ABSTRACT
Vinyl esters have a wide range of corrosion resistance, particularly to strong corrosive acids, bases, and salt solutions, up to temperatures of 200°F (93°C). These are produced from the reaction of epoxy resins with ethylene-unsaturated carboxylic acids. The epoxy resin backbone imparts toughness and superior tensile elongation properties. The vinyl ester generally used for chemical process piping systems is derived from a diglycidyl ether of bisphenol-A epoxy resin with the addition of methacrylate end groups to provide maximum corrosion resis tance.
