Epoxy Vinyl Ester

Advances in fire retardant materials 2008.

Epoxy vinyl ester. It adds excellent strength rigidity adhesion water and chemical resistance. Essentially they comprise a base of polyester resin strengthened with epoxy molecules in the backbone of the molecular chain. The hardener catalyst for vinyl ester resin and polyester resins is mekp. In some cases conventional solvents such as xylenes are also used.

Aoc vipel f010 series is a bisphenol a epoxy based vinyl ester resin dissolved in styrene. 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. Epoxy vinyl ester resins also find uses in coatings particulalry for the marine building and construction industries due to their excellent corrosion and weathering resistance. It is water resistant.

Bisphenol a based epoxy vinyl ester resins. Cloth and polyester resin. Vinyl ester resin or often just vinyl ester is a resin produced by the esterification of an epoxy resin with acrylic or methacrylic acids. However most are prepared solely with reactive vinly type monmomers.

Vinyl ester resins are the binary resin systems containing a dimethacrylate monomer from which the cured material gains most of its properties and a reactive monomer such as styrene which acts as a reactive diluent and also takes part in the cross linking reaction. Epoxy resin is an ideal resin for high performance and light weight parts. Regarding costs vinyl ester resin is more expensive than polyester resin but cheaper than epoxy resin. The vinyl groups refer to these ester substituents which are prone to polymerize.

Vinylester is essentially a styrene modified epoxy resin. Vinyl esters also use peroxides e g. While they have high mechanical strength values similar to epoxy resins they are easy to apply similar to unsaturated polyester resins. 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. The diester product is then dissolved in a reactive solvent such as styrene to approximately 35 45 percent content by weight. Epoxy adheres to wood much better than polyester does.
