Trixene BI 7960

Aliphatic blocked HDI biuret isocyanate. Acts as a crosslinking agent for hydroxyl-functional resins (polyester, urethane, acrylic etc). Its chemical structure offers a range of flexibility, functionality and branching for the compounder. Has DMP as the blocking agent, better color stability and lower unblocking temperature or shortened dwell time which reduces energy requirements. Also has resistance to yellowing, particularly on over bake and UV exposure. Trixene BI 7960 form coatings with improved resistance to chemical and environmental attack. It is typically formulated into 1-K coatings that are dried and cured under factory stoving conditions, e.g. for OEM metal components used in the automotive as well as consumer goods industries. Used for solvent-based coatings and coil as well as electrodeposition applications.
