Novolac Vinyl Ester

The diester product is then dissolved in a reactive solvent such as styrene to approximately 35 45 percent content by weight.

Novolac vinyl ester. Due to its high molecular weight and low permeability it will withstand exposure to a broad range of acids caustics and solvents. All substrates aluminium asbestos cement rendering. 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. The vinyl groups refer to these ester substituents which are prone to polymerize.

Prior to paint application all steel surfaces should be assessed and treated in accordance with iso 8504 2000. Novolac vinyl ester resins afford excellent corrosion resistance high structural properties and outstanding laminate capabilities at ambient and high temperatures. Ceilcote 222ht flakeline is a glass flake filled novolac vinyl ester coating which exhibits excellent resistance to both aliphatic and aromatic organic solvents and to concentrated organic and inorganic acids it offers outstanding chemical resistance with quick turn around for service and also high temperature resistance. They are very versatile in the wide range of capabilities they.

Novolac vinyl ester organotin free antifouling other phenolic epoxy polyester polysiloxane polyurethane pure epoxy silicone solvent free epoxy vinyl ester zinc epoxy zinc phosphate zinc silicate products by substrate. 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. Vinyl ester resins are a type or subset of polyester 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. Novolac vinyl ester all surfaces to be coated should be clean dry and free from contamination. Bisphenol a and novolac epoxies generally are used. Vinyl ester prepolymers are formed by reaction of epoxy resin polyol with acrylic or methacrylic acid which contains the vinyl group.

Novolac based vinyl esters are more reactive than bisphenol a and pro duce polymers with greater. While they have high mechanical strength values similar to epoxy resins they are easy to apply similar to unsaturated polyester resins. These resins comprise our premium offerings in infrastructure building and repair as well as corrosion resistance. Ceilcote 232 flakeline is a flake filled novolac vinyl ester coating which exhibits excellent resistance to both aliphatic and aromatic organic solvents and to concentrated organic and inorganic acids it offers outstanding chemical resistance with quick turn around for service and also high temperature resistance.
