Evonik's Protectosil® products maintain uniqueness, functionality and beauty of modern and historical buildings.
The Charlottenburger Tor in Berlin, Germany, has been treated with Protectosil® SH to consolidate the construction material.
Protectosil® SH improves the stability of stones.
Protectosil® SH is used to deposit silicic acid formed as a result of complete hydrolysis. The resulting silicic acid bonds well to many mineral, inorganic substrates, such as natural, brick or terracotta stones. The deposition of a thin SiO2 layer improves chemical and thermal stability as well as mechanical properties.
In the case of porous mineral substrates Protectosil® SH is used for stone consolidation. Depending on the kind of natural stone Protectosil® SH is applied in specifically developed formulations as a silica source.
