Nano‐powder Coatings

The process of using a highly pure coating system is called nano-powder coating. In nano-powder coating, nano-powder is applied directly to the substrate in nano-powder solid form. Due to its absence of volatile organic chemicals and ability to provide exceptional corrosion protection, powder coating is one of the most durable finishes used on industrially produced goods. Compared to fluid-based coating techniques, this approach is more ecologically friendly since it produces fewer harmful chemicals, little organic waste, and does not utilize solvents. Due to its advantages in economy, ecology, the environment, and energy conservation, nano-powder coatings are recently taking over the liquid coatings industry in greater numbers. It differs significantly from conventional liquid paint in that it needs a solvent to unite the filler and bonding agent components in a suspended liquid. It primarily coats metals, including drum hardware, domestic appliances, bicycle and vehicle parts, and aluminum extrusions. This chapter mainly focuses on manufacturing nano-powder coatings, comparisons to liquid coatings, nano-powder curing process, methods to apply nano-powder coatings, and factors to consider while choosing nano-powder coating techniques.
