Wanhua WANNATE® CW-20 is a solvent-free, aliphatic polyisocyanate based on hexamethylene diisocyanate (HDI). It is primarily used as a curing agent for high-performance polyurethane coatings. Applications include automotive refinish paints, industrial anti-corrosion coatings, and clearcoats requiring excellent weather resistance, chemical stability, and mechanical durability. CW-20 is ideal for two-component systems due to its low viscosity, fast drying, and outstanding gloss retention. It is especially suited for exterior applications in harsh environments, such as marine, infrastructure, and aerospace coatings, where long-term durability and UV resistance are critical. Its low VOC profile also supports compliance with environmental regulations.
