Long-lasting protective layer for surface protection

Evonik solutions for surface protection:

  • water-repellent effect

  • easy-to-clean facades

  • protection against graffiti attacks

  • lower maintenance and repair costs 

Weather influences are major challenges for all kinds of buildings. Be it concrete, brick or natural stone, the structure of these mineral substrates offers suitable points of impact for moisture, wind and UV radiation. Penetrating moisture in particular damages the building substance together with the pollutants dissolved in it (e.g. salts). On top, facades are exposed to dirt, dust or microorganisms such as algae, mold or moss. Evonik offers reliable silane-based solutions against all these damaging influences with its PROTECTOSIL® brand. The different products are available as additives and formulations for construction chemicals as well as agents for surface treatment. Once applied, PROTECTOSIL® provides facades with a highly effective and long-lasting protective layer.

Hydrophic protective layer 
The hydrophobization products of the PROTECTOSIL® range provide a water-repellent effect but do not restrict the breathability of the construction material. By this, the agent reduces damages caused by moisture and frost. Thanks to the long-lasting and life-extending effect of PROTECTOSIL®, maintenance and repair costs are significantly reduced. Hence it contributes to sustainability in the construction sector.

Easy-to-clean facades 
Another product group of PROTECTOSIL® was developed to make cleaning facades extremely effortless. Once applied it provides an extensive beading effect which ensures that dirt, dust or even graffiti cannot stick to the surface. Beyond that, algae, mould and moss can be easily removed from the surfaces treated. No matter which product group of PROTECTOSIL® is used: buildings retain their original look and feel in either way.
