Effects of hydrotalcite intercalated with corrosion inhibitor on cathodic disbonding of epoxy coatings

Corrosion protection of carbon steel by solvent free epoxy coating containing hydrotalcites intercalated with different organic corrosion inhibitors

“…The adhesion strengths of epoxy coating containing HT-BTSA or HT-BZ are very close and higher than the one of pure epoxy coating. A similar result was obtained for the solvent based epoxy coatings [38]. The increase of the adhesion properties after incorporation of organically modified hydrotalcites can be explained by the presence of OH group on the nanoreservoirs, this group having a high affinity for the native oxide layer formed on the metallic substrate in short contact with the atmosphere before application of the organic coating.…”

“…In our previous works, hydrotalcites modified by 2-benzothiazolythio-succinic acid inhibitor (HT-BTSA) were synthesized, incorporated in a solvent based epoxy coating and applied on carbon steel [36][37][38]. The obtained results proved that HT-BTSA improved corrosion protection, adhesion and resistance to cathodic disbonding of solvent based epoxy coatings.…”

Determination of Optimum Concentration of Benzimidazole Improving the Cathodic Disbonding Resistance of Epoxy Coating

“…In the case of inhibitor loaded nanocontainers, Izadi et al [24], for example, showed that release of Nettle molecules as green corrosion inhibitor and zinc cations from a nanocontainer, synthesized by l-b-l process with the core of Fe 3 O 4 nanoparticles, provide epoxy coating with a significant cathodic disbonding protection. Moreover, the positive effect of zinc aluminum hydrotalcite intercalated with benzothiazolylthio-succinic acid on the cathodic delamination resistance of epoxy coating was reported by Hang et al [30]. Interestingly, the influence of either direct or indirect addition of corrosion inhibitors to the conversion coatings or any pretreatments on the cathodic delamination of overlaying polymeric films has been studied in some literature [24,31,32].…”

Corrosion Inhibition of Carbon Steel by LDH/Go Hybrid Intercalated With 2-Benzothiazolythio-Succinic Acid

“…LDHs and graphene have lamellar structure and complementary properties, and hydrotalcite/graphene composites have been studied for application in different fields [14][15][16]. For organic coatings the combination of hydrotalcite and graphene has the synergistic effect on the fire retardation of materials [13,17]. In our previous works, layered double hydroxides intercalated with 2-benzothiazolylthio-succinic acid (BTSA) as a container of corrosion inhibitor was studied for corrosion protection of carbon steel [18][19][20].…”
