A coating is a protective cover that is applied to the surface of an object, usually referred to as the substrate. The purpose of applying the coating may be decorative, functional, or both. The coating itself may be an all-over coating, completely covering the substrate or only parts of the substrate. An example of all of these types of coating is a product label on many drinks bottles — one side has an all-over functional coating (the adhesive) and the other side has one or more decorative coatings in an appropriate pattern (the printing) to form the words and images.

Nanocoatings provide cost-effective solutions to industries with demanding applications and performance requirements. Coating manufacturers need to stay abreast with changing global trends such as the demands for
multi functionalities, waterborne, low VOCs, and Bio-based coatings.

The use of nanomaterials results in performance enhancements in wear and corrosion-resistant coatings and demonstrates significant enhancement in outdoor durability, and vastly improved hardness and flexibility compared to traditional coatings.



Unlike traditional coatings, nanocoatings can offer multiple functionalities in a single coating such as:

  • Anti-microbialism

  • Dirt and water repellence

  • Product longevity

  • Hardness

  • Gloss retention

  • Corrosion resistance

  • Thermal insulation & flame retardancy

  • Ultraviolet radiation stability

  • Anti-graffiti & Self-cleaning

Nanosilica is used to improve scratch and abrasion resistance, corrosion resistance, impact resistance, increase tensile strength, and superhydrophobic and easy-clean properties.

Being a rice-husk based Nanoporous Silica, Biosil can be used as a Bio-based nanomaterial to meet the increasing demand of the global Green Coating Market and can be customized for the manufacturing of a large variety of nanocoatings, including but not limited to:

  • Anti-fingerprint

  • Anti-corrosion

  • Anti-fouling & Easy-to-clean  

  • Thermal barrier & Flame Retardant

  • Self-cleaning

  • Abrasion & Wear resistance

  • Anti-icing & De-icing

  • Anti-microbial

  • Anti-viral

  • Anti-reflective

Biosil can also be used as a matting agent, anti-settling and anti-sagging filler for the manufacture of high performance coatings.
