Description and Uses

(3-Chloropropyl)trimethoxysilane is a silane coupling agent that is commonly used in the field of chemistry. It is a colorless and transparent liquid that has a strong odor. It is used as a coupling agent in the polymer industry to improve the adhesion between two substrates. It is also a starting material for synthesizing various compounds, such as surfactants, organosilanes, and other functional molecules.

(3-Chloropropyl)trimethoxysilane is a good coupling agent for epoxy resins to glass in laminates.
