Protectosil® strengthens the masonry
PROTECTOSIL® IMPROVES THE MECHANICAL PROPERTIES AND MAINTAINS FUNCTIONALITY AND BEAUTY OF STONES
Evonik's Protectosil® products maintain uniqueness, functionality and beauty of modern and historical buildings.
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 the 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.
