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. date: 2023 publisher: Oles Honchar Dnipro National University official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-85183612519&doi=10.15421%2fjchemtech.v31i4.290101&partnerID=40&md5=84113b944874b2c6c999ccdef5ce4768 id_number: 10.15421/jchemtech.v31i4.290101 full_text_status: none publication: Journal of Chemistry and Technologies volume: 31 number: 4 pagerange: 844-854 refereed: TRUE issn: 26632934 citation: Chowdhury, N.E. and Yusoff, P.S.M.B.M. and Mustapha, M.B. and Lah, N.F.B.C.
