Covestro AG(COV)
HQ DE
German specialty polymer and coating company (XETRA: 1COV), spun out of Bayer AG in 2015. Became the dominant global fiber optic coating supplier when it acquired DSM's Resins & Functional Materials business for €1.61B (announced Sep 2020, closed April 1, 2021) — absorbing DSM's 40-year legacy in optical fiber coatings. Then acquired JSR Corporation's 30% stake in Japan Fine Coatings Co., Ltd. (Tsukuba) in January 2022, becoming sole owner. Now self-states it "produces more than 50% of the world's optical fiber coatings." Brands: DeSolite® (primary/secondary UV-cure acrylate coatings), Cablelite® (ribbon matrix/inks), Bufferlite® (tight buffer). Key production sites: Elgin, Illinois USA (former DSM Desotech; main global volume plant); Tsukuba, Japan (Japan Fine Coatings, 100% owned, ~65 staff); Zwolle, Netherlands (coating resins). Also a leading polycarbonate and polyurethane supplier for automotive, electronics, and construction — fiber optic coatings are a small but strategically critical business unit.
