Product Description

Silane Coupling Agent ELT-S580
Gamma-Mercaptopropyltriethoxysilane 

Description:
Chemical Name: Gamma-Mercaptopropyltriethoxysilane , 3-Mercaptopropyltriethoxysilane
Similar to: KH-580 Silquest A-1891, Z-6910, KBE-803
Formula: HS(CH₂)₃Si(OC₂H₅)₃ 

Structure and Properties:

• Molecular Weight: 238.43 g/mol

• Structure: It consists of a propyl chain with a thiol (mercapto, -SH) group at one end and a triethoxysilane group at the other end.

• Appearance: Typically a clear, colorless to pale yellow liquid.

• Solubility: Soluble in organic solvents like ethanol, acetone, and toluene, but insoluble in water.
   

  Chemical Reactions:

• Hydrolysis: The ethoxy groups can hydrolyze in the presence of water to form silanol groups (-SiOH),
  which can then condense to form siloxane bonds (-Si-O-Si-).

• Thiol-Ene Reaction: The thiol group can participate in thiol-ene click chemistry, allowing for the attachment of various functional groups.

Potential Applications:
This compound is versatile and widely used in materials science, nanotechnology,
and surface chemistry due to its dual functionality (thiol and silane groups).

(1)  Improve the resistance of metal to corrosion, oxidization and adhesion with polymer;
(2)  Used to process carbon white, carbon black, glass fiber, mica;
(3)  Used in anti-shrinking finishing of fabrics.
 

1. Surface Modification: Used to modify the surface of inorganic materials like glass, metals, and ceramics to improve adhesion with organic polymers.

2. Adhesion Promoter: Enhances the bonding between organic and inorganic materials in composites and coatings.

3. Functionalization of Nanoparticles: Often used to functionalize nanoparticles, such as silica or metal oxides, to introduce thiol groups for further chemical reactions.

4. Rubber and Polymer Industry: Acts as a cross-linking agent or coupling agent in rubber and polymer formulations to improve mechanical properties.

5. Bioconjugation: The thiol group can be used to attach biomolecules or other functional groups to surfaces or particles.
