Photocatalytic Action of Titanium Dioxide

Photocatalysis is a process activated by daylight or artificial light that accelerates the oxidation of pollutants, transforming them into harmless compounds (sodium and calcium nitrates; carbon dioxide). The salts are deposited on the ground and are dispersed by wind and rain, while the carbon dioxide is dispersed in the atmosphere.

Titanium dioxide (TiO2) is the photocatalytic agent that absorbs light and promotes the decomposition of the pollutants without changing its chemical structure or its physical state. Its catalytic action is obtained by lending its electrons that are subsequently recovered from the environment.

Structures that are made or coated with RIMAC™ ACTIVE (which contains the photocatalytic active principle) reduce several airborne pollutants that in urban areas are commonly emitted by vehicles and heating systems: PM10 and PM2.5 fine dusts; aromatic hydrocarbons; and nitrogen, carbon and sulphur oxides ( NOX, COX, SOX ).

RIMAC™ ACTIVE reduces airborne organic and inorganic pollutants while preserving the estetic quality of the coated structures. It also  protects asphalt, concrete and iron from chemical and atmospheric agents.
