Used as a trifunctional (B3) aromatic triamine cross-linker and curing agent for epoxy resins and other thermosets, imparting high cross-link density. Employed as a monomer for hyperbranched polyimides, polyamides and star polymers in high-performance, thermally stable network materials for aerospace, electronics, semiconductor packaging, adhesives and composites. Also used as a building block for hole-transport/triarylamine-type materials in organic electronics.
