SIOX-5 RE25
Water repellent for natural stone, plaster, terracotta
DESCRIPTION
SIOX-5 RE25 is a water repellent protective coating based on sol-gel technology developed by the Group of Chemistry for Cultural Heritage at the University of Padua, Italy (Patent n. 0001370467 Synthesis of silica protective films by tin-catalized sol-gel process).
HOW IT WORKS
The product contains nanostructured silica gel. Once applied it forms a layer of amorphous silica thin, colorless, transparent, compatible, water resistant and traspirant.
The functionalized component - hydrophobic- is arranged outwards and it prevents the absorption of water and substances by porous surfaces as natural stone or artificial material (plasters, stucco,terracotta).
