By combining Nanotechnology and Photocatalyst technology, TCM Asia managed to develop a solutions that can be applied almost on any substrates and it able to deliver a power functions to kill/decompose bacteria, viruses, biological pollutants, and bad odor. With the existences of UV lights or natural lights, this decomposition process will be expedited faster and harmful substances that stick on the surface are completely broken down into the carbon dioxide and other harmless compounds such as water.
