Vinyl Ester Or Epoxy

This condensation product acts as a crosslinking agent and to improve adhesion to glass fibers.

Vinyl ester or epoxy.

It adds excellent strength rigidity adhesion water and chemical resistance. These resins form durable laminates and coatings. Vinyl ester resins are typically formulated from styrene and a condensation product of methacrylic acid with an epoxy. Essentially they comprise a base of polyester resin strengthened with epoxy molecules in the backbone of the molecular chain.

Cloth and polyester resin. Vinyl ester can be used for concrete and steel tank linings or as a concrete floor topping. The curing process is radical initiated. Epoxies polyesters and vinylesters represent two resin families.

Jimslade sep 7 2005 3 joined. Epoxy adheres to wood much better than polyester does. Vinyl is similar to polyester. The vinyl groups refer to these ester substituents which are prone to polymerize.

Polyester is small chain carbon whereas vinylester is long chain carbon which makes it more flexible. Epoxy vinyl ester resins ver are an important class of high performance thermoset molding resins. Vinyl ester resins are a cross between polyester resins and epoxy resins. Epoxy s base is amine which is a different family altogether.

Epoxies belong to a family of resins which are epoxy functional which means they can be cured with amine curing agents at room temperatures to form excellent adhesives and composite resins. These coatings typically exceed both polyester and epoxy in corrosion resistance temperature resistance and elongation toughness. You can put epoxy over polyester but not the other way. Vinyl ester resins are produced by the reaction esterification between an epoxy resin and an unsaturated monocarboxylic acid.

Vinylester is essentially a styrene modified epoxy resin. Resins are bisphenol a diglycidyl ether dgeba and epoxy phenol novolac epn. Regarding costs vinyl ester resin is more expensive than polyester resin but cheaper than epoxy resin. They are produced by the addition of α β unsaturated carboxylic acids to epoxy resins.

Vinyl ester resin or often just vinyl ester is a resin produced by the esterification of an epoxy resin with acrylic or methacrylic acids. Vinyl esters also use peroxides e g.
