Silane Coupling Agent Crosile CPTEO γ-Chloropropyltriethoxysilane
Chemical Properties
Censil CPTMO is γ-Chloropropyltrimethoxysilane.
The product is colorless transparent liquid. It is insoluble in water and can react with water slowly, but easily to trigger hydrolysis cross-linking reaction in the acid or alkaline environment, which is main basic material used in compounding methoxy silane coupling agent. In the mean time, the product has good coupling effect with epoxy glass fiber reinforced plastics, beside which, it can also be applied to compound material, ink, gluewater and sealant material as reinforcing agent and crosslink agent.

Application
Censil CPTMO is the main raw material for preparing Si-69, KH-550 and other silane coupling agents.
Censil CPTMO is also used as a rubber processing aid to couple inorganic fillers in various halogenated rubber to improve various physical and mechanical properties.
Censil CPTMO can also be used to synthesize organosilicon compounds containing quaternary ammonium cations, as antifungal and odor-proof finishing agents, with special bactericidal, odor-proof, antistatic and surface activity.
