Vinyl Ester Resins
Epoxy Strength. Polyester Versatility.
For extreme corrosion and thermal resistance, our vinyl ester resins combine epoxy-level performance with the processing ease of polyesters, the top choice for critical industrial and marine applications.
The Pinnacle of Corrosion Resistance
Vinyl ester resins are engineered by reacting epoxy resins with methacrylic acid, resulting in a backbone that combines the toughness and chemical resistance of epoxies with the processing advantages of polyesters.
They outperform orthophthalic, isophthalic, and Bis-A polyesters in corrosion resistance, toughness, and long-term durability, making them indispensable in highly corrosive, high-temperature, and structural applications.
Happy Composites supplies ISO 9001:2015 certified vinyl ester resins across the U.S., ensuring compliance, reliability, and technical support for your most demanding projects.
