Benzoxazine resins can help you solve your toughest challenges

Our newest benzoxazines combine excellent stiffness and high-temperature performance with the ability to withstand exposure to moisture, chemicals and other corrosive materials. They’re ideal for use in extreme environments and offer low flammability. In addition, several of these systems are designed to cure out of autoclave.
Today’s generation of benzoxazine resins are also safer and easier to handle and process - they are storage stable at room temperature, release approximately 20% less energy1 during cure and do not generate volatiles2 during cure. In addition, Huntsman has formulated compatible diluents and accelerators that reduce viscosities as well as cure temperature and cycle times.

Benzoxazine Applications
Aerospace: primary and secondary structures as well as interior panels, bulkheads, galleys, lavatories and tray tables.
Transportation: automotive under-the-hood components as well as frames, body panels and structural reinforcements
for trucks, buses and light rail cars.
Oil/Gas: composite pipes, risers, down-hole plugs and high-pressure vessels.
Out-of-autoclave tooling: prepregs and infusion resins for high-performance, elevated-temperature tooling.
Electronic: halogen-free laminates for printed circuit boards.
