SiSiB® PC5424 is a hydrolyzed and oligomerized form of ethyl silicate. It is a mixture of monomers, dimers, trimers and cyclic polysiloxanes.
SiSiB® PC5424 is a transparent liquid containing 40% silica (SiO2) by mass, but in practice, in addition to chain condensates, it also contains branch-shaped and ring-shaped condensates. It is the equivalent of Momentive's TEOS-40, Wacker's SILICATE TES40, Evonik's Dynasil 40 silane.

Color and Appearance
Colorless transparent liquid.
SiSiB® PC5424 is used to deposit silicic acid formed as a result of complete hydrolysis. The resulting silicic acid bonds well to many inorganic substrates, such as ceramic, fillers, glass, metal, pigments and synthetic fibers. The deposition of a thin SiO2 layer improves the chemical and the thermal stability and mechanical properties.
SiSiB® PC5424 orthosilicate may be used as a binder in zinc-rich (corrosion resistant) coating.
SiSiB® PC5424 may be used as a starting material for sol-gel process.
SiSiB® PC5424 may be used as a crosslinker component for silicone adhesive in cold curing silicone rubber systems.
SiSiB® PC5424 may be used as a hardening component in dentistry for impression materials and as binder for embedding material.
SiSiB® PC5424 may be used as a binder in precision foundry industry.
SiSiB® PC5424 is supplied in 200Kg steel drum or 1000Kg IBC container.
In the unopened original container SiSiB® PC5424 has a shelf life of one year in a dry and cool place.
