HENGDA-E7033 - Propyltriethoxysilane

HENGDA-E7033

Propyltriethoxysilane is an organosilane compound with the chemical formula C₉H₂₂O₃Si. It consists of a propyl group (C₃H₇) attached to a silicon atom with three ethoxy groups (-OC₂H₅).
Key aspects of propyltriethoxysilane:
Propyl Group (C₃H₇): An alkyl chain that can influence the properties of the compound.
Triethoxysilane Group (-Si(OC₂H₅)₃): Contains three ethoxy groups that are hydrolysable and can form silanol groups for adhesion and bonding.

Applications

1. Propyltriethoxysilane is highly miscible with standard organic solvents, such as alcohols, hydrocarbons and acetone.

2. Propyltriethoxysilane is practically insoluble in neutral water and reacts only slowly to form silanols and higher condensation products.

3. It can be used as water repellent to improve dispersibility of fillers and reduces their sedimentation tendency.

4. Propyltriethoxysilane can be used as an important component for sol-gel coating, silicone resins and silicone rubber.
