Vinyl Ester Resin Heat Resistance

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

Vinyl ester resin heat resistance.

It s low viscosity so it s easy to pour and just right for vacuum infusion. Derakane 470 series resinsare epoxy novolac based vinyl ester resins designed to provide exceptional thermal and chemical resistance properties. A novolac modified epoxy vinyl ester resin with excellent corrosion resistance to about 121ºc 250ºf. It s heat resistant and blended for durability.

Tooling resin system 297 50. 197p hetron corrosion heat resistant polyester resin 87 60 365 60. 301 polyester laminating resin 17 95 131 95. Vinyl ester resins offer in general excellent resistance to acids alkalis hypochlorites and many solvents.

Vinyl ester resins are produced by the reaction esterification between an epoxy resin and an unsaturated monocarboxylic acid. It features excellent impact strength and high tensile elongation. 303 clear polyester casting resin 19 50 195 00. Vinyl esters also use peroxides e g.

Standard epoxy vinyl ester resins are limited to 220 250 of 104 121 oc in most applications. Heat resistant vinyl ester resins for composite applications continued corrosion resistance since nves are often selected for their corro sion resistant properties several screening tests were performed with ranging polarity in cluding acid base organic solvent and water were performed. Novolac vinyl ester resins afford excellent corrosion resistance high structural properties and outstanding laminate capabilities at ambient and high temperatures. Vinyl ester is formulated for maximum corrosion resistance to most fuels vapors and chemicals.

Essentially they comprise a base of polyester resin strengthened with epoxy molecules in the backbone of the molecular chain. High density cross linked products are suitable for temperatures above 250 of 121 oc.
