Vinyl Ester Resin
Manufacturer & Supplier
Leading vinyl ester resin manufacturer and supplier offering premium vinylester resin, vinyl ester fiberglass resin, and vinyl ester laminating resin. Superior corrosion resistance, high temperature performance, and exceptional mechanical properties for chemical processing, marine, and industrial applications.
What is Vinyl Ester Resin?
Vinyl ester resin (also known as vinylester resin or VE resin) is a high-performance thermoset vinyl ester polymer that bridges the gap between polyester and epoxy resins.
Unlike standard polyester resins, vinyl ester resins have ester groups only at the ends of the molecular chain, resulting in superior chemical resistance, better mechanical properties, and lower water absorption. This makes them ideal for vinyl ester fiberglass composites in harsh environments.

Vinyl Ester Resin FAQ
What is vinyl ester resin?
Vinyl ester resin (also called vinylester resin) is a high-performance thermoset polymer combining the processing advantages of polyester with the corrosion resistance of epoxy. It's widely used in vinyl ester fiberglass composites for chemical processing, marine, and industrial applications.
What is the vinyl ester resin cure time?
Vinyl ester resin cure time varies by formulation and temperature. At 25°C with standard MEKP catalyst, gel time is typically 10-20 minutes, with full cure achieved in 24-48 hours. Heat post-cure (60-80°C) can accelerate the process. Need specific cure profiles for your production line? Contact our engineers for custom catalyst recommendations.
What is the vinyl ester resin price?
Vinyl ester resin price typically ranges higher than polyester but lower than epoxy. As a direct factory, Lechi allows you to bypass trading companies, saving 20-30% on premium Bisphenol-A and Novolac grades. Contact us for a factory-direct quote.
Where can I get vinyl ester resin data sheet and MSDS?
We provide comprehensive vinyl ester resin data sheets and MSDS (Material Safety Data Sheets) for all our products, including LC-9001S and LC-9007. Documentation includes physical properties, chemical resistance charts, and safety info. Download directly from product pages or request via email.
Can vinyl ester resin be used for pipes and coatings?
Yes! Vinyl ester resin is excellent for manufacturing vinyl ester pipe (FRP piping systems) and heavy-duty anti-corrosion coatings. Its superior chemical resistance makes it the industry standard for acid/alkali environments.
What is the vinyl ester resin temperature range?
Vinyl ester resin temperature range depends on the grade. Standard Bisphenol-A vinyl ester (LC-9001S) has a heat deflection temperature (HDT) of 100-120°C, suitable for most corrosion-resistant applications. Novolac vinyl ester (LC-9007) offers superior heat resistance with HDT above 210°C, ideal for high-temperature chemical processing equipment and industrial applications. For continuous service temperature, subtract 20-30°C from HDT values.
Is your vinyl ester resin SVHC free?
Yes, all our vinyl ester resins are SVHC (Substances of Very High Concern) free and fully REACH compliant. We use only REACH-registered raw materials and can provide complete compliance documentation including SVHC declarations and Safety Data Sheets for your regulatory requirements. This makes our vinyl ester resin suitable for export to the EU market.
