Use of epoxy phenol novolacs including Bisphenol-F can greatly enhance the performance of corrosion resistant coatings and high temperature composites. In selecting resins for these applications, it is important to understand the influence of functionality, advancement and their relationship on viscosity and EEW in formulating systems. Failure to do so can result in selecting a resin that will fail because it is inadequately cured or exhibits a viscosity that is too high. Proper selection of the resin and matching the correct curing agent stoichiometry will guarantee optimal performance.
