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 concrete by water and water-borne harmful substances, and significantly enhance the concrete's resistance to freeze-thaw cycles and chloride ion penetration.
Excellent permeability, capable of penetrating deep into the concrete matrix to protect the internal structure from water damage;
Ideal chloride ion penetration resistance, reducing chloride ion penetration by more than 90%;
Reacts chemically with inorganic silicate substrates to form a stable network-like silicone resin structure, ensuring a service life equivalent to that of the protected concrete;
Superior water and alkali resistance: water absorption ratio < 7.5%; after alkali treatment, the water absorption ratio is reduced by 100% (Note: the original text has unclear expressions here, translated based on context logic);
Does not alter the appearance of concrete structures, making it especially suitable for the surface protection of fair-faced concrete;
