Pre-consolidating agent based on inorganic silica
SIOX-5 RE39 is a pre-consolidant treatment 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 a stable matrix of nanostructured and functionalized silica. Once applied to the material and absorbed by pores, the liquid solidifies forming layers of amorphous silica able to restore the mechanical surface properties of stones, plasters, terracotta.
In contrast to traditional systems based on reactions between ethyl silicate and atmospheric humidity for silica formation (in 30-40 days), the sol-gel technology allows obtaining silica thanks to a neutral catalyst promoting room temperature reactions with a consolidant effect in 24 hours.
