3-Chloropropyltrimethoxysilane Usage And Synthesis

Description

(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.

Chemical Properties

Colorless transparent liquid

Uses

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

Uses

(3-Chloropropyl)trimethoxysilane may be used in the synthesis of octakis(3-chloropropyl)octasilsesquioxane.{35}

General Description

(3-Chloropropyl)trimethoxysilane (CPTMS) is an organo-silane which forms a self-assembled monolayer (SAMs) that facilitates the surface modification of different bio-and nano- materials.

Hazard

A poison by ingestion and skin contact.
