The anticorrosive behaviour of an epoxy coating modified with hydrophobic nano-silica on phosphated carbon steel was the subject of a new study.
According to the researchers, the anticorrosive performance of an epoxy coating is significantly improved when hydrophobic nano-silica is added to an epoxy matrix, adding hydrophobic nano-silica can effectively increase the diffusion path of water-soluble corrosive media through the coating film. The modified epoxy coatings presented good hydrophobicity, good thermal stability at 250 °C with only about 3 % weight loss.
The study was published in Progress in Organic Coatings, Volume 151, February 2021.
