Epoxy Vinyl Ester Resin
However most are prepared solely with reactive vinly type monmomers.
Epoxy vinyl ester resin. Epoxy adheres to wood much better than polyester does. Regarding costs vinyl ester resin is more expensive than polyester resin but cheaper than epoxy resin. It is important to note that of the three vinyl ester resin will provide the highest corrosion resistance temperature resistance and elongation toughness. While they have high mechanical strength values similar to epoxy resins they are easy to apply similar to unsaturated polyester resins.
The chemistry of epoxies and the range of commercially. Vinylester is essentially a styrene modified epoxy resin. Ve resin is a tougher resin because of its longer molecular chains. It adds excellent strength rigidity adhesion water and chemical resistance.
Ve resins are a combination of both polyester resin and epoxy resins best properties. Cloth and polyester resin. Vinyl esters also use peroxides e g. 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. Essentially they comprise a base of polyester resin strengthened with epoxy molecules in the backbone of the molecular chain. Advances in fire retardant materials 2008. The applications for epoxy based materials are extensive and include coatings adhesives and composite materials such as those using carbon fiber and fiberglass reinforcements although polyester vinyl ester and other thermosetting resins are also used for glass reinforced plastic.
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. Bisphenol a based epoxy vinyl ester resins provide high chemical resistance and mechanical strength. A new generation of epoxy vinyl ester resins. 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.
The hardener catalyst for vinyl ester resin and polyester. The vinyl groups refer to these ester substituents which are prone to polymerize. It can withstand repeated bending better than both polyester and epoxy resin. The diester product is then dissolved in a reactive solvent such as styrene to approximately 35 45 percent content by weight.
To cover wood a laminate using epoxy resin and 10 oz cloth will yield a much better job than 10 oz. Vinyl ester resin is considered a hybrid of polyester and epoxy meaning its handling characteristics properties and price generally fall just between the other two.
