How large is China's sec-butyl acetate capacity and who actually produces it?
China's effective sec-butyl acetate capacity sits around 430,000 tons per year, with several long-idled units excluded. Only five plants remain active, and utilization has run at roughly 30-50% under power-rationing constraints, with some units down for extended upstream maintenance. No new capacity has been announced in recent years. Demand is structurally pressured: sec-butyl acetate is mainly an oil-based paint solvent, and the national push toward water-based coatings keeps eroding that outlet, while toluene and xylene continue to cap any price rebound.
