- Effective Against Viruses, Bacteria And Other Dangerous Pathogens
The active ingredient of SANPURE® is silver. A case study from the University of Regensburg recently demonstrated in a clinical setting: SANPURE® effectively helps to improve the hygienic situation between cleaning cycles. A study carried out by Eurovir showed that SANPURE® killed 90% of the viruses on the substrate after just one hour. After only 8 hours, the virus load was reduced by 99.99%.
- How Silver Works
The antimicrobial effectiveness of silver was first discovered in the 19th century. The oligodynamic effect (damaging effect on living cells) means that even very low concentrations of silver develop an antibacterial effect. This is enough to protect the material from microbial attack. If an appropriately coated surface comes into contact with moisture, silver ions are released, reach the surface and react there with the DNA of the bacteria and impair vital metabolic pathways. This leads to the death of the bacteria. A humidity of approx. 20 percent is sufficient for the reactions described. The effectiveness of silver ions against fungi and viruses has also been proven.
- Does Silver Work Against Bacteria And Germs
The antimicrobial effect of silver was first determined in the 19th century. Its oligodynamic effect (harmful effect on living cells) makes sure that even negligible quantities of silver unleash an antibacterial effect. This is more than enough to protect the material from microbial attack. When a coated surface comes in contact with moisture, silver ions are released, reach the surface and react there with the DNA of the bacteria, impairing vital metabolic pathways. This leads to the death of the bacteria. For this to happen, an air humidity rate of roughly 20% is more than enough. The effectiveness of silver ions against fungi and viruses has similarly been documented.
- Is SANPURE® Effective Against Viruses
SANPURE® was tested in a practical virucidal carrier test based on RKI guideline (1995) and ISO 21702:2019 against the bovine coronavirus (BoCV; strain: S379 Riems) – screening test S1. After a contact time of one hour the virus reduction amounted to more than 90 percent (lg 1.35). Almost no virus load could be demonstrated on the surface of the substrate after only eight hours. The reduction was more than 99.99 percent (lg 4.5).
- How Can One Test the Effectiveness of Sanpure® on One’s Individual Product?
GBneuhaus offers a three-stage sampling process. Within this process, customers and partners witness firsthand the effectiveness of the antimicrobial coating and can test the performance of their product after coating without much effort.
- How Long Does The Contained Silver Remain Effective and When is The Reserve of Silver Empty?
Current experiments and projections have concluded that the silver is effective for more than 20 years. The reserve of silver is larger than in silver salts or in layers that contain copper.
- Can Silver Leach Out or Diffuse From the Surface?
The silver will never diffuse to such an extent that the antimicrobial effect of SANPURE® is compromised in any way. An experiment in which the coated surface was wiped with HNO3 twice a day showed a life period of 55 years for the coating.
- How Can One Be Sure of The Antimicrobial Protection Offered by Sanpure® Especially Since The Coating Itself is Invisible?
Since SANPURE® contains fluorescent particles, it can be made visible under UV light if required.
- Does One Even Need to Clean Surfaces that are coated with SANPURE®?
In order to guarantee the best possible hygiene on the surface, standard cleaning cycles should be observed as usual. SANPURE® improves the hygienic situation in the intervals between cleaning cycles, prevents the growth and spread of bacteria, germs and fungi and disintegrates them gradually. While cleaning or disinfecting the surface only improves the situation temporarily, SANPURE® improves hygiene long-term.
- What Advantage Does Sanpure® Offer as Opposed to a Powder Coating With Silver?
SANPURE® is considerably thinner than a powder coating and hence requires the use of a much lesser amount of material. In addition, the product looks and feels exactly the same after being coated with SANPURE®.

Safety & Health
- Is it Dangerous for My Skin Cells to Come in Contact With a Surface Coated With Sanpure®?
No. A study by Dirk Hoefer and Timo R. Hammer substantiates: Antimicrobial active agents do not show any harmful effects on the ecological equilibrium of the microflora in healthy human skin.
- Does the Used Active Ingredient Harm the Environment?
SANPURE® contains a modern system for the controlled release of active agents and thus fulfills all requirements for biocompatibility. It is therefore considered physiologically harmless and thus does not harm nature.
