antikondensatbeschichtung, anti condensation coating

Anti condensation coating  – always dry surfaces

  • Mechanism: micro-structured surface spreads droplets → high evaporation → dry surface.
  • Typical system: ~3 coats, ≥900 g/m² total → ~500 µm DFT
  • Application & colours: brush / roller / airless, all colours.
  • Quick check: use fRsi (see calculator below); rule-of-thumb target ≥ 0.70 per DIN 4108-2-type guidance.

An anti condensation coating will help to solve the following problem:

Condensation of water occurs, when humid air gets in contact with a cold surface. Everybody, who wears glasses knows this problem, when entering a warm room from the cold outside. The glasses get covered with dew water very fast. The visibility is impaired.

Condensation can mainly be found in housing (bad insulation) and in the food industry. In the latter the combination of very humid interior air and often old infrastructure leads to condensation. Cold pipes in a humid environment can also be a problem.

The result of condensation is in most cases mold. There are three requisites for mold:

  • spores in the air (which is normal)
  • nutrition for mold (which can be dirt, plaster, fibres etc.)
  • high local humidity

If those three conditions occurs a the same time at the same place, then spores will germinate and mold will grow.

If only two conditions occurs, spores will not germinate and mold will not grow. Applying the anti-condensation coating will keep a surface dry – no mold can occur.

A calculation tool

There is a simple calculation method to determine whether the application of an anti-condensation coating is appropriate.

The calculated fRsi value is a measure of the quality of the existing thermal insulation. The lower this value, the poorer the insulation. Poor insulation can lead to condensation, which in turn can lead to mold.

Now measure the following temperatures in situ and calculate the fRsi value:

Our anti condensation products

We offer two types of anti-condensation products:

  • a coating, which can be applied in many different ways, such as rolling, painting, spraying.
  • a plaster for heavy-duty problems

How does it work

Anti-condensation coatings have a microscopically finely structured surface that breaks the surface tension of the condensation water and ensures that the condensation water is distributed over a large area (See also the instructive video). The result is very high evaporation rates and, as a consequence, dry surfaces.
If you look at the following time lapsed video carefully, you will see how fast the water drop on the left hand side will dry-off. On this side our anti-condensation coating is applied, on the other side, a commonly used paint is applied.

Below you will find some more information about the products.

FAQ

All available technologies can be used: brush, roller airless. Let us know in advance, which technology you intend to use.

When you apply three layers (at least 900g per square meter) the dft is about 500-700 microns.

All colours are available.

Basically on all sustainable surfaces. Please let us know, if you have an exotic surface. A primer might be used beforehand.

No, the anti condensation coating has a surface function. If this layer is covered, the functionality disappears.

Basically yes! It is furthermore much cheaper, about one third, considering the product itself and the application.

It depends on the surrounding, but basically as long as any other coating. When the surrounding is dusty and dirty, then the micro structure of the coating will be sealed and the functionality is hindered. Cleaning with fresh water would be the thing to do in such a case.
