An innovative test program using Electrochemical Impedance Spectroscopy (EIS) was used to evaluate high build was compared and contrasted with a 100% volume solids polyamide epoxy, which was applied in linings for rapid water immersion for structures such as penstocks, pilings and clarifiers. The performance of a two-coat application of a low -temperature cure 80% volume solids modified phenalkamine epoxy (hereafter “phenalkamine epoxy”) was compared with a one-coat application of a 100% volume solids polyamide epoxy. Each system was immersed in distilled and deionized water after only a brief period of curing time (24 -48 hours). Case histories exemplify the benefits and use of the phenalkamine epoxy technology for rapid immersion service.
