Audited Supplier REL 411 Epoxy Vinyl Ester Resin
REL 411 epoxy vinyl ester resin is based on bisphenol-A epoxy resin and provides resistance to a wide range of acids, alkalis, bleaches, and organic compounds for use in many chemical processing industry applications.REL vinyl ester resins are a new generation of resins that can be used to improve fabrication efficiency and product quality.Their lighter color makes defects easier to see and correct while the resin is still workable. The resin's improved reactivity properties often permit an increase in the lay-up thickness per session. The longer stability provides additional flexibility to fabricators in storage and handling.
