Protective consolidant based on ethyl silicate, siloxane oligomers and additives in an inert solvent mixture.

The particular solvents allow an optimal absorption of the active principle through the capillaries of the stone material until the healthy core of the stone is reached. Here, following a chemical reaction with atmospheric humidity, it turns into silica gel which, subsequently, acts as a binder of the incompact material without giving rise to saline by-products.

The siloxane component performs an important water-repellent action, as well as the bridge function between calcareous molecules and ethyl silicate. BIO R-IPC 30 does not change the breathability of the substrate and does not decrease the permeability to water vapor, does not change the chromatic aspect of the treated materials and has a high resistance to UV rays.
