IOTA 5160 is a difunctional chlorosilane monomer containing two readily hydrolyzable Si–Cl bonds and a chloromethyl (–CH₂Cl) functional group. It serves as a core intermediate for the synthesis of various chloromethyl- or methyl-functional silane coupling agents, widely used in composites, surface treatment, and adhesion promotion.

Key Features

• Dual Functional Groups: Si–Cl bonds can hydrolyze and condense to form siloxane networks; the chloromethyl group can be further derivatized into amino, mercapto, epoxy, and other functional groups.

• High Reactivity: Suitable for multi-step synthesis processes to prepare functionalized silane coupling agents.

• Volatile Transparent Liquid: Facilitates handling and reaction monitoring.

• Strong Derivatization Capability: Enables the preparation of various downstream products through alcoholysis, ammonolysis, Grignard reactions, and more.

Technical Specifications

Main Applications (Silane Coupling Agent Intermediate)

• Synthesis of Chloromethyl Silane Coupling Agents: Used as a raw material for the preparation of chloromethyltrimethoxysilane, chloromethylmethyldimethoxysilane, and others.

• Functional Group Transformation Intermediate: The chloromethyl group can be further converted into amino, mercapto, cyano, epoxy, and other groups to build customized coupling agents.

• Surface Treatment Agent Intermediate: Used to develop interfacial additives that enhance the bonding between inorganic fillers and organic resins.
