Advances in fire retardant materials 2008.
Epoxy novolac vinyl ester. The matter of choice for composite structures where material has exposure to aggressive chemicals. Is a one component moisture cured. Zero 0 voc epoxy. While they have high mechanical strength values similar to epoxy resins they are easy to apply similar to unsaturated polyester resins.
They offer high resistance to solvents acids and oxidizing substances such as chlorine. They also offer high retention of strength and toughness at elevated temperatures. They are produced by the addition of α β unsaturated carboxylic acids to epoxy 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.
The two main types of epoxy resins are bisphenol a diglycidyl ether dgeba and epoxy phenol novolac epn. It is a highly chemical resistant resin that provides excellent resistance to alkalis acids solvents and a broad range of chemicals. The diester product is then dissolved in a reactive solvent such as styrene to approximately 35 45 percent content by weight. Novolac vinyl ester resins afford excellent corrosion resistance high structural properties and.
Epoxy vinyl ester resins ver are an important class of high performance thermoset molding resins. Due to its high molecular weight and low permeability it will withstand exposure to a broad range of acids caustics and solvents. High temperature vinyl ester.
