Photocatalytically active coatings

The photocatalytic coating of glass and metal surfaces, under the influence of UV light, purifies the air and eradicates germs and odours, e.g. on textiles.

The photocatalytic coating uses light to break down harmful substances such as smoke or unpleasant odours at the molecular level.

Material types and sizes

We offer photocatalytic surface coatings on glass and various metals

We coat sizes up to approx. one metre using our dip coating process. We can also use a spraying method to coat surfaces of very large dimensions.

Application examples

Breakdown of odours or pollutants

The degradation of odours, pollutants and germs on glass and metal parts is achieved by coating them with photocatalytically active titanium dioxide (TiO2) in the anatase crystal modification under the influence of UV light.

Water purification

The purification of water is carried out by photocatalytically active reactors. The water to be cleaned flows around the TiO2-coated large-area filters under irradiation with UV light. Structures with the largest possible surface area are used for this purpose in order to achieve the best possible purification effect.
