Keep Buildings in the Best Possible Condition

Concrete and stone buildings are not only affected by moisture, cold and UV radiation. Owners are also faced with the growth of algae and moss, as well as with dirt, dust and graffiti. With silanes, owners have a promising agent at hand that keeps building fabric intact and makes facades easy-to-clean. Evonik has developed PROTECTOSIL®, a silane-based product family tailored for construction. It can be added to building materials as an admixture, while the surface of existing buildings can be treated with a spray. The building protection forms a water-repellent yet breathable layer that provides long-lasting protection for the building material and reinforced concrete. Other PROTECTOSIL® products provide facades with a beading effect so that dirt, dust, vegetation and graffiti can be easily removed. PROTECTOSIL®, made for long-lasting protection.
