Epoxy Vinyl Ester

However most are prepared solely with reactive vinly type monmomers.

Epoxy vinyl ester.

Ve resins are a combination of both polyester resin and epoxy resins best properties. It adds excellent strength rigidity adhesion water and chemical resistance. 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. Vinylester is essentially a styrene modified epoxy resin.

Bisphenol a based epoxy vinyl ester resins. The diester product is then dissolved in a reactive solvent such as styrene to approximately 35 45 percent content by weight. 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. Epoxy adheres to wood much better than polyester does.

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. It is water resistant. The vinyl groups refer to these ester substituents which are prone to polymerize.

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. 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. 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. A new generation of epoxy vinyl ester resins. Cloth and polyester resin.

Vinyl esters also use peroxides e g. Regarding costs vinyl ester resin is more expensive than polyester resin but cheaper than epoxy resin. To cover wood a laminate using epoxy resin and 10 oz cloth will yield a much better job than 10 oz.
