Epoxy vinyl ester resin structure.

Ve resins are a combination of both polyester resin and epoxy resins best properties. As the length of the chain is available to absorb impact loads this makes vinyl ester resins more durable and resilient than polyesters. While they have high mechanical strength values similar to epoxy resins they are easy to apply similar to unsaturated polyester resins. Epoxy vinyl ester resins ver are an important class of high performance thermoset molding resins.

Essentially they comprise a base of polyester resin strengthened with epoxy molecules in the backbone of the molecular chain. The two main types of epoxy resins are bisphenol a diglycidyl ether dgeba and epoxy phenol novolac epn. Vinyl ester resins are produced by the reaction esterification between an epoxy resin and an unsaturated monocarboxylic acid. The vinyl groups refer to these ester substituents which are prone to polymerize.

Vinyl esters also use peroxides e g. Vinyl ester ve resins are thermosetting polymers that combine the good chemical mechanical and thermal properties of epoxy resins with the rapid cure of unsaturated polyester resins ve resins have high chemical and hydrolytic resistances good toughness a high modulus and good thermal and electrical insulation properties. Bisphenol a based epoxy vinyl ester resins provide high chemical resistance and mechanical strength. Vinyl ester resin or often just vinyl ester is a resin produced by the esterification of an epoxy resin with acrylic or methacrylic acids.
