Vinyl Ester Resin Uses

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 ester resin uses.

Their longer double bonded vinyl groups that link the ester groups together contribute a flexible nature to the resin. It is typically used in boat hulls gas tanks kayaks canoes and other items that will be exposed to chemicals such as fuel or water for extended periods of time. Vinyl ester resins are produced by the reaction esterification between an epoxy resin and an unsaturated monocarboxylic acid. Vinyl ester resins are a cross between polyester resins and epoxy resins.

To cover wood a laminate using epoxy resin and 10 oz cloth will yield a much better job than 10 oz. Because of this vinyl esters are generally used when high durability thermal stability and extremely high corrosion resistance are a. Vinyl ester resin or often just vinyl ester is a resin produced by the esterification of an epoxy resin with acrylic or methacrylic acids. Vinylester is essentially a styrene modified epoxy resin.

Vinyl ester resin is also more resistant to solvents and water degradation. Essentially they comprise a base of polyester resin strengthened with epoxy molecules in the backbone of the molecular chain. Cloth and polyester resin. Proper thickening with the usual thickening agents is an essential resin characteristic if the smc is to be ready to mold i e.

In some cases conventional solvents such as xylenes are also used. Polyester and vinyl ester resins are the most commonly used matrix resins to create composite parts. Vinyl ester resins vinyl esters are halfway between polyesters and epoxies as far as typical properties and toughness and they are a step up on a cost basis. The vinyl groups refer to these ester substituents which are prone to polymerize.

Vinyl esters also use peroxides e g. The diester product is then dissolved in a reactive solvent such as styrene to approximately 35 45 percent content by weight. Vinyl ester resins offer increased strength corrosion resistance and durability and are used in a wide variety of applications. These coatings typically exceed both polyester and epoxy in corrosion resistance temperature resistance and elongation toughness.

It adds excellent strength rigidity adhesion water and chemical resistance. Epoxy adheres to wood much better than polyester does. Vinyl ester can be used as a final coat after polyester resin to create a better water barrier. However most are prepared solely with reactive vinly type monmomers.

Mature in a reasonable time and to remain moldable long enough that it can be all used up under normal production schedules.
