Mercapto functional azole compounds as organic corrosion inhibitors in a polyester-melamine coating

Electrochemical and optical microscopy study of red pepper seed oil corrosion inhibition by self-assembled monolayers (SAM) on 304 SS

“…In addition to serving as anodic passive layers, they can also increase a coating's adhesion properties. Moreover, the active region of the compound is also able to protect the metal from other influences due to the steric hindrance effect and polarity interactions [9][10][11]. Derivative compounds of azole, such as 2-mercaptobenzimidazole (MBI) and 2-mercaptobenzoxazole (MBO), have been used as organic corrosion inhibitors in polyestermelamine coatings.…”

“…Derivative compounds of azole, such as 2-mercaptobenzimidazole (MBI) and 2-mercaptobenzoxazole (MBO), have been used as organic corrosion inhibitors in polyestermelamine coatings. The azole derivative compounds in the coating mixtures lend corrosion inhibition to mild steel after spraying 1 M NaCl on the surface of the specimen [10].…”

Enhanced corrosion protection of mild steel by the synergetic effect of zinc aluminum polyphosphate and 2-mercaptobenzimidazole inhibitors incorporated in epoxy-polyamide coatings

“…Ce(NO 3 ) 3 [18]. In another research, Mahdavian and Ashhari added 2-mercaptobenzimidazole and 2-mercaptobenzoxazole to a polyestermelamine coating and observed a synergetic effect in corrosion protection of the coatings due to formation of protective layer on steel substrate [19]. Balaskas et al reported an improvement in the barrier properties of silicate-epoxy coatings doped with organic and inorganic inhibitors and applied on Al alloy 2024-T3.…”

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

“…For instance, addition of anticorrosion pigments [15][16][17], organic inhibitors, e.g., azole derivatives [18][19][20], thioglycolate esters, mercaptocarboxylic acids [21], organic sulfides, organic amines, organic phosphates, phenols [22] disodium oleamidesulfosucinate, lignosulfonic acid-doped polyanilin [23], and also inhibitor loaded nanocontainers [24] have been proposed to increase the coating resistance against the destroying phenomena. The electrolyte penetrating into the coating may transfer organic inhibitor molecules and inhibiting species liberated from pigment particles to the interface, where the materials make a complex passive layer on the metal surface, blocking the active regions and reducing the rate of electrochemical reactions [25][26][27][28][29]. 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.…”
