Abstract

We carried out comparative study of the effect of inhibitor-loaded nanocontainers on corrosion protection performance of polyepoxy powder coatings employing neutral salt-spray test (5% NaCl, 35 °C, different time). We demonstrated that halloysites and mesoporous silica particles loaded with corrosion inhibitor 8-hydroxyquinoline can be homogeneously distributed in powder coating effectively reducing corrosion of the metal substrate over 1000 h of salt-spray test. Addition of only 2 wt.% of inhibitor encapsulated in both nanocontainers to the powder coating is sufficient to decrease the delamination effect by 2–3 times and suppress the formation of the pitting corrosion.
