Dodecyltrimethoxysilane Chemical Properties,Usage,Production

Chemical Properties

Colorless to yellowish transparent liquid

Physical properties

This colorless to straw-colored liquid boasts a density of 0.89 g/cm³, a melting point of -40°C, and a boiling point of 125°C. With a flash point of 108°C and a refractive index of 1.4274, it exhibits stability under specific conditions, making it suitable for diverse industrial uses.

Application

One of the standout features of Dodecyltrimethoxysilane is its exceptional hydrophobicity, which makes it an ideal water-repellent agent. When applied through impregnation, it forms a protective hydrophobic layer on surfaces, preventing water infiltration. This property is particularly valuable in construction, where it is used to treat concrete, stone, and other porous materials. By inhibiting moisture penetration, it enhances the durability and weather resistance of structures, protecting them from damage caused by rain, humidity, or freeze-thaw cycles.Beyond construction, its water-repellent capabilities extend to other fields such as automotive and textile industries.
