Novolac vinyl ester market to grow at 6 cagr till 2025 more information https bit ly 2dd5ehs marine applications are estimated to contribute a share close to 20 in global vinyl ester market by 2025. The polyester resin is strengthened by the addition of epoxy resin.

Vinyl ester resins are a type or subset of polyester resin. Vinyl ester prepolymers are formed by reaction of epoxy resin polyol with acrylic or methacrylic acid which contains the vinyl group. Uses ceilcote 2 hardener. The best peroxide for standard vinyl ester application trigonox 239 cumene hydroperoxide promoter high reactive low peak exotherm in thick layers a must for vinyl ester gelcoats at room t only suitable in vinyl ester resins the best peroxide in case no gassing is allowed trigonox k 90 cumene hydroperoxide low reactive.

The marine industry involves product usage as gel coats barrier coats etc. These resins are resistant to chemical and thermal aggressive environments and prevent water absorption as well it prevents corrosion. 2 curing unsaturated polyester and vinylester resins with organic peroxides accelerators and other additives introduction this technical bulletin deals with the use of organic peroxides for curing of unsaturated polyester resins and.
