Coatings and Paints - Nanotechnology

What are Nanotechnology-based Coatings and Paints?

Nanotechnology-based coatings and paints incorporate nanoparticles or nano-structured materials to enhance their properties. These coatings provide benefits such as increased durability, enhanced UV protection, and improved resistance to scratches and corrosion.

How do Nanoparticles Enhance Paints and Coatings?

Nanoparticles can modify the surface properties of paints and coatings at the molecular level. For instance, titanium dioxide (TiO2) nanoparticles are used to improve UV resistance, while silicon dioxide (SiO2) nanoparticles enhance scratch resistance. These modifications result in coatings with superior performance characteristics.
