Vinyl ester (VE)

Alternative and trade names
Atlac®, Epovia®


It is a vinyl ester resin (Bisphenol-A epoxy based/Styrene-free/Brominated/Urethane modified) with excellent resistance against many chemicals at elevated temperatures. It brings great strength & toughness. It can be used in combination with a broad variety of fibers, including glass and carbon fibers
