Trimethoxysilane (CAS NO.2487-90-3) is a vital intermediate of synthetic functional organosilicon compounds. Together with polymers with ethylenic linkage ends, it can generate addition reaction. Under the affect of steam, it can produce Si-OH linkages. Besides, cross-linked polymers will be formed by further self-condensation or condensation together with dialkyl silicone oil. These cross-linked polymers can be used in various fields, such as adhesive, coatings, organosilicon modified polymers, hydrogenation reagents, surface treatment, etc.

Handling and Storage:

Trimethoxysilane should be sealed and stored in cool and well ventilated place away from fire and water.
