NBDA/PRO-NBDA is a mixture of 2,5- and 2.6-disubstituents, that has four stereoisomers.
At ambient temperatures, NBDA/PRO-NBDA is low-viscosity liquid having no odor or a slight characteristic odor.
PRO-NBDA is available with competitive price.
Aromatic amines -methylene linkage-
These monomers are the raw materials of polyimide, polyamide, and a curing agent for epoxy resin. The resin made from these monomers is excellent in heat resistance and mechanical properties (Tg of the resin is higher than Tg of the resin made from aromatic ether diamines).
Aromatic amines -sulfone linkage-
These monomers are a curing agent for epoxy resin. The epoxy resin made from these monomers is excellent in heat resistance and flexibility. SO2 is better performance in bonding carbon-fibers.
Liquid aromatic amines
These monomers are the raw materials of special resins. And, these monomers are a liquid at room temperature, though these are aromatic amines. So, these are excellent in reactivity and handling. Furthermore, the resins made from these monomers are excellent in heat resistance and mechanical properties.
These monomers are key monomers in the production of epoxy resins and polycarbonate plastic. These monomers have excellent mechanical properties.
