I. Definition and Core Ingredients
Silicon waterproofing agent is a new, highly effective waterproofing material based on organosilicon compounds (such as sodium methyl silicate and potassium methyl silicate). The silicon-oxygen bonds (Si-O) in its molecular structure chemically react with hydroxyl groups (-OH) in building materials, forming a dense, hydrophobic film. This film, invisible to the naked eye at nanometer thickness, effectively blocks water penetration while maintaining the material's breathability, preventing internal moisture accumulation.

II. Performance Characteristics: A Balance of High Efficiency and Environmental Protection
Combined Waterproofing and Breathability: Compared to traditional waterproofing materials (such as asphalt and polyurethane), silicone waterproofing agents not only form a waterproof layer but also allow water vapor to pass through, preventing mold or peeling caused by internal moisture remaining trapped. For example, in the preservation of historic buildings, their breathability can prevent cracking in brick and wood structures due to humidity fluctuations. Weather Resistance and Durability: Experiments have shown that high-quality silicone waterproofing agents can last for over 10 years, maintaining stable performance, especially in areas with large temperature fluctuations and strong ultraviolet rays. For example, spray-coated exterior walls of high-rise buildings in coastal areas can provide long-term protection against erosion from sea breezes.
Environmentally Friendly and Safe: This product contains no heavy metals or volatile organic compounds (VOCs), emits no irritating odor during application, and complies with green building standards.
Easy Application: It can be sprayed or brushed directly onto the base surface, eliminating the need for complex processes. It is highly compatible with a variety of substrates, including concrete, mortar, tile, and stone.

III. Applications: Comprehensive Coverage from Construction to Industry
Construction: Widely used for moisture and seepage control on the exterior walls of high-rise buildings, basements, tunnels, and bridges; in the preservation of historic buildings, it prevents salt precipitation, alkali effusion, and weathering.
Industrial: In the wood processing industry, it prevents wood from swelling and deformation due to water absorption; in pool leakage prevention, it protects against water erosion and chemical attack; in oil production, it regulates mud viscosity and prevents well collapse. Special scenarios: Used for moisture-proofing of library and archive rooms, precision instrument rooms, and waterproofing of agricultural irrigation and drainage channels.
