This product is a water-soluble silicone resin solution synthesized by
hydrolysis and condensation of various organosiloxanes, and is alkaline. The
specific functional groups in the molecular structure form a stable chemical
bond with the -OH on the surface of the substrate to modify the substrate. At
the same time, it can also condense to form a nano-hydrophobic structure, so
that the surface of the material produces a super-hydrophobic effect. The
product has high reactivity and strong versatility. It is particularly suitable
for hydrophobic treatment of porous inorganic substrates, reducing water
absorption, while maintaining the original color, breathability and appearance
of the material. The substrate treated with this product has self-cleaning,
anti-fouling, moisture-proof and other functions on the surface, which
effectively improves the beauty of the building and extends the life of the
structure. Suitable for the maintenance and treatment of natural stones such as
granite, marble, sandstone, etc., to prevent the stones from becoming diseased;
impregnation of highly water-absorbent inorganic aggregates: such as perlite
boards, roof tiles, cement bricks, high-rise building light brick facings,
asbestos, inorganic fabrics, thermal insulation materials, etc., to make them
have significant waterproof and moisture-proof effects;
