Stone Hardener with Protectosil^® SH

Protectosil^® SH is a mixture of ethyl esters of different polysilicic acids for the consolidation of construction material.

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 stone, brick or terracotta stones. The deposition of a thin SiO₂ layer improves the chemical and thermal stability and 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 used in specifically developed formulations as a silica source.
