SOLAR RADIATION - A MAJOR THREAT FOR THE FACADE


 

Solar Radiation is source of two threats to the
facade:

 

Free radicals

 

Exposure to UV


What are free radicals?

They are formed in the plaster coating by photochemical processes under the influence of sunlight and harmful UV radiation it contains.

Free radicals are destroying the polymer bonds, which in turn are no longer able to hold the pigments in their structure.

What are the effects of the solar radiation?

  • Fading colours
  • Embrittlement of the plaster
  • Cracking and blistering
  • Plaster delamination
  • Facade becomes vulnerable for algae and fungal attack

THE SOLUTION - CT 76 SOLAR PROTECT with UV Protect Technology

 

We have developed Ceresit CT 76 as a solution to the problem of the destructive influence of solar radiation.

The key element of this innovative plaster is the new UV Protect Technology based on light stabilizers - UV absorbers and free radical scavengers. The light stabilizers effectively combat free radicals and their destructive impact on the products's coating.

Ceresit CT 76 contains an optimal combination of silicon and elastomeric dispersion, which provide us excellent flexibility, high level of diffusion, resistance and low water absorption.


UV Protect Technology is based on UV absorbers and free radical scavengers which are activated by the solar energy and oxygen.

They become an invisible shield, which ensures the safety of the plaster and thus of the facade.

UV absorbers

They absorb damaging UV radiation like a filter on your facade.

Thanks to the UV absorbers:

  • facade temperature is lower
  • the plaster is protected even in deeper film sections

Free radical scavengers

Their task is to protect the facade against the effects of free radicals, which destroy polymer bonds in the plaster structure. Free radical scavengers trap and deactivate the free radicals before the further reactions leading to polimer degradation.

Free radical Scavengers are activated by the action of light and oxygen and contribute to the self-healing process of polymer bonds inside the plaster structure.

Thanks to free radical scavengers:

  • Polymer bonds are protected
  • Destroyed polymer matrix is regenerate
  • Polymer bonds are strong and the plaster surface is seal

Surface durability

Extended surface durability thanks to improved protection of the polymer bonds against free radical and possibility to regenerate them.

Stability of the colour

Improved colour light fastness and colour stability thanks to pigments' particles protections against UV and free radical.

Wide colour range

Extened coloristic options - 511 Colours of Nature and 36 Intense colours.

OTHER BENEFITS

Double dry technology

The double mechanism ensures that the plaster surface dries very quickly and is resistant to moisture accumulation.

Bioprotect technology

Protection against the development of microorganisms and their destructive effects.
