective films (automotive license plates, road traffic signs, vehicle conspicuity) produced through subsidiary MNTech Global; and multi-coating films (privacy films and hidden display films).

The underlying technology platform centers on ultra-precision coating, precision patterning (including photo-lithography and soft-mold processes), roll-to-roll imprinting, polymer formulation, and nano-coating. MNTech has 171 domestic and 88 overseas patent applications (157 and 68 registered respectively) covering optical sheets, retroreflective films, EMI shielding, touch panels, decorative films, and — most recently — dry-process solid electrolyte membranes for all-solid-state batteries developed jointly with Hanyang University. FY2025 consolidated revenue was KRW 538,533 million with operating profit of KRW 20,929 million and net profit of KRW 13,599 million.

MNTech serves display and electronics manufacturers (Samsung Electronics cited as a key customer), EV and battery manufacturers (a 45,000-ton anhydrous lithium hydroxide supply contract starting H1 2026), automotive OEMs and component makers, and construction/infrastructure customers. It uses a B2B direct-sales model through dedicated domestic and overseas sales teams plus subsidiary-specific sales channels. Manufacturing is located in Cheongju (HQ and R&D Center), Gumi (Mirae Advanced Materials lithium hydroxide plant, acquired from POSCO Future M in H1 2025), Egypt (MNTech Optics, since April 2022), and Canada (Mirae Advanced Materials subsidiary, construction begun 2024). CEO and founder Kim Cheol-young has led the company since 2002.
