Overview

Trimethoxymethylsilane (MTM) is an organosilicon compound that is widely used as a precursor for the preparation of silicon-based materials and is applied in a variety of fields, especially in molecular assembly, nano-synthetic building block connection and selective synthesis of oligosiloxane compounds. It can also be used as a crosslinking agent in the synthesis of polysiloxanes.
Application
Trimethoxymethylsilane can be used for:
As a silica source for the synthesis of synthetic polyethyleneimine-silica (PEI-silica) organic-inorganic hybrid particles.
Converting hydrophilic ceramic surfaces to hydrophobic by modifying -OH groups.
Modifying silica aerogels by inducing hydrophobicity and enhancing mechanical properties without compromising transparency.
