What Alink does

Alink Co., Ltd. (주식회사 알링크) is a South Korean deep-tech company founded in 2015 by researchers from the Korea Institute of Materials Research, commercializing the world's first aluminum wet coating technology. The company applies its proprietary aluminum precursor ink and continuous coating process to deposit conductive aluminum nano-structures on fabric, plastic textile, thread, and paper substrates, achieving greater than 90% solvent recovery in a Busan Techno Park mass production facility.

Alink's commercial portfolio spans three product lines built on this platform: (1) Air CleSan air purifying modules for HVAC systems, ventilation filter boxes, air purifiers, and heat exchangers that combine mechanical and electrostatic filtration to deliver MERV13/MERV14 ratings, over 90% PM0.3 removal, 99.9% antibacterial and 99.5% antiviral effectiveness, and approximately 70% blower power savings; (2) aluminum-coated conductive fabric and filter media for wearable electronics, skin-attaching healthcare devices, and EMI shielding applications; and (3) environment-energy powder materials, including high-purity nano-sized aluminum nitride (99.9%) for thermal interface materials and lithium chloride recovered as a byproduct for all-solid-state battery solid electrolytes. Alink holds 19+ registered domestic patents plus additional pending applications and 5+ international patents, with ISO9001, ISO14001, Korean Green Technology, and RoHS certifications.

Alink generates revenue via direct B2B enterprise sales and through a strategic distribution partnership with S&I Corp, Korea's leading high-rise building management firm, targeting multi-use facilities such as offices, hospitals, hotels, shopping malls, and public buildings. Named enterprise customers include YG Entertainment, LG Twin Tower, Busan International Finance Center, Gangnam Oakwood Hotel, subway stations, and Changwon Hanmaeum Hospital, supplemented by an IoT-enabled managed air quality service. To date, the company has raised approximately $4.17M USD across a 2017 TIPS-linked round, a 2020 Series-A, and a 2022 bridge investment, and currently operates exclusively within the South Korean market.
