What are the applications of Application
3-(Triethoxysilyl)propionitrile is an ethoxylated silicate that has been used as a coating for aluminum and quartz
General Description
3-(Triethoxysilyl)propionitrile (TESPN) is an organosilyl sol gel that can be used as a silane based coupling agent to improve the adhesion between metal-polymeric composite. It is non-toxic and cost efficient which makes it a suitable alternative to the existing chromate treatment of metals. It can be used in surface modification of silica based surfaces.
