Products Description
Isooctyl triethoxysilane is an organic silane impregnation material used for enhancing the durability of concrete, typically available in paste or liquid form. Primarily applied for the long-term protection of concrete structures, it possesses hydrophobic and waterproof characteristics. By penetrating into the concrete substrate to a depth of 2–10 mm, it undergoes hydrolysis and condensation reactions to form a network-like hydrophobic membrane. This significantly improves the concrete's water resistance and resistance to chloride ion penetration. Its molecular formula is C₁₄H₃₂O₃Si.

Applications:
Isooctyl triethoxysilane is widely used across various industries, including paints, coatings, additives, wetting agents, electrical insulation, rubber synthesis, organic coatings, construction materials, and water treatment agents.
Notably, it is also employed in the corrosion protection of concrete structures. It effectively prevents deterioration caused by water ingress, sunlight, acid rain, and seawater, which can lead to corrosion, loosening, spalling, and mold growth in concrete and its embedded steel reinforcement. This significantly extends the service life of buildings.
Additionally, isooctyl triethoxysilane can be used in the production of specialized coatings to improve freeze-thaw resistance, reduce beading (anti-globulization), and minimize fine particle formation.
