Solar Radiation is source of two threats to the facade:
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?
Embrittlement of the plaster
Cracking and blistering
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.
Other plasters after years of exploitation
Ceresit CT 76 after years of exploitation
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.
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
Destroying polimer bonds
Ceresit CT 76 - self healing effect
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
Extended coloristic options - 511 Colours of Nature and 36 Intense colours.
Double dry technology
The double mechanism ensures that the plaster surface dries very quickly and is resistant to moisture accumulation.
Protection against the development of microorganisms and their destructive effects
