EPIKOTE™ Resin 03121




Product Description

EPIKOTETM Resin 03121 is a low viscosity epoxy resin based on a blend of a bisphenol F resin (produced from bisphenol F and epichlorohydrin) and a bisphenol A resin (produced from bisphenol A and epichlorohydrin), and containing an added proportion of a modification agent.


The resin has a low volatility and is nearly inodorous, factors which are responsible for its agreeable handling characteristics.
