Triethoxypropylsilane Usage And Synthesis

Chemical Properties

Colorless liquid

Uses

It is an important material in sol-gel production, it provides a hydrophobic surface treatment for inorganic powders or filter materials and it is one of the catalyst components for polyolefin production with Ziegler-Natta catalyst. It is mainly used as construction waterproofing agent/protective agent, inorganic filler surface treatment agent, and pigment dispersant.

Uses

n-Propyltriethoxysilane was used for surface modification of titania particles and nanotubes. Propyltriethoxysilane may be used as an organosilicon precursor to prepare O₂ sensor platform. They were also used to coat mesoporous silica tablets by the sol-gel technique.

General Description

n-Propyltriethoxysilane (PTES) is a mesoporous hyperbranched organosilane that can be used as a grafting agent. It can be used in the functionalization of a variety of substrates by attaching the silane groups with the surface atoms.

Flammability and Explosibility

Flammable
