Epoxy Vinyl Ester Resin Structure

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.

Epoxy vinyl ester resin structure.

Vinyl esters also use peroxides e g. These resins form durable laminates and. The two main types of epoxy resins are bisphenol a diglycidyl ether dgeba and epoxy phenol novolac epn. As the length of the chain is available to absorb impact loads this makes vinyl ester resins more durable and resilient than polyesters.

Essentially they comprise a base of polyester resin strengthened with epoxy molecules in the backbone of the molecular chain. Ve resins are a combination of both polyester resin and epoxy resins best properties. Vinyl ester resins are produced by the reaction esterification between an epoxy resin and an unsaturated monocarboxylic acid. Vinyl ester resin or often just vinyl ester is a resin produced by the esterification of an epoxy resin with acrylic or methacrylic acids.

Epoxy vinyl ester resins ver are an important class of high performance thermoset molding resins. They are produced by the addition of α β unsaturated carboxylic acids to epoxy resins. Bisphenol a based epoxy vinyl ester resins provide high chemical resistance and mechanical strength. The diester product is then dissolved in a reactive solvent such as styrene to approximately 35 45 percent content by weight.
