3-Isocyanatopropyltriethoxysilane Usage And Synthesis

Description

3-isocyanatepropyltriethoxysilane is an isocyanate functional silane. It is used for the functionalization of numerous compounds with active hydrogen atoms. It hydrolyzes in the presence of moisture to form silanols, which can react with themselves to produce siloxanes.

3-isocyanatepropyltriethoxysilane is mainly applied in these aspects:

  1. As crosslinkers for one part moisture curable urethane adhesives, sealants and coatings.
  2. As adhesion promoters for one part moisture curable and two part reactive urethane systems.
  3. As adhesion promoters for silicone sealants or coatings, to enhance adhesion to organic substrates with active hydrogen atoms.
  4. It can provide good wet adhesion to glass, metal and other inorganic substrates, and can provide good thermal, chemical and UV stable performance.
  5. It hydrolyzes slower than SiSiB® PC2710, SiSiB® PC2720 is better for applications requring greater open time or enhanced shelf stability.

Chemical Properties

Colorless clear liquid

Hazard

A poison by skin contact. Moderately toxic by inhalation. A mild skin and severe eye irritant.
