Silicon esters are silicon compounds that contain an oxygen bridge from silicon to an organic group, for example, Si-OR. 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.

The tetraalkyl orthosilicates ( also called orthosilicic acid esters) most commonly used as starting materials for sol-gel.
Polysilicic acidesters are condensation products obtained by incomplete hydrolysis or orthosilicic acid esters. They are also be used as starting materials for the sol-gel process.
SiSiB® PC5424 is used to deposit silicic acid formed as aresult 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 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 in cold curing silicone rubber systems.
SiSiB® PC5424 may be used as 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.
