We often think that all disinfectants work similar but they don’t. They all have their advantages and disadvantages. In general, disinfectants have three mechanisms of action or ways that they affect or kill a micro organism:

  1. Cross-linking, coagulating, clumping: usually Alcohol based or phenol based resulting in fire or strong odour risks.
  2. Oxidising: Like Chlorine, Sodium hypoclorite or peroxygen compounds some of which are corrosive in nature.
  3. Structure and function disruption: Like Quaternary ammonium compounds (quats) are some of the most widely used disinfectants today because of their broad spectrum effectiveness.


Quaternary ammonium compounds work by denaturing the proteins of the bacterial or fungal cell, affecting the metabolic reactions of the cell and causing vital substances to leak out of the cell, causing death.

Active Shield+: It uses QOS (Quaternary Organo Silane) which has additional property to stick the QAC compound to the base of applied material thus forming a self disinfecting long term disinfectant property on the coated surface.
