Epoxy Vinyl Ester

Vinyl ester resins are produced by the reaction esterification between an epoxy resin and an unsaturated monocarboxylic acid.

Epoxy vinyl ester.

The vipel f010 series is ideally suited for use in hand lay up spray up filament winding smc and pultrusion processes where outstanding mechanical properties and excellent resistance to chemicals and heat are required. Regarding costs vinyl ester resin is more expensive than polyester resin but cheaper than epoxy resin. A new generation of epoxy vinyl ester resins. It adds excellent strength rigidity adhesion water and chemical resistance.

Advances in fire retardant materials 2008. The hardener catalyst for vinyl ester resin and polyester resins is mekp. Vinylester is essentially a styrene modified epoxy resin. 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 adheres to wood much better than polyester does. Essentially they comprise a base of polyester resin strengthened with epoxy molecules in the backbone of the molecular chain. 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. Vinyl esters also use peroxides e g.

Epoxy resin is an ideal resin for high performance and light weight parts. The vinyl groups refer to these ester substituents which are prone to polymerize. To cover wood a laminate using epoxy resin and 10 oz cloth will yield a much better job than 10 oz. Cloth and polyester resin.

Aoc vipel f010 series is a bisphenol a epoxy based vinyl ester resin dissolved in styrene. 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. Ve resins are a combination of both polyester resin and epoxy resins best properties.

The diester product is then dissolved in a reactive solvent such as styrene to approximately 35 45 percent content by weight. It is water resistant. In some cases conventional solvents such as xylenes are also used.
