Applications

SiSiB® PC5410E can be used as an inorganic binder for refractory fillers and pigments, like precision investment castings.

SiSiB® PC5410E can be used as non-chlorine or ultra-low chlorine insulation heat resistant material.

SiSiB® PC5410E can be used in the semiconductor industry to produce high quality abrasive particles.

SiSiB® PC5410E can be used as a second backup casting coating. It cures faster than colloidal silica system.

SiSiB® PC5410E can be hydrolyzed to form silicon dioxide (silica).

SiSiB® PC5410E can be used as a binder in zinc-rich (corrosion resistant) coating.

SiSiB® PC5410E can be used as a starting material for sol-gel process.

SiSiB® PC5410E can be used as a crosslinking agent for silicone sealant.

SiSiB® PC5410E can be used as a drying agent in sealing compositions.

SiSiB® PC5410E 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.

Packing and Storage

SiSiB® PC5410E is supplied in 200Kg steel drum.

In the unopened original container SiSiB® PC5410E has a shelf life of one year in a dry and cool place.
