Epoxy Vinyl Ester Resin Chemical Resistance
It is common to increase the strength of epoxy with fibrous reinforcement or mineral fillers.
Epoxy vinyl ester resin chemical resistance. Polives 721 epoxy novolac based vinyl ester resins are. Vinyl ester resins offer in general excellent resistance to acids alkalis hypochlorites and many solvents. Polives 721 epoxy novolac based vinyl ester resins are designed to provide exceptional thermal and chemical resistance. Their unique combination of high hdt and elongation makes them resins of choice for applications with thermal cycling e g for chemical reaction vessels.
Their unique combination of high hdt and elongation makes them resins of choice for applications with thermal cycling e g for chemical reaction vessels. It offers improved thermodynamic resistance over polyester alongside a broader range of resistance to aggressive corrosives. They are based on bisphenol a epoxy resin and they provide resistance to a wide range of acids alkalis bleaches and solvents for use in many chemical processing applications. It offers high resistance from solvents acids and oxidizing substances including chlorine.
Are low styrene monomer bisphenol a epoxy vinyl ester resins with mechanical thermal and chemical resistance properties between derakane 411 and derakane 470 resins. Reactivity vinyl ester resin that offers a high degree of chemical resistance and toughness. References and notes in some cases conventional solvents such as xylenes are also used. They offer excellent toughness and fatigue resistance.
Epoxies can be converted to vinyl ester resin through esterification with acidic catalysts creating an intermediate product with mechanical strengths lower than that of epoxy resins but greater than polyester. It is a resin used when both chemical resistance and flame retardancy are required. Epoxy vinyl ester resins also find uses in coatings particulalry for the marine building and construction industries due to their excellent corrosion and weathering resistance. It s high retention of strength and toughness at higher temperatures makes it ideal for flue gas applications.
Standard epoxy vinyl ester resins are limited to 220 250 of 104 121 oc in most applications. Derakane and derakane momentum 411 resinsare the globally recognized standard for epoxy vinyl ester resins. Are low styrene monomer bisphenol a epoxy vinyl ester resins with mechanical thermal and chemical resistance properties between derakane 411 and derakane 470 resins. Epoxy resin have an excellent electrical thermal and chemical resistance.
