Description

VESTALITE® S 102 is a curing agent for epoxy resin matrix designed for SMC applications. Systems using VESTALITE® S 102 have a low initial viscosity during compounding, allowing excellent fiber wetting, high fiber volume fraction and efficient processing. The high reactivity of the hardener allows fast curing in about 3 min at 150 °C.
