This technology is based on nano-molecular silane materials, providing three-dimensional protection for concrete structures through full immersion. Silane molecules penetrate into the internal pores of concrete and form a permanent protective layer via chemical bonding. It can effectively prevent the erosion of water and water-borne harmful substances on concrete, and significantly enhance the freeze-thaw resistance and chloride ion resistance of concrete.
Excellent permeability: It can penetrate deep into the interior of concrete materials to protect the internal structure of the substrate from water damage;
Ideal chloride ion penetration resistance: It can effectively reduce chloride ion penetration by more than 90%;
It reacts chemically with inorganic silicate substrates to form a stable reticulated silicone resin structure, so its service life is the same as that of the protected concrete;
Excellent water resistance and alkali resistance: Water absorption ratio is less than 7.5%; the water absorption ratio remains 100% after immersion in 0.1mol/L NaOH solution;
It does not change the appearance of concrete structures, making it especially suitable for the surface protection of fair-faced concrete;
