Enhancing properties of environmentally friendly alkyd coating with nanosilica

Abstract

In this article, environmentally friendly alkyd coatings with different nanosilica content (0-2.0 weight percent (wt%) were prepared for improving some properties as mechanical properties, corrosion protection, thermal resistance, etc. Nanosilica in coating was characterized by FT-IR. Effects of nanosilica on mechanical properties of environmentally friendly alkyd coatings with and without nanosilica such as adhesion, flexural strength and relative hardness and thermal stability were investigated. Coatings with and without nanosilica was also investigated with salt mist testing. Nanosilica with content of 1.5 wt% significantly improved mechanical properties, corrosion resistance, thermal oxidation resistance of environmentally friendly alkyd coatings.
