HENGDA-E5132 - 3-Chloropropylmethyldiethoxysilane

HENGDA-E5132

3-Chloropropyltriethoxysilane is a chemical compound with the molecular formula (C₂H₅O)₃Si(CH₂)₃Cl. It belongs to the family of organosilanes, which are widely used as coupling agents and surface modifiers in various industrial applications.
Functional Group: Contains a reactive chloropropyl group (CH₂CH₂CH₂Cl) and three ethoxy groups (-OC₂H₅).
Reactivity: Hydrolyzes in the presence of moisture to form silanol groups (Si-OH), which can condense to form strong siloxane bonds (-Si-O-Si-) with surface hydroxyl groups.

  • Chemical Name:

    3-Chloropropylmethyldiethoxysilane

  • CAS No.

    13501-76-3

Applications

  1. Coupling Agent: Like other silanes, it acts as a coupling agent to improve adhesion between organic materials (like polymers) and inorganic substrates (such as glass or metal surfaces).

  2. Surface Modifier: It modifies the surface properties of materials to enhance their compatibility with coatings, adhesives, and sealants.

  3. Adhesives and Sealants: Used in formulations to enhance bonding strength and durability by promoting chemical bonding at interfaces.
