Over long-term use, concrete structures are most susceptible to corrosion from moisture, chloride ions, and carbon dioxide, leading to corrosion of rebar and loss of strength. IOTA-550 (3-aminopropyltriethoxysilane) is widely used in concrete protection systems as an impregnating agent or formulation additive. It forms a hydrophobic network of silicon-oxygen bonds within the concrete pores, blocking water penetration. Unlike traditional surface coatings, IOTA-550 does not affect the breathability of concrete and offers long-lasting weather and UV resistance, making it an ideal choice for the maintenance of bridges, tunnels, and highways. With the increasing demand for green buildings and long-life projects, aminosilane products are gaining increasing market attention. Water-based, environmentally friendly protective agents, in particular, are gradually replacing solvent-based products, aligning with the industry's sustainable development goals.
