Intelligent Technology + Design (iQ) coatings, referred to as Sto iQ Technology, use optimized product properties. StoColor Lotusan uses biomimicry to create an exterior coating that when water hits the surface, it forms into droplets and flows off, taking dirt particles on the surface with it. StoColor Climasan is an indoor coating that attracts harmful substances and odorous gas molecules. When exposed to a light source, a catalyst in the coating reacts, breaking down the pollutants and neutralizing the odors.
