THE JOURNEY FROM ASH TO CASH

PROVIDING SUSTAINABLE SOLUTIONS FOR THE PAINT & COATINGS INDUSTRY

BSB Nanotech is the first enterprise in the world to successfully produce nano-porous silica from rice husk ash on a commercial scale. Located in the Mekong Delta, the rice bowl of Vietnam, the company utilizes agricultural by-products from rice processing to create high-purity, environmentally friendly bio-based silica.

BSB’s Nano Silica is widely applied across various industries, including paints and coatings, rubber, plastics, cosmetics, pharmaceuticals, and agriculture. As the leading developer and manufacturer of rice husk (RH) silica-based additives, BSB is at the forefront of innovation, advancing a bio-based and circular economy through the commercialization of its products under the global brand Biosilico.

This achievement is underpinned by patented extraction technology, developed through years of dedicated research and development, and supported by an ISO-certified manufacturing process that ensures consistent product quality and compliance with international standards.

The Future of Coatings Rooted in Nature

Nanocoatings provide cost-effective, high-performance solutions for industries that demand exceptional durability and functionality. Compared to conventional coatings, nanomaterials significantly enhance wear resistance, corrosion protection, UV and weather durability, surface hardness, and flexibility.

Biosilico’s products feature amorphous silica derived from rice husk, developed by BSB Nanotech as a bio-based nanomaterial engineered specifically for advanced coating applications. Available in hydrophilic grades, these silica additives serve as matting agents, anti-settling, and anti-sagging components in high-performance coatings.

Key customizable performance enhancements offered by Biosilico include:

Enhanced scratch and abrasion resistance
Improved corrosion protection
Superior impact resistance
Increased tensile strength
Easy-to-clean surface functionality

Ongoing R&D has expanded the Biosilico product line to include hydrophobic, superhydrophobic, and oleophobic silica formulations, offering versatile surface protection solutions across a broad range of substrates.

Hydrophobic Coatings

Biosilico hydrophobic silica is suitable for use on glass, metals, polymers, ceramics, ship hulls, concrete, and textiles, delivering key functional benefits such as:

Water repellency
Anti-corrosion
Anti-fouling
Anti-microbial
Self-cleaning

Superhydrophobic Coatings

Engineered for similar substrates, Biosilico’s superhydrophobic formulations offer enhanced surface performance, particularly in extreme conditions. Benefits include:

Anti-icing and anti-wetting
Advanced anti-fouling
Improved anti-microbial resistance
Superior self-cleaning properties
Extended corrosion protection

Oleophobic Coatings

Biosilico’s oleophobic silica enables surfaces to repel oils, greases, and other non-polar contaminants, making it ideal for applications where cleanliness and chemical resistance are critical. Key features include:

Oil and chemical repellency
Stain resistance
Easy-to-clean surfaces
Improved longevity in oily or greasy environments

Together, these advanced coatings position Biosilico as a comprehensive, bio-based solution for industries seeking sustainable and high-performance surface treatment technologies.
