An epoxy vinyl ester laminating resin system that provides resistance to a wide range of acids, alkalis, bleaches, and solvents. This resin holds up in corrosive environments. It is designed to withstand heavy design loads without causing failure due to resin damage. This system provides superior elongation and toughness for FRP equipment with better impact resistance and less cracking due to cyclic temperature, pressure fluctuation, and mechanical shocks providing a safety factor against damage during process upsets or during shipping installation. Manufactured by Ashland.
