Silanes are essential for various industrial and commercial applications. One such silane is Butyl(trimethoxy)silane, also known as n-Butyltrimethoxysilane or 1-butyltrimethoxysilane. It is commonly used as a coupling agent, surface modifier, and adhesion promoter in various industries. In this article, we will discuss the properties, safety data, and applications of Butyl(trimethoxy)silane.

Properties of Butyl(trimethoxy)silane

Butyl(trimethoxy)silane is a colorless liquid with a molecular weight of 196.31 g/mol. It has a boiling point of 172-174°C and a flashpoint of 54°C. It is insoluble in water but soluble in organic solvents such as ethanol, acetone, and toluene. The chemical formula of Butyl(trimethoxy)silane is C7H18O3Si.

Butyl(trimethoxy)silane has a silane group (-SiH3) and a butyl group (-C4H9) attached to the silicon atom. The silane group has a high affinity for various surfaces, while the butyl group provides hydrophobicity and vapor permeability to the compound. The combination of these properties makes Butyl(trimethoxy)silane an excellent adhesion promoter and coupling agent for various applications.

Safety Data of Butyl(trimethoxy)silane

Butyl(trimethoxy)silane is a hazardous substance and should be handled with care. It is highly flammable and can cause severe skin and eye irritation. Ingestion or inhalation of Butyl(trimethoxy)silane can cause respiratory and digestive problems.

It is essential to wear protective clothing, gloves, and eyewear while handling Butyl(trimethoxy)silane. It should be stored in a cool, dry, and well-ventilated area away from sources of heat and ignition. It should also be kept away from incompatible materials, such as strong oxidizers and acids.
