Vinyl Ester Resin Heat Resistance

They offer high resistance to solvents acids and oxidizing substances such as chlorine.

Vinyl ester resin heat resistance.

Vinyl ester resins offer in general excellent resistance to acids alkalis hypochlorites and many solvents. Tooling resin system 297 50. Vinyl ester resins are produced by the reaction esterification between an epoxy resin and an unsaturated monocarboxylic acid. Novolac vinyl ester resins afford excellent corrosion resistance high structural properties and outstanding laminate capabilities at ambient and high temperatures.

Essentially they comprise a base of polyester resin strengthened with epoxy molecules in the backbone of the molecular chain. Vinyl esters also use peroxides e g. 197p hetron corrosion heat resistant polyester resin 87 60 365 60. It s heat resistant and blended for durability.

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. Derakane 470 series resinsare epoxy novolac based vinyl ester resins designed to provide exceptional thermal and chemical resistance properties. These resins comprise our premium offerings in infrastructure building and repair as well as corrosion resistance. Can be used when organic chemicals such as benzyl chloride chlorobenzene phenol and divinyl benzene are present.

303 clear polyester casting resin 19 50 195 00. High density cross linked products are suitable for temperatures above 250 of 121 oc. 301 polyester laminating resin 17 95 131 95. A novolac modified epoxy vinyl ester resin with excellent corrosion resistance to about 121ºc 250ºf.

Vinyl ester is formulated for maximum corrosion resistance to most fuels vapors and chemicals. Standard epoxy vinyl ester resins are limited to 220 250 of 104 121 oc in most applications.
