Corrosion protection coatings are generally employed for protection of the steel structures that are exposed to different aggressive environments. This research evaluated the use of biobased ion exchangers as a sustainable means of improving corrosion protection coatings.</p> <p>Two base polymer coatings (vinyl and coal-tar epoxy) were considered.  The following types and dosages of biobased ion exchangers were evaluated in these coatings: (i) strong-base ion exchange cellulose in OH, PO<sub>4</sub>, SiO<sub>3</sub>, BO<sub>3</sub>, NO<sub>2</sub>, SO<sub>4</sub> and NO<sub>3</sub> forms at 1% by weight of resin; (ii) weak-acid starch citrate ion exchanger in H form at 1 wt.%; and (iii) strong-base ion exchange cellulose in OH form at 2 wt.%. In addition, a strong-base ion exchange resin in OH form was considered at 1 and 2 wt.% as control.  Different coating formulations were evaluated based on the outcomes of salt-fog corrosion, moisture resistance, pull-off strength, and abrasion resistance tests. The introduction of certain biobased ion exchangers in protective coatings was found to be an effective means of achieving improved levels of corrosion resistance, adhesion capacity, moisture stability and abrasion resistance.</p>}, number={1}, journal={Stavební obzor - Civil Engineering Journal}, author={Soroushian, Parviz and Balachandra, Anagi and Weerasiri, Rankothge and Darsanasiri, Nalin and Abdol, Nastran}, year={2022}, month={Apr.}, pages={1–15} }
