Vinyl ester resins offer increased strength corrosion resistance and durability and are used in a wide variety of applications. Vinyl esters also use peroxides e g. Derakane momentum 411 350 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.

It is a solution of methyl ethyl ketone peroxides and cumyl hydroperoxide in phlegmatizer. Mekp is the catalyst hardener needed to cure polyester and vinyl ester resins. Essentially they comprise a base of polyester resin strengthened with epoxy molecules in the backbone of the molecular chain. Applications crystic ve 679 03pa was developed for use as a infusion resin with a wide range of gel times with various catalysts.
