Silicon esters are silicon compounds that contain an oxygen bridge from silicon to an organic group, for example, Si-OR. SiSiB® PC5410, the methyl ester of orthosilicic acid, is a colorless, low-viscosity liquid. It is industrially the most important of the tetraalkyl silicates.

SiSiB® PC5410 can be used as an inorganic binder for refractory fillers and pigments, like precision investment castings.
SiSiB® PC5410 can be used as a second backup casting coating. It cures faster than colloidal silica system.
SiSiB® PC5410 can be hydrolyzed to form silicon dioxide (silica).
SiSiB® PC5410 can be used as a binder in zinc-rich (corrosion resistant) coating.
SiSiB® PC5410 can be used as a starting material for sol-gel process.
SiSiB® PC5410 can be used as a crosslinking agent for silicone sealant.
SiSiB® PC5410 can be used as a drying agent in sealing compositions.
SiSiB® PC5410 can be used as a chemical intermediate.
Compared to ethyl silicate, SiSiB® PC5411 has a higher silica concentration which brings cost advantages, but methyl alcohol is generated in the usage environment, so measures are necessary to counteract this.
