TroBloc M prevents microbes such as bacteria and fungi present on the surface from continuing to multiply. To achieve this antimicrobial effect, Trobloc M uses modern silver ion technology. The additive, which is non-toxic to humans, acts in purely physical manner – through the transfer of silver ions- to prevent the growth of microbes. This action inhibits the reproduction of strains of bacteria. The bacterial action takes effect in very litttle time, as has been proved and certified by the Swiss company, Ciba Spezialitatenchemie AG in Basel. Its reliable effectiveness with respect to the bacterium, MRSA, has also been proved in laboratory tests in Ciba.
