1. Production techniques2. Working principle3. Properties and how these are measured

- lab scale- customer side

4. examples


coatings: Why???

All bodies do have volume and surface properties

Coating can combine surface and volume properties.


Titanium-driller: Volume elasticsurface hard

Glass: thermal insulation, solar control, self cleaning, low reflexion


thermal evaporation


Thermal evaporation

m² per batch: ca 12 m²

Cycle time: 60-90 min

Must be processed to IGU immediately.

At the end of the tin bath TiO2 is coated at about 600°C using CVD.

Durability of Pilkington ActivTM

TiO2 - SchichtSperrschicht

„active oxygen“

Function of Pilkington ActivTM


„active oxygen“– active cleaning process– thin organic deposits will be removed

completely (e.g. finger prints)– thicker deposits will be loosed (bird dirt) easy to clean



water

Float - surface

water

Activ - surface

hydrophilic effect / “no droplets”



hydrophilic effect / “no droplets”– intensifies the cleaning effect of water– better “look through” during the rain– no water deposits after the rain– less outer condensation



„less outer condensation“



Pilkington ActivTM does not mean „Never cleaning window“

Pilkington ActivTM means „less and easier cleaning windows!“





4. examples


Photocatalytic effect:• decomposition of organic dirt• Methylen blue

Hydrophilicity• Contact angle

Photocatalitic effect + Hydrophilicity• Spray nozzle test
