Description

PN-3M is a single part phthalonitrile resin with higher glass transition temperature and outstanding thermal stability, specially developed for vacuum infusion and RTM technologies. Pre-curing at 180°C allows to remove parts from tool after cooling. Post-curing provides glass transition temperature above 450°C. Moreover, PN-3M does not support combustion. Can be used for high temperature tooling up to 450°C.
