Wacker Wacker® TES 28 Silicate
Categories: Ceramic; Oxide; Silicon Oxide

Material Notes: Product description: WACKER® TES 28 is tetraethoxysilane, also known as tetraethyl orthosilicate.

Properties: WACKER® TES 28 is a monomeric silane. It can be hydrolyzed to form silicon dioxide (silica).

Application: WACKER® TES 28 is used for the precipitation of silica upon complete hydrolysis. The SiO2 coating firmly binds inorganic fillers and pigments and adheres well to different inorganic substrates like glass, ceramics or metall. Chemical and mechanical properties of the substrates can be improved by the thin SiO2 film, which is also highly heat-resistant.

  • binder for refractory fillers (production of ceramic shells and cores)
  • precision casting
  • silica coating on pigments, fibers and other surfaces
  • source of finely divided silica
  • crosslinking agent, e.g. for silicone elastomers
  • water scavenger in sealants
  • sol-gel processes
