coatings: Why???

All bodies do have volume and surface properties

Coating can combine surface and volume properties.

Pilkington Deutschland AG, Gladbeck VMB / AWT, CT, 05-20115

Titanium-driller: Volume elasticsurface hard

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

m² per batch: ca 12 m²

Cycle time: 60-90 min

Must be processed to IGU immediately.

„active oxygen“

Function of Pilkington ActivTM

Pilkington Deutschland AG, Gladbeck VMB / AWT, CT, 05-201119

„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

hydrophilic effect / “no droplets”

Pilkington Deutschland AG, Gladbeck VMB / AWT, CT, 05-201125

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

Pilkington ActivTM does not mean „Never cleaning window“

Pilkington ActivTM means „less and easier cleaning windows!“
