Dynasylan® - the brand for functional silanes
Under the name Dynasylan® SILBOND® we offer more than 15 grades of TEOS-based products.
Ethyl silicate, the common name for tetra ethyl ortho silicate (TEOS), has found worldwide acceptance in applications when a liquid precursor of silica (SiO2) is needed. When properly hydrolyzed, ethyl silicate produces very fine silica particles which can act as a binder to adhere refractories into ceramic shapes or provide corrosion-resistant coatings in combination with zinc dust.
When vaporized and thermally decomposed upon the surfaces of semiconductor chips, ethyl silicate forms electrically insulating layers of silica glass which are necessary in the fabrication of integrated circuits. The chemical applications for ethyl silicate, including cross-linking of silicones, are numerous and constantly being developed. They can be summarized as:
