BYD Solutions


We are all exposed to everyday life from the surfaces we touch, such as door handles, stair hand rails, public transport. The transfer of the bacteria and viruses is done mainly by tactile contact. BYD solutions can offer a revolutionary solution to help prevent the spread of bacteria and viruses.

With our effective and especially economic way to remove air and surface germs (bacteria, Viruses, Fungal etc) and odors, by treating surfaces with our titan affect CERTIBAC. This transparent coating with instant UV drying incorporating a permanent and lasting anti-bacterial action. Once applied the solution acts 24hours a day. CERTIBAC makes it possible to render the surfaces anti-bacterial and to reduce the risk of contamination crossed by tactile contact.


The control of hygiene is a real public health issue, particularly in the fight against nosocomial infections that every year kill more than 7000 people in France. The transfer of microorganisms is essentially by tactile contact being conveyed by the surfaces. Dexpert proposes a solution which allows to act durably and effectively against these contaminations.

The Dexpert Solution:

The CERTIBAC® matrix is a translucent surface treatment in the form of a varnish applied by micro-spraying using a HVLP (High Volume Low Pressure) device and then UV cured. It has a permanent and lasting antimicrobial performance thanks to a natural biocide associated (Colloidal Silver non nanoparticular). This multi-support matrix is a film-forming coating resistant to abrasion and chemical attack and its highly closed structure prevents the penetration of acidic and alkaline liquids. The microbial agents are destroyed on contact with this matrix as soon as their growth phase is activated. This coating emits nothing in the air (no VOC emission) and presents no danger; it complies with food contact within the meaning of EU Regulation 10/2011 and its amendments under the conditions tested.

CERTIBAC® has been tested according to the ISO 22196 standard by the COFRAC approved ACM Pharma laboratory.

In order to demonstrate the antimicrobial efficacy, various tests were carried out on a conventional plastic support treated with CERTIBAC ® and at different contact times (24 hours included) for the Escherichia coli strain, at a single contact time of 24 hours for the strains. Staphylococcus aureus, Enterococcus hirae and Candida albicans. Each test was performed in triplicate on a reference matrix treated with CERTIBAC® .

The results observed for the Escherichia coli strain on a conventional plastic substrate treated with Certibac® demonstrate the proof of the Inverse Hygiene Concept (CHI) and the efficiency of the process insofar as logarithmic reductions are very significant (greater than 5 log ) have been obtained reproducibly in at least 3 different tests.

Recurrent Infectious Risks:

Bacteria: Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Bacillus cereus, Enterococcus hirae, etc. Viruses: H1N1, H5N1, gastroenteritis, influenza, etc .. Mushrooms: Aspergillus brasiliensis, Candida albicans, etc … After establishing baseline contamination (inventory), deXpert’s solution reduces the concentrations of biological agents on sensitive and tactile surfaces, within the expected specifications (controlled environment).

CERTIBAC® Features

Immediate implementation ensuring rapid and significant reduction of bacterial contamination.

Requires no maintenance or energy consumption.

Allows a significant reduction of the microbial agents present on the treated surfaces, thus creating pandemic barriers.

Also has a coating resistant to abrasion and perennial over several years.

Treatment that acts permanently and facilitates cleaning ” easy to clean ”.

Application of the treatment requiring no prior work on surfaces, CERTIBAC® is translucent and dries immediately under UV.

High performance protection against stains, resistant to chemical agents.

Process that does not release VOCs (Volatile Organic Compounds).

Previous works

Surface treatments for door handles, sanitary areas, bank cash points, basically anywhere that can be touched.

This division offers services to:

  • Anti-Bacterial coatings for all surfaces
  • Removal of bacteria to surfaces and air
  • Reduction of the spread of viruses and germs
  • 10 year application process
  • No maintenance required
  • No Building alterations required


What is anti-bacterial coatings?

It is a system that once applied to any surface, including touch pads door handles, hand rails, basically anywhere that is touched will clean that surface of all bacteria.

what is the cost?

This can vary depending on areas that need treating. We are happy to provide free quotations for your requirements.

how long will the system work for?

Once applied the system will work and continue to clean your surfaces for UP TO 10 years.
