Iranian researchers from Isfahan University of Technology have succeeded in the production of transparent nanocomposite coatings with better mechanical properties in comparison with transparent coatings used in industries.
In addition to having longer lifetime, the transparent nanocomposites are cheaper and have higher adhesion to the substrate.
Nanosilica is one of the nanoparticles that has many applications in polymeric coatings industries as an agent to increase resistance to scratch. The aim of this research was to produce transparent nanocomposite coatings of acrylic polyurethane/nanosilica.
The mechanical properties of the nanocomposite were studied by applying it on the surface of carbon steel. To this end, two types of fumed and sedimentary silica were used as the filler in the coating.
