Novolac Vinyl Ester Resin

It exhibits a corrosion resistance similar to derakane 470 resins in most environments.

Novolac vinyl ester resin. Resins are bisphenol a diglycidyl ether dgeba and epoxy phenol novolac epn. Interplastic s novolac epoxy based vinyl ester resin. The matter of choice for composite structures where material has exposure to aggressive chemicals. Derakane 510n resin is brominated epoxy novolac vinyl ester resin that offers a moderate degree of fire retardance1.

2 2 7 vinyl esters vinyl ester resins are typically formulated from styrene and a condensation product of methacrylic acid with an epoxy. These resins form durable laminates and coatings. Vinyl ester resins offer increased strength corrosion resistance and durability and are used in a wide variety of applications. This condensation product acts as a crosslinking agent and to improve adhesion to glass fibers.

The vipel f085 series is ideally suited for applications where outstanding mechanical properties and resistance to chemicals oxidation and heat are required. Epoxy vinyl ester resins ver are an important class of high performance thermoset molding 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. These resins comprise our premium offerings in infrastructure building and repair as well as corrosion resistance.

They are produced by the addition of α β unsaturated carboxylic acids to epoxy resins. The vinyl groups refer to these ester substituents which are prone to polymerize. More fatigue resistant than standard epoxy vinyl ester resins. Novolac vinyl ester ceilcote 222gf flakeline is a novolac vinyl ester resin system with graphite fillers which exhibits excellent resistance to both aliphatic and aromatic organic and inorganic acids including hydrofluoric acid.

The curing process is radical initiated. Extremely capable in chlor alkalai exposure or in paper processing chlorination processes resulting in wide use in tanks washer covers pipes valves ducting etc for the paper processing industry. It is also useful in hot wet fluegas environments where. 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.

While they have high mechanical strength values similar to epoxy resins they are easy to apply similar to unsaturated polyester resins. Novolac vinyl ester resins afford excellent corrosion resistance high structural properties and outstanding laminate capabilities at ambient and high temperatures.
