General

  • WACKER SILICATE TES 28 is being used for the precipitation of silica (polymeric SiO2 structures) by complete hydrolysis or thermal decomposition. Ethanol is generated as by-product.
  • The polymeric SiO2 structures firmly bind inorganic fillers and pigments and adhere 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.
Applications
  • Anti-Corrosive Coatings
  • Marine & Protective Coatings
  • Industrial Coatings
  • 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, example for silicone elastomers
  • Water scavenger in sealants
  • Sol-gel processes
