The air in our industrialised world is becoming increasingly polluted by harmful substances. In densely populated areas, air polluted by particulates from exhaust fumes, nitrogen oxides, and ozone is one of the greatest environmental challenges.

50 % of particulates come from secondary sources – particularly from ozone and NOx. StoColor Photosan, the innovative facade coating from Sto's paint generation of the future, iQ – Intelligent Technology, actively combats environmental pollution:

the surface-active paint effectively reduces the formation of particulates, and independently breaks down nitrogen oxides and ozone. A sustainable and effective concept for fresher air – clearly confirmed by external reports from various institutes.
