Our coating is a stable nanocomposite material, that is relatively pH neutral and non-toxic to humans (passing SGS RoHS testing), with no toxic organic solvents.
Our coating is a semiconductor material, after light radiation the TiO2 light absorption, valence electrons are excited into a higher energy level, valence band into conduction band producing electron hole pairs. Electron hole pairs will react with water in the air to produce OH free radicals. These free radicals can oxidize TVOC and formaldehyde forming water(H2O) and carbon dioxide (CO2) with no secondary pollutants.
No, our coating is an inorganic semiconductor material, as long as it is present on the surface of the object, it can be activated by light to oxidize organic residue. Biogard Technology acts as the catalyst for the reaction but does not change after the reaction, so its effect does not weaken over time.
Not at all, Biogard Technology has obtained FDA registration and listing, as well as Swiss SGS & China Center for Disease Control skin and oral cytotoxicity reports showing no cytotoxic responses in cells. Alongside USA MicroBac antiviral and MedicalCentre antibacterial reports, Biogard Technology has done tests for various globally recognized standards and quality benchmarks.
Please see the antimicrobial test reports, Biogard Technology can still achieve over 99% antimicrobial efficacy under no light conditions (24hr).
Biogard Technology is close to pH neutral and non-toxic, its antimicrobial coating is long lasting without the need to reapply constantly. It can reduce and prevent epidemic and cross infection in indoor environments in two ways:
1. It can kill bacterial cells by reacting with thiol groups in cells.
2. It can decompose bacteria, viruses and other microscopic organisms at the same time not affecting patient's health as it is non-toxic to humans.
Therefore, all coated areas do not need to be quarantined. Compared with traditional disinfection methods, normal isopropyl alcohol disinfection methods only works short term. Over time, bacterial numbers start to multiply and the risk of infection increases. Bleach disinfection requires patients to leave the area and leaves a strong after smell that can cause irritation to some patients.
General disinfecting practices are still required because after coating in situations with high volume of people or contaminants - the surface may be affected and lose some efficiency. We recommend using traditional disinfecting along-side Biogard Technology to have an even greater efficiency at protecting against contamination and disease transmission.
Biogard Technology consists of singular nano particles that use nano technology to dope nano silver onto the surface of nano titanium dioxide alongside nano dispersion techniques to produce Biogard Technology nanocomposite material. This technology is patented in several countries and is different than many of the photocatalysts on the market today.
Many of the photocatalyst material on the market contain solvents with added nano silver but need to distribute it evenly on photocatalytic material dispersants. The added chemicals are what make the solution acidic with a translucent white to pale white colour and some sedimentation. These solvents and dispersants also have strong odours that are proven to be harmful to human health. Other proclaimed photocatalysts should be carefully considered for its quality despite the price difference.
In general, human skin cells have their own protective measures; therefore do not affect skin cells as much. Biogard Technology has sent our product to do skin cytotoxicity testing at the Chinese Center for Disease and Control and the results showed that Biogard Technology showed zero cytotoxic responses to cells, with LD50>5000mg/kg.
Normal maintenance only requires wiping gently with a wet cloth.
