description: Bisphenol A epichlorohydrin (BPA-EC) as a resin, and cycloaliphatic amine (CAA) as a curing agent, are conventionally used for formulating epoxy coatings for industrial applications. However, due to its noticeable toxicity, alternative curing agents such as aminopropyl triethoxysilane (APTES) can be used instead of CAA. Moreover, BPA-EC can be partially replaced by kraft lignin. In this study, the influences of APTES, BPA-EC, and kraft lignin on corrosion resistance were analyzed using the robust statistical analytical capabilities of the existing optimization models. Response surface methodology and the Box-Behnken design model were used to investigate the respective and cumulative effect of each element. Initially, the model has a P value of 0.0037, with some of the terms not significant. Thus, a modified model has been introduced keeping only the significant terms. Finally, a P-value of 0.0004 has been achieved. Although the model showed a non-linear association for all the constituent elements, no cumulative relation has been found. However, statistics showed that BPA-EC is a necessary element for the coating to be corrosion-resistive, as corrosion resistance of the coating is proportional to the quantity of BPA-EC in the coating. Thus, the study concludes that in an attempt to decrease toxicity from the proposed APTES-cured coating matrix, BPA-EC cannot be completely replaced by lignin. © 2023 Oles Honchar Dnipro National University.
