Properties

• Appearance: Colorless transparent liquid
• Acidic, hydrolyzes in contact with water
• Density (ρ): 1.355–1.365 g/cm³

Applications

1. Silane Coupling Agent

   Key raw material for synthesizing silane coupling agents such as KH-550, Si69, widely used in rubber products and glass fiber reinforced materials.
2. Organosilicon Compounds

• Produces γ-chloropropyl alkoxysilane via alcoholysis, used to prepare a series of silane coupling agents.
• Can be co-hydrolyzed with other chlorosilanes to produce silsesquioxane or TQ resin.
• Used as a capping agent for block-modified silicone polymers.

3. Other Applications
   Widely used in adhesives, sealants, water repellents, resins and coatings. Also used as an organic synthesis raw material for preparing other organosilicon compounds and polymers.
