Our Technology

Green Innovation | Long-lasting Natural Coating Technology

airDefender® Quantum Antimicrobial Technology (QAT) is an antimicrobial and self-cleaning solution for a range of applications, from industrial and commercial to consumer products. Engineered through an advanced patented technology, QAT is transforming the science of nano photocatalytics.This innovative technology makes use of natural and sustainable resources and minerals and can be integrated into various raw materials and finished goods to introduce antimicrobial and self-cleaning properties. Nano photocatalysts have been used in a variety of applications and products, including in photocatalyst coatings. These nano photocatalyst coatings require constant light for their activation, so their use is often limited to exterior environments. They can be used to extend the life of exterior paint, reduce mold growth, and eliminate the environmental release of volatile organic compounds (TVOCs). QAT is the next-generation improvement in photocatalyst technology, bringing in a new generation of nano photocatalysts that are free from the requirement of a stable and constant source of light for activation. Moreover, the new technology can achieve 38x higher performance in antimicrobial and self-cleaning abilities, while lasting longer and being safe for use on all surfaces and around humans. It can even be incorporated into a liquid coating solution that consists of 99% water yet is able to provide surface protection, odor control, and antiviral protection. <br><br>Visit our blog to learn more about how QAT is revolutionizing nano-photocatalyst technology.

far beyond nanotechnology

Quantum Catalyst

In 2013, airDefender had a breakthrough and developed a Titanium Dioxide Antimicrobial Technology in quantum-dot size, lowering the size of active particles to far beyond the Nano definition. This smaller size allows more effective attachment to pathogens, removes the requirement for a stable and constant light source and dramatically improves performance. Since its development, airDefender has begun using this technology in commercial applications.


Able to kill superbugs – such as H1N1, E. coli, and MRSA – as well as other bacteria and viruses of concern, like SARS-CoV-2 and Human coronavirus 229E.


Able to outlast other additive technologies to deliver effectiveness ranging from hours to months, depending on the method of product incorporation.


Able to attach to surfaces stronger due to smaller particles with more contact points, increasing durability and wash resistance.



As a part of the airDefender mission to provide healthcare innovations, airDefender®'s quantum technology, which uses the Visible Light Responsive (VLR) catalyst, was ranked by a NASA research team as one of the top 3 best samples submitted in 2014.

An experiment published in the American Journal of Infection Control (AJIC) tested the effectiveness of the QAT surface coating. The results showed a remarkable 30% reduction in incidence of infection transmission in healthcare settings.
