Avoiding the contamination of surfaces is of major importance today, especially to prevent the spread of the SARS-COV-2 virus, since the coronavirus can remain infectious for days on surfaces (up to 72h on plastic and steel). Maintaining microbiological hygiene on various kind of surfaces is also of interest for the pharma and cosmetic industries as well as the food sector and other industries: for bottles, containers, nozzlers, applicators accessories…
The French company has developed and patented a natural protection technology that answers those needs; the process being in addition a cleantech and easy to integrate in the manufacturing process of the final product.
This protection relies on a microparticle technology which is then integrated to existing processes:
Spherical mineral microparticles (2-5 μm) are chemically synthesized thanks to the company’s patented process.
INTEGRATION IN EXISTING MANUFACTURING & INDUSTRIAL PROCESSES
- For layer application with coatings and paints: the microspheres are mixed with coating/paint before application (spray gun,...)
- For integration in the entire thickness of the plastic materials: the microspheres are mixed by granulation/extrusion compounding to obtain plastic pellets, enriched uniformly with the microspheres. Those pellets are then transformed (parts, fibres, coating films…) with existing processes.
When the spheres are in contact with air humidity, a catalytic reaction takes place and creates reactive species that kill germs (viruses, bacteria, mold and yeast).
The efficiency against human coronaviruses and bacteria has been tested and certified by independent laboratories, according to ISO 21702 (viruses), ISO 22196 (bacteria) and JIS 2801:
- Coronavirus strain 229E: 99% destruction in 1 hour and >99.9% destruction in 24h.
- Bacteria: >99.999% in 24h
In the current period of health crisis, it can benefit hospitals, retirement homes, schools to protect tables, working areas …. It can also benefit all infrastructures open to public and/or subject to high hygiene standards.
Biotech, cosmetic and food industries can also be interested by adding easily a natural antimicrobial protection to their products (bottles, containers, nozzlers, applicators accessories…)
The French company is looking for technical cooperation with brand owners to develop and market a common product (their actual product or a new one integrating the French company’s technology).
