Novolac Vinyl Ester Resin

Epoxy vinyl ester resins ver are an important class of high performance thermoset molding resins.

Novolac vinyl ester resin.

Novolac vinyl ester resins afford excellent corrosion resistance high structural properties and outstanding laminate capabilities at ambient and high temperatures. It exhibits a corrosion resistance similar to derakane 470 resins in most environments. Derakane momentum resins are a new generation of resins that can be used to improve fabrication efficiency and. They are based on either bisphenol a or novolac chemistry with methacrylic acid forming the polymer.

Derakane 510n resin is brominated epoxy novolac vinyl ester resin that offers a moderate degree of fire retardance1. More fatigue resistant than standard epoxy vinyl ester resins. Vinyl ester is formulated for maximum corrosion resistance to most fuels vapors and chemicals. The vinyl groups refer to these ester substituents which are prone to polymerize.

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. 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. Vinyl ester resin is considered to be a hybrid of polyester and epoxy resins meaning its handling characteristics properties and even price generally fall just between the two. Uses ceilcote 2 hardener.

Novolac vinyl ester resins. While they have high mechanical strength values similar to epoxy resins they are easy to apply similar to unsaturated polyester resins. They are very versatile in the wide range of capabilities they. Ve resins are a combination of both polyester resin and epoxy resins best properties.

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 matter of choice for composite structures where material has exposure to aggressive chemicals. Vinyl ester resin or often just vinyl ester is a resin produced by the esterification of an epoxy resin with acrylic or methacrylic acids. The two main types of epoxy resins are bisphenol a diglycidyl ether dgeba and epoxy phenol novolac epn.

The vipel f085 series is ideally suited for applications where outstanding mechanical properties and resistance to chemicals oxidation and heat are required. It is also useful in hot wet fluegas environments where. The diester product is then dissolved in a reactive solvent such as styrene to approximately 35 45 percent content by weight. They are produced by the addition of α β unsaturated carboxylic acids to epoxy resins.
