Epoxy Ester Oligomer

Features

This is our new promotion – Partial esterification resins based on the reaction between partial oxirane ring of epoxy resin and AA or MAA. They have oxirane ring and acryloyl group together, thus UV and Heat cure available respectively. Applicable for dual cure and delayed cure capitalized its cure difference. Excellent shelf life with stable low viscosity under 60 degree. Custom Made and Lab products.
