| DIMETHYLETHOXYSILANE Usage And Synthesis |
| Chemical Properties | Colorless clear liquid | | Uses | Dimethylethoxysilane (DMES), a volatile liquid, is used by NASA to waterproof the heatprotective silica tiles and blankets on the space shuttle. DMES readily produces a variety of products in the presence of small amounts of moisture or bases. DMES readily produces a variety of products in the presence of small amounts of moisture or bases. | | Application | Will form high-boiling polymeric by-products with aqueous
work-up | | Hazard | An inhalation hazard. Headache, eye and
upper respiratory tract irritant. | | Safety Profile | An inhalation hazard.
Experimental reproductive effects. A
flammable liquid. When heated to
decomposition it emits acrid smoke and
irritating vapors. |
