n-Propyltrimethoxysilane: Guide

n-Propyltrimethoxysilane is a colorless or light yellow transparent liquid. This product involves a process of 3aminopropyltrimethoxysilane, which belongs to the field of fine chemical technology.
By prehydrolyzing 3aminopropyltriethoxysilane under certain conditions, most of the ethoxy in 3aminopropyltriethoxysilane molecule is hydrolyzed into silanol (SiOH), and inhibit the condensation of silanol into siloxane, solving the problem of premature cross-linking of the existing 3aminopropyltriethoxysilane in the aqueous system, and the product prepared by the present invention has the features of strong coupling activity, good stability in storage, and low ethanol content, and can be directly applied in the aqueous system.
The product prepared by this invention has strong coupling activity, good storage stability and low ethanol content, and can be directly applied to glass fiber reinforcement, waterborne polyurethane modification, waterborne coatings viscosity and other waterborne systems.
