Improved wear resistance and anticorrosion properties

Oct 30, 2021 | Industry News

A series of environmental-friendly polyvinyl butyral/phenol formaldehyde resin (PVB/PF) composite coatings with various PF contents were prepared by a solution blending method. The tribological and anticorrosion properties of the composite coatings as well as the influence of PF content were studied.

The results showed that the addition of PF can significantly improve the wear resistance of the PVB coating, and electrochemical impedance spectroscopy (EIS) results showed that the corrosion resistance of the composite coatings can also be significantly improved after immersing in 3.5 wt% NaCl aqueous solution for 30 days.

The researchers, claim that the good tribological and anticorrosion properties of composite coating are due to the uniform and dense structure formed by PVB and PF, which has good flexibility, high mechanical strength and excellent barrier properties. The study was published in Progress in Organic Coatings, Volume 158, September 2021.


Double layer powder coating to enhance corrosion protection

A novel epoxy resin modified PVC powder coating was used as a primer and pure PVC powder coating as a topcoat, for the corrosion protection of steel in a marine environment.

Test results revealed that the material obtained the highest adhesion and salt spray resistance when the epoxy content in the primer was 50 wt%. In contrast to the pure epoxy coating and the pure PVC coating, the EP-PVC coating exhibited an excellent corrosion resistance, owning to the good adhesion of the composite primer and the good barrier and corrosion resistance of the topcoat.

The study was published in Progress in Organic Coatings, Volume 158, September 2021.
