Vinyl Ester Resin Chemical Resistance

Fiberglass reinforced polymer frp or simply fiberglass is a composite product comprising a high strength material matrix.

Vinyl ester resin chemical resistance.

Derakane 510n resin is a brominated epoxy novolac vinyl ester resin that offers a high degree of fire retardance. Tough textiles reinforced with silicate fibers are bound with a liquid polymer such as vinyl ester resin which imparts stiffness to the fabric while impregnating the component with distinct corrosion thermal and abrasion resistance properties. It exhibits a corrosion resistance similar to derakane 470 resins in most environments. These resins feature an ester functional group r co 2 r with an unsaturated hydrocarbon side chain such as a c c double bond.

Vinyl ester resins are produced by the reaction esterification between an epoxy resin and an unsaturated monocarboxylic acid. References and notes in some cases conventional solvents such as xylenes are also used. Derakane 8084 resin is an elastomer modified bisphenol a epoxy vinyl ester resin that offers very high toughness impact and. While vinyl ester resins are classified as polyester based formulations they are actually an intermediate between a polyester backbone and epoxy terminations on the ends of the molecules.

Essentially they comprise a base of polyester resin strengthened with epoxy molecules in the backbone of the molecular chain. Vinyl ester or vinylester is a resin produced by the esterification of epoxy resin with unsaturated monocarboxylic acid. Derakane 510n resin is brominated epoxy novolac vinyl ester resin that offers a high degree of fire retardance1. Fatigue resistant than standard epoxy vinyl ester resins.

Vinyl ester resin is selected due to its well known performance in marine conditions and good chemical resistance to a wide range of chemicals including sour crude up to 100 c. Vinyl ester resin chemical resistance is the ability of vinyl ester resins to deter chemical attack under normal or elevated temperatures. They are very resistant to chemical attack by chlorine and bleach environments. It has a measured glass transition temperature t g of 110 c hence allowing the clamp to withstand up to a maximum service temperature of 80 c.

Vinyl esters have enhanced mechanical properties compared to polyesters with physical strength better impact and thermal shock resistance. It is also useful in hot wet flue gas environments where. Their bromine content makes them tougher and more fatigue resistant than standard epoxy vinyl ester resins. 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.

The combination of those properties yield stronger materials than polyesters and provide improved resistance to thermal. Vinyl esters also use peroxides e g.
