No place for bacteria – the flooring solution
21 July 2016
Bacteria can remain on surfaces for days, weeks of months. Surfaces with antibacterial effect represent a major contribution to hygiene and protection from bacterial contamination. The increased occurrence of bacterial pathogens resistant to different antibiotics (so-called multiresistant pathogens) such as e.g. methicillin-resistant Staphylococcus aureus (MRSA) raises general concern. In particular, the inadequate implementation of prophylactic hygiene measures is to be seen as reason for the sharp growth in the germ colonisation. It is also known that e.g. MRSA can survive many weeks on sterilised surfaces.
A sterile environment alone is nowadays far from sufficient to combat multiresistant bacteria. The KLB-Coating Systems with antibacterial effect were tested for their antibacterial efficacy according to ISO 22196:2011-08 and JIS Z 2801:2000.
Escherichia coli and Staphylococcus aureus are used as an example of many different bacterial strains. In the test specified in the standard, the bacterial strains are applied with a nutrient solution on a reference sample and on the antibacterial coating or sealing. Subsequently, the samples are incubated for 18 hours at 35 °C and sufficient humidity.
The antibacterial efficacy results from the difference of the germ counts on the samples and the reference samples. The antibacterial test of our products was carried out by the Hohenstein Laboratories GmbH & Co KG test institute, confirming a high antibacterial efficacy.
The decorative and antibacterial coating system KLB-SYSTEM EPOXY EP 202 AntiBak and the product family KLB-SYSTEM POLYURETHANE PU 806 E AntiBak have been tested with regard to their volatile organic compoundsn(VOCs). The established VOC values were below the limit values specified by the AgBB (Committee for Health-Related Evaluation of Building Products) scheme. These products have been approved by the German Institute for Structural Engineering [Deutsches Institut für
Bautechnik (DIBt®)] for use in living and working spaces.
The antibacterial products of KLB Kötztal Lacke + Beschichtungen GmbH were tested for their antibacterial efficacy at the Hohenstein Laboratories GmbH & Co. KG test institute. A strong antibacterial action was assigned to each product. The bacterial contamination of the surface material is reduced by more than 99.9 % thanks to the antibacterial coating and sealants.
- Fire testing
The antibacterial coating systems of KLB Kötztal Lacke + Beschichtungen GmbH were tested for fire behaviour and according to DIN 13501-1:2010-01 classified as Bfl-s1 due to their low inflammability. Please ask about the tested system configuration.
The sealing KLB-SYSTEM POLYURETHANE PU 806 E AntiBak – R10 was tested according to DIN 51130 at an inclined plane for its foothold and slip-resistance and rated with R10 according to BGR 181. In areas where food is manufactured and processes, the Employer’s liability Insurance Association often demands higher levels of slip-resistance. KLB-SYSTEM PU-BETON was tested in different design variants with R9, R10, R11, R12 and R13 and rated.
- Suitability for foodstuffs
The product family KLB-SYSTEM PU-BETON and KLB-SYSTEM POLYURETHANE PU 806 E was examined according to food law requirements at the Institute Nehring GmbH (Institute for the analysis of food, consumer products and the environment). The final analysis showed that the products meet the requirements according to § 31 (1) German Foodstuffs and Consumer Products Act. The coatings did not release any substances to food, which could be questionable in terms of health, odour or taste.http://www.engineersjournal.ie/2016/07/21/industrial-floor-systems-bacteria/http://www.engineersjournal.ie/wp-content/uploads/2016/07/pot-1.jpghttp://www.engineersjournal.ie/wp-content/uploads/2016/07/pot-1-300x300.jpgSponsoredbacteria,fire,food,pharma
