Anti-microbial Coating Technology

Our ground breaking coating technology with anti-microbial qualities has been developed together by BROMOCO International and our leading bio-chemist. This virtually invisible coating is suitable for application on-site, or in the factory. This makes Touch Anti-microbial coating systems the first of its kind providing high levels of long term anti-microbial protection. Anti-microbial is simply the term used to describe something that has the ability to resist the growth of microbes. While the term ‘antibacterial’ refers only to bacteria, Anti-microbial refers to a wider range of organisms including bacteria, moulds, fungi and others. The anti-microbial technology is incorporated into our coating at the time of manufacture. Once incorporated, the anti-microbial additives provides continuous, built-in, anti-microbial protection for the expected lifetime of the product. The silver ions on the surface of a material treated with the coating bind with microbes that come into contact with the surface, disrupting their normal cell function, which stops them from reproducing and results in the death of the cell.

Prevent growth of Fungi TOUCH will resist the growth of Mould, Moss Lichens and algae. TOUCH will protect the surface from UV degradation, acids, bleach, bird droppings, TOUCH protective coating will restore the colour and lustre of the original finish. Our coatings have been proven to provide over 10 years protection. BROMOCO International coatings provide a worldwide solution for the restoration and maintenance of all metal and coated substrates. A pioneer in the industry, we offer a complete range of architectural and maintenance services that help extend the life, increase the value, and enhance the beauty of exterior and interior architectural surfaces.

They are leading professionals in the field of anti-microbial technology and are dedicated to increasing awareness of the danger of harmful microbes and speeding the uptake of microbe-preventative technology across the globe.

An anti-microbial is something that prevents the growth and survival of microbes including bacteria, mould and fungi


As the graph below shows, on a product treated with Touch Anti-microbial coating systems the level of bacteria is reduced by up to 99% in two hours, with an 80% reduction in the first 15 minutes compared to an unprotected surface where they can proliferate at dramatic rates.

Tested Microbes Anti-microbial additives have been tested and found to perform against a wide range of microbes including bacteria, fungi and viruses. Some of the most common are listed below:

Bacteria ● ● ● ● ● ● ● ● ● ● ● ● ● ●

Acinetobacter baumanii Bacillus subtilis Campylobacter coli Campylobacter jejuni Clostridium difficile E.coli E.coli O157 Enterobacter aerogenes Enterococcus faecalis Legionella pneumophila Listeria monocytogenes Pseudomonas aeruginosa Salmonella enteritidis Salmonella typhimurium

Efficacy against all of these microbes can vary and specific data are available on request.


Bromoco International Coating Data

Touch METAL PROTECTION This ultra thin coating is virtually invisible with an average thickness of only 5 microns is the hardest of our coating range with a scratch resistance of H7 to H8 on the HB Pencil Scale, in comparison granite which is H6, making our coating 2 two points harder. Despite this it still remains flexible enough to cope with the expansion and contraction of the substrate. Our Anti-microbial technology will: ● Make a product more hygienic, if it is likely to host microbes harmful to human health. ● Keep a product fresher for longer, if it is likely to host odour-causing or staining microbes. ● Extend the lifetime of a product, if it is likely to host microbes which might degrade the surface.

The healing properties of silver have been known for a long time and the Touch Antibacterial coatings use these pure silver properties conferred to control microbial growth in an ideal manner: ● Silver is anti microbial

● Silver is non-allergenic

● Silver is anti-odour

● Silver reduces mite growth

● Silver is fungicidal

External and Internal Applications

Stainless steel is used extensively in our world both internally and externally. Most commonly used is the brushed finish used for its sparkle. The down side is that these items are high maintenance whilst also having the ability to harbour germs and bacteria. Once treated with Touch, the items will be protected and will require little or no maintenance depending on the location.


TOUCH Coatings In ACTION Bacteria Contaminates the surface

Touch Coated Surface

Silver ions in the coating immediately act against the contaminating bacteria

Touch Coated Surface

The silver ions combine with the bacterial within proteins and in the cell walls interfering with the DNA replication and promote the formation of reactive oxygen species

Years of protection

Touch Coated Surface

Bacteria die and the surface is cleaner and more hygienic for use.

Touch Coated Surface

Products protected by anti-microbial technology will negatively affect bacteria

PROTEIN DAMAGE Proteins are essential for biological systems of life. Any damage to these components causes the failure of essential functions such as energy production.

CELL MEMBRANE DAMAGE By disrupting the microbes membrane its structural integrity is compromised which can cause essential nutrients to leak out and catastrophic structural failure.

OXIDATIVE DAMAGE Anti-microbials can cause increased levels of reactive oxygen species which result in damage to the internal system of the microbe.

Touch ALL Hard surface PROTECTION This slightly thicker coating at around 12 microns is virtually invisible with a scratch resistance of H5 on the Pencil Scale, in comparison copper which is H 4, making our coating two harder. Despite this it still remains flexible enough to cope with the expansion and contraction of the substrate. Our Anti-microbial technology will: ● Make a product more hygienic, if it is likely to host microbes harmful to human health. ● Keep a product fresher for longer, if it is likely to host odour-causing or staining microbes. ● Extend the lifetime of a product, if it is likely to host microbes which might degrade the surface.

The healing properties of silver have been known for a long time and the Touch Antibacterial coatings use these pure silver properties conferred to control microbial growth in an ideal manner: Touch All Surface can be used on: ● Powder coated surfaces ● Painted Surfaces ● Plastic coated items ● Wood ● UPVC Windows and Handles ● Plastic Light switches ● Plastic Electrical points ● Ceramics ● Tile Grout ● Hard plastics (test a mall area first) ● Copper ● Brass ● Radiators ● Ventilation grills ● Ventilation ducts Touch all surface may be applied to any hard surface but always test a small area first Touch All Surface is resistant to: 1. Bleach 2. Acids 3. Bird droppings 4. Staining Applied correctly Touch Coatings are guaranteed to NOT crack, peel or discolour

Touch Anti microbial coatings versus traditional cleaning methods

Cross section of a deep cleaned surface

Cross section of surface Contaminated A perfect breading ground for bacteria Deposits may contain: Sweat, grease, skin, excrement, dirt, blood, spit and other body fluids Usually seen as fingerprints and stains

Cross section of surface after a normal cleaning Traditional cleaning methods often just push the dirt deeper into the material surface allowing bacteria to thrive just below the surface

TOUCH hard coating applied

Cross section of surface newly coated with Touch Touch coating provides surface and subsurface protection with a thickness of 3 to 5 microns on metal surfaces making it virtually invisible and a hardness rating 2 points higher than granite will last for many years on untouched surfaces

Effects of long term ware of Touch coatings On surfaces that receive high use ware will occur however once the layer of coating above the surface has been worn down however the sub-surface is still providing excellent protection and will only continue to decrease at the same rate as surface material

Traditional Cleaning Methods

Traditional cleaning methods can result in forcing contamination deeper into the surface of the substrate this combined increased prevalence of antibiotic resistance and reports that cleaning agents are having a reduced effect on microbial colonisation

Long term effects of ware Most hard surfaces are porous and can harbour germs and dirt. Touch Coatings are absorbed into the surface and provide high levels of protection below the surface. Making the surface fingerprint and stain resistant for many years after the top coat has worn thinner.

History Bromoco coatings have a been in use for over 15 years with proven real-life durability with hundreds of applications Worldwide including iconic buildings and landmarks such as the McLaren formula one headquarters in Woking completed in 2009 and Canary Wharf London in 2011. The original application at McLaren was internal and then in 2010 the entire building was coated. Upon completion a 4-year guarantee was issued with advice to re-coat in year five, however the building has outlasted its original guarantee 3 times as the coating is still working today providing high levels of protection. In 2013 founder and technical director Mr Anthony Semple along with leading biochemists was able to add silver ion anti microbial to the formula. This was an amazing achievement bearing in mind the coating is crystal clear and only 5 to 8 microns thick. The resulting TOUCH Anti microbial coatings was successfully tested early in 2014. The testing was to confirm that the already proven silver ion technology within the already proven coating was performing successfully within the coating. See HERE for test results Although we did not confirm the anti-viral qualities at that time, we were confident that the technology had previously been test and proven to be effective against the H1N1 influenza and feline corona viruses would perform equally as well within our coating.

Silver Ion stability The silver ion technology within our TOUCH Antimicrobial version of our coatings

is not

UV stable. Our coatings contain UV blockers so the silver ion technology will remain effective for the lifetime of the product, Because the silver ions are encapsulated within our coatings, they are guaranteed to not leach out and contaminate water as silver ions are considered a biocide and must not enter and contaminate the water table.

Testing and future proofing We have become under increasing pressure due to the current pandemic to provide test results for our coatings effectiveness against enveloped viruses such as COVID 19. We are currently having 15 sample tested at an independent laboratory and expect to have the certificated results by July. We have chosen to have the ISO21702 testing as this will prove the coatings effectiveness against all enveloped viruses including the whole of the coronavirus family ensuring that all environments protected with TOUCH Antimicrobial coatings will be protected now and for the future from known and unknown viruses that will come along in the future. As previously stated, other products such as paints and plastics that have silver ion content have already proven to be effective, so this test is purely a formality. See HERE 2 Levels of Graffiti protection Because TOUCH Antimicrobial coatings are a film coating, they entirely seal the surface they are protecting resisting ingress of paints and dyes. There are 2 forms of graffiti, water based such as leather dyes/paints and solvent based such as cellulose paint, permanent type markers. Please see this short video to see how TOUCH Antimicrobial coatings deal with them. HERE

Proven Durability TOUCH Antimicrobial coatings can be maintained indefinitely due to its unique self-annealing and self-levelling qualities. So, if the coating is damaged by external force it can be fully and invisibly repaired at any point during its lifetime without the need to remove the entire application allowing small areas to be repaired if needed. Our coating has more than 3 times out lived the original guarantee period in real life applications in all environments both internally and externally around the world. We provide a 2-year application guarantee and 5-year manufacturers guarantee when applied by trained technicians providing total peace of mind. A copy of our guarantee can be supplied upon request

Other products on the market comparison We are often compared to other products that have appeared on the market since the break of COVID 19. The main difference is that TOUCH Antimicrobial coatings are a film coating which seal and provide 100% protection of a treated surface. I have listed two of the main types below and given my opinion and experience of them. Nano Type products These products are probably the most common on the market with some bold and questionable claims such as providing protection for 6 month or more. By the very nature of these products the durability in a real time situation is questionable as for the most part the Nano sized very sticky particles are suspended in a solvent / alcohol solution. They are wiped onto a surface and the solvent evaporates /flashes off leaving the particles to stick to the surface. As these particles are sticky, they also stick to anything that touched them including hands and clothing quickly leaving the surface unprotected. In our tests on door handles there was little left after just a few hours. My other concerns are regarding the silver ions as they are not UV stable and when exposed to UV light their effectiveness diminishes, unlike TOUCH Antimicrobial coatings Nano type coatings offer no protection from UV light as they are not a film. Also, I am concern about the environmental impact of the silver ions being released when touched or simply drop off over time, again unlike TOUCH Antimicrobial coatings Nano coatings offer no way of encapsulating the silver ions thus preventing leaching. Silver ions are considered a biocide and should be treated with caution and It is worth noting that in Germany BUND criticized the product, claiming that considerable amounts of silver could enter sewage plants and seriously trouble the biological purification process of wastewater. Friends of the Earth has also claimed that silver nano particles have a toxic effect on different kinds of living cells. Long-lasting 30-day disinfectants These products are usually offered as a fogging or bomb process which means that they are atomised or put into the air via fogging equipment and allowed to fall onto surfaces. Firstly, this is not a perfectly accurate form of application as there are no guarantees that all aspects of all surfaces are treated such as undersides nooks and crannies where bacteria and virus like to hide and breed. This also applies to any form of product applied in this fashion. I have no doubt that these products will remain active for a period in a laboratory test where they are untouched however in a real-life test, they wipe off with general use very quickly and off little or no durability. These products are designed to clean down surfaces and would offer some level of protection on Textiles.
