Novolac Vinyl Ester Resin

More fatigue resistant than standard epoxy vinyl ester resins.

Novolac vinyl ester resin.

Vinyl ester resin or often just vinyl ester is a resin produced by the esterification of an epoxy resin with acrylic or methacrylic acids. Ve resins are a combination of both polyester resin and epoxy resins best properties. 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.

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. These resins comprise our premium offerings in infrastructure building and repair as well as corrosion resistance. 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. Uses ceilcote 2 hardener.

They are very versatile in the wide range of capabilities they. Novolac vinyl ester resins. It exhibits a corrosion resistance similar to derakane 470 resins in most environments. 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. Derakane momentum resins are a new generation of resins that can be used to improve fabrication efficiency and. 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.

The diester product is then dissolved in a reactive solvent such as styrene to approximately 35 45 percent content by weight. Vinyl ester is formulated for maximum corrosion resistance to most fuels vapors and chemicals. The two main types of epoxy resins are bisphenol a diglycidyl ether dgeba and epoxy phenol novolac epn. Epoxy vinyl ester resins ver are an important class of high performance thermoset molding resins.

The matter of choice for composite structures where material has exposure to aggressive chemicals. They are based on either bisphenol a or novolac chemistry with methacrylic acid forming the polymer. It is also useful in hot wet fluegas environments where. It s heat resistant and blended for durability.
