The results of exposing Fiber Reinforced Plastics (FRP) coupons made from
three different types of corrosion resistant thermosetting resins in several dilute water
soluble/miscible organic compounds for up to one year are presented. In addition, the
results of a study with four resins in contact with a two-phase aqueous/organic system
are discussed. The purpose of these studies was to determine the limits of acceptable
performance of FRP based on a range of epoxy vinyl ester resins in solvent containing
environments.
