Abstract (en)

[origin: WO2021032537A1] A fast cure cycle for thermocurable resins coupled with long storage stability is achieved by applying a curative containing particulate cure initiator to the surface of a layer of the thermocurable resin and by employing conditions of temperature and pressure to drive the curative into the resin to cause rapid cure of the resin.
