Technical FAQ
Q: What is the difference between Epoxy Vinyl Ester and Polyester Resin?
Vinyl ester resin is a hybrid of polyester resin and epoxy resin. It combines the mechanical toughness and chemical resistance of epoxy with the faster curing and ease of use of polyester. It offers significantly better corrosion resistance, hydrolytic stability, and physical strength than standard orthophthalic or isophthalic polyester resins.
Q: When should I choose Novolac Vinyl Ester over Bisphenol-A Vinyl Ester?
Choose Novolac Vinyl Ester when your application involves higher operating temperatures (above 120°C) or exposure to aggressive solvents and oxidizing acids where standard Bisphenol-A based resins might degrade. It has a higher cross-link density for extreme durability.
Q: Can your vinyl ester resin be used for filament winding and pultrusion?
Yes, we offer specific viscosity grades of vinyl ester resin tailored for different fabrication processes including filament winding, pultrusion, hand lay-up, and spray-up. We can adjust the reactivity and viscosity to match your production line requirements.
Q: Is vinyl ester resin suitable for marine barrier coats?
Absolutely. Vinyl ester is the industry standard for marine barrier coats (skin coats) because its dense molecular structure is highly impermeable to water, effectively preventing osmotic blistering (boat pox) in fiberglass hulls.
