  • Bio-Kil treatment is Cargico’s know-how. The subjects need to be treated with Bio-Kil will go through several pretreatment process (similar to catalyst treatment). In the end, Bio-Kil may be “sprayed” onto a surface to form strong binding; or in the case of an object, the item (filter, clothing, other solid object) may be dipped in solution with Bio-Kil to complete the process. In either case the molecular binding occurs immediately the solution contacts the pretreated surface. Once dried the Bio-Kil protective properties are active and the surface may be washed down with water and mild soap/detergent, if desired, to remove any drying marks and residues.For various plastic products it can be applied by using specially produced resins during the manufacturing process. Some limitations exist with regards to heat levels during the molding process. The Bio-Kil R&D team can review and consult with the customer.
  • Washing the surface after application will not harm, damage or reduce the anti-bacterial properties of the Bio-Kil treated surface.
  • Textiles may be washed in commercial laundries or domestic washing machines with detergents for up to 50 times before requiring re-treatment.
  • The life of the surface material. With siliceous surfaces such as glass and ceramic the nano-needles have a permanent molecular bond and therefore become themselves a part of the surface materials – in effect lasting as long as the surface material life-span.
  • Treated textiles (clothing, bedding) are generally carbon-based substrates, which also provide a permanent molecular bond, but not as strong as the case with silicates. In this case it is recommended that textiles treated with Bio-Kil may be washed up to 50 times before requiring re- treatment with Bio-Kil solution, in order to maintain anti-bacterial effectiveness.
  • For the most part – YES.
  • However, a few things can diminish effectiveness,
    o effectiveness may be reduced if the nano-sized needles get covered under a film of grease or other lasting dirt, in this instance regular cleaning of the surface is required, and when cleaned the protective properties of the Bio-Kil treatment are restored.
    o Aggressive chloride can affect the bond, and slowly wear it out.
    o Strong forces can break the bonds or the nano-needles, so for example in the case of a chopping board or surfaces that endure significant physical friction and wear &tear it may not be a long-lasting situation. Regular machine washing with detergents will also eventually reduce the effectiveness.
    o There are some surfaces such as polymer-based materials where the molecular bond is less strong, in which case the treatment would last less time – generally for 1-3 months depending on usage and exposure, after which it can be re-treated or replaced.
    o In the case of repeated washing in detergents and washing machines, re-application of Bio- Kil is recommended after 50 washes.
  • YES. In almost all cases it could be easily re-applied. The decision to re-apply Bio-Kil treatment vs. to replace the surface is at the discretion of the decision maker and depends on the substrate and its cost.
    o For example, in a temporary or disposable situation such as filtration – a paper air filter used in air conditioning systems, it may be more cost effective to replace with a new treated filter that would restore BOTH anti-bacterial AND particle filtration properties.
    o In the case of a ceramic filter there are two options: Replace the complete filter with a new Bio-Kil treated one OR simply clean/recycle the filtration media, and for highly sensitive areas/contracts retreat with Bio-Kil.
    o In the case of walls or floors, it is more effective to regularly clean areas; and re-apply Bio-Kil to high traffic / high exposure areas at longer intervals (annually or longer, depending on wear factors)
    o In the case of textiles, re-apply after 50 washes.
    o The nano-sized needles do not dull or lose their negative ion charge; and on the most silicate surfaces are unlikely to come off in sufficient numbers to decrease effectiveness.
  • Mold will not grow on a Bio-Kil treated surface, as mold is a bacterial process. Bio-Kil in effect acts as an anti-mold / anti-fungal surface treatment as well. If mold does grow, it indicates that either that surface was not treated (in which case apply Bio-Kil to the area) OR the treatment has deteriorated due to wear or due to dirt/oil/grease/other contaminants covering the nano-needles (in which case wash down area to remove contaminants and restore effective anti-bacterial protection).
  • The nano-needles can become clogged if, for example, an oil/grease film covers the surface in which case the film will act as a barrier for the bacteria or virus cells to come into contact with the nano- needles.
  • The nano-needles themselves will not become dulled over time. The crystalline nature of the molecular bonding means they would likely snap under consistent high force than to become progressively less sharp.
  • Yes, there are some limitations to surface substrate materials – we know that Bio-Kil does not bond well with non-porous shiny surfaces such as stainless steel, aluminium and chrome.
  • At present, our testing indicates that Bio-Kil bonds and performs very well (strongly) on siliceous surfaces (glass, ceramic, etc.), and well with carbon (wood, paper, textiles, cotton, silk, etc).
  • Bio-Kil can also be included in the chemical mix with some resins used for plastic molding to produce plastics with inherent anti-bacterial and anti-viral properties. This is limited to those plastics which do not require very high temperatures for manufacture lower than 60 deg C.
    • Bio-Kil can also be introduced as an ingredient into acrylic (water-based) paints to produce paint with inherent anti-bacterial and anti-viral properties.
  • There are no specific maintenance requirements. In general, Bio-Kil treated surfaces benefit from regular cleaning routine, and can be periodically spot-tested for effectiveness using a color test which reacts blue to indicate presence of Bio-Kil.
  • Positively charged bacteria or virus cells do not exist in nature – therefore there is no bacteria/virus that would be repelled from the nano-needles. In nature all bacteria and viruses are negatively charged, which are naturally attracted to positive ions.
  • Bio-Kil has been tested effective in eliminating Legionella pneumophilla, Escherichia coli (e-coli), Salmonella typhimurium, Listeria monocytogenes, Staphylococcus aureus, MRSA/ORSA, Pseudomonas aeruginosa bacteria and H7N2 avian influenza virus and coronaviruses such as SARS.
  • Pricing of Bio-Kil solution will be different according to the service mode (long-term, short-term or one-time service), the environmental setting and the complexity of the solution. Pricing needs to be fully evaluated by Bio-Kil team in order to have a proper quotation of a project.
