Butyltrimethoxysilane (CAS 1067-57-8), a prominent organosilane, possesses a unique set of chemical and physical properties that underpin its wide-ranging industrial utility. As a key product offered by NINGBO INNO PHARMCHEM CO.,LTD., understanding these characteristics is vital for harnessing its full potential as a coupling agent and surface modifier.

Chemically, butyltrimethoxysilane is characterized by a silicon atom bonded to a butyl group and three methoxy groups. Its molecular formula is C7H18O3Si, with a molecular weight of approximately 178.30 g/mol. The three methoxy groups are susceptible to hydrolysis in the presence of water, forming reactive silanol groups (-Si-OH). These silanol groups can then undergo condensation reactions, either with other silanols to form siloxane bonds (-Si-O-Si-) or with hydroxyl groups on the surface of inorganic substrates. This reactivity is the foundation of its function as a coupling agent, creating durable linkages between organic and inorganic materials.

Physically, butyltrimethoxysilane is described as a clear to straw-colored liquid. Its density is typically around 0.896 g/cm³, and it has a boiling point of approximately 164°C. The flash point is around 43.1°C, indicating that it is a flammable liquid and requires appropriate handling and storage precautions. Its refractive index is about 1.3979. The purity of industrial-grade butyltrimethoxysilane is generally high, often exceeding 97.0%, which is critical for consistent performance in demanding applications. This commitment to quality is a hallmark of NINGBO INNO PHARMCHEM CO.,LTD.

The combination of chemical reactivity and specific physical properties makes butyltrimethoxysilane an excellent choice for various applications. Its ability to modify surfaces, enhance adhesion, and act as a crosslinking agent in polymer systems is a direct result of its molecular structure and reactive functional groups. Whether used in coatings, adhesives, composites, or specialized industrial fluids, these properties ensure its efficacy.
