Phenyltrimethoxysilane Description
Phenyltrimethoxysilane (CAS 2996-92-1), also known as Trimethoxyphenylsilane, is a colorless, low viscosity liquid. It reacts with water to form silanol and methanol. Upon hydrolysis, reactive silanols are formed, which can condense with other silanol groups, such as those on silica or clay fillers, creating siloxane chains. This makes phenyltrimethoxysilane ideal for surface modification and as a coupling agent in a variety of industrial applications.

Phenyltrimethoxysilane: Guide
Phenyltrimethoxysilane (CAS 2996-92-1) is a colorless, low viscosity liquid that contains phenyl and methoxy groups. It is soluble in organic solvents such as alcohols and aromatic hydrocarbons. When hydrolyzed, it forms reactive silanol groups, which can bond with inorganic materials to create strong siloxane chains.
This silane is used in coatings, adhesives, and sealants to improve adhesion, weather resistance, and mechanical properties. It also helps create hydrophobic layers and is widely used in surface treatment and as a coupling agent for various materials.
