Chloropropyltrimethoxysilane Crosile® 202 has various applications, including: 

• Synthesis of octakis(3-chloropropyl)octasilsesquioxane 

• Silanization of nanoparticles such as carbon nanotubes (CNT) and silica nanoparticles (SiO2) for the development of molecularly imprinted polymers for protein detection and fabrication of mesoporous silica (organic-inorganic hybrid) 

• Functionalization of silica-iron oxide nanoparticles, which can be used as catalysts for the synthesis of pyrano(3,2-c:5,6-c')dichromene-6,8-dione derivatives 

• Use as a raw material for preparing Si-69, KH-550, and other silane coupling agents 

• Use as a rubber processing aid to couple inorganic fillers in various halogenated rubber to improve physical and mechanical properties 

• Synthesis of organosilicon compounds containing quaternary ammonium cations, as antifungal and odor-proof finishing agents, with special bactericidal, odor-proof, antistatic, and surface activity 

• Application as a reinforcing agent and crosslink agent for compound material, ink, gluewater, and sealant material. 

3-Chloropropyl trimethoxy silane is insoluble in water and can react with water slowly, but easily triggers hydrolysis cross-linking reaction in an acid or alkaline environment. It also has a good coupling effect with epoxy glass fiber reinforced plastics.
