Wacker Wacker® TES 40 WN Silicate
Categories: Ceramic; Oxide; Silicon Oxide

Material Notes: WACKER® TES 40 WN is an ethyl silicate providing approximately 41% silicon dioxide (silica) upon complete hydrolysis.

Properties: WACKER® TES 40 WN contains many hydrolysable ethoxy groups. For applications in which the inorganic SiO2 is to be used as a binder, WACKER® TES 40 WN needs to be activated.

Special features:

  • storage-stable, low-viscous binder with a high silica content (41% SiO2, fully hydrolyzed)
  • liquid source of silica with a high flash point
Application: WACKER® TES 40 WN 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 zinc-rich anti-corrosion paints
  • binder for refractory fillers (production of ceramic shells and cores)
  • precision casting
  • coating material for pigments and fibers
  • liquid source of SiO2 as a (film-forming) binder
  • crosslinking agent, e.g. for silicone elastomers
  • sol-gel processes

Information provided by Wacker Chemie AG.
