Biohazard and Toxic Chemical Deactivation Coating – ‘NT-M’
KST’s Biohazard and Toxic Chemical Deactivation Coating, named ‘NT-M’ after the successful test sample number, is a catalyst activated by ambient levels of ultra-violet light and acts to decrease the activation energy of a given reaction; thus enabling decomposition (oxidation) of biohazard contaminations. NT-M acts as a preventative system that provides proactive defense against biohazards and toxic chemicals and complements standard measures recommended by health authorities.
The key enabler of NT-M’s commercial viability and competitive advantage is its low-cost production process. The cost of NT-M enables this technology approach to be introduced into mainstream commercial market segments, expanding beyond the current realm of laboratory settings and niche applications. Mass-production quantities are feasible and can be achieved with commercial off-the-shelf equipment.
Independent Testing Results
Independent tests indicate that NT-M is effective in destroying bacteria hence significantly improving hygienic conditions. NT-M is also proven effective in the decomposition of pollutants and toxic chemicals, such as VOCs.
Bacteria Effects Testing. Independent anti-bacteria testing were conducted in accordance with Japanese Industrial Standard-L-1902:2002. Fabric samples were coated with high viscosity NT-M and low viscosity NT-M. It should be noted that due to standard testing protocols, tests were conducted in the dark after only a brief 2-hour coating activation exposure to UV light. Longer periods of UV exposure significantly increases coating effectiveness and extends the duration of performance in darkness. As indicated in Figure 2, testing results demonstrated over 99.9% anti-bacterial effectiveness.
VOC / Odor Reduction Testing. Independent testing was performed for VOCs. The gasbag method utilized UV lamps with Acetaldehyde as the test gas. NT-M coated fabric samples were prepared into the required sizes and placed into the testing equipment. The coated substrates were exposed to UV rays (1.0 mW per square cm) for two hours at room temperature (20-25 degrees Celsius). The elimination rate of the VOC (Acetaldehyde) was then measured and the NT-M coated fabric samples demonstrated more than 98% removal rate of VOC. In the same fashion, NT-M coated Aluminum substrates were also prepared and placed into the gasbag test equipment. NT-M coated aluminum samples demonstrated more than 92% removal rate of VOC
NT-M has a very wide operating band regarding length the product may be stored, application coverage, and effective temperature which ranges from freezing to boiling – significantly better than paint.
