Vinyl Ester Gelcoat (White)

This white vinyl ester gelcoat combines the outstanding chemical resistance and hydrolytic stability of a bisphenol A vinyl ester resin base with high-quality titanium dioxide pigmentation for a brilliant white, durable cosmetic surface. It bridges the gap between standard isophthalic gelcoats and purely functional chemical-resistant versions, delivering both aesthetic surface quality and excellent chemical protection. The product is suitable for marine tanks, chemical containment structures, water treatment equipment, and industrial FRP panels where white color is desired but enhanced chemical resistance is required. Pre-accelerated with cobalt and dimethyl aniline for broad temperature cure capability. Catalysis with MEKP at 1–2% gives gel times of 22–40 minutes at 20°C. Barcol hardness after full cure is 45–53. Compared to white isophthalic gelcoat, the vinyl ester base provides substantially lower water absorption and better chemical permeation resistance, making it the preferred choice for tanks containing dilute acids, alkalis, or process chemicals. The thixotropic formulation supports both spray and brush application.
