SiSiB® PC5430

Tetrapropoxysilane

SiSiB® PC5430, [also called n-Propyl Silicate] is used as a cross-linking agent for silicon rubber, and as a modifying agent for organic and inorganic resins. The ethyl group of ethyl silicate is replaced by the N-propyl group, so the speed of hydrolysis is slower than ethyl silicate. It is equal to Evonik's Dynasil P.

Application


  • SiSiB® PC5430 may be used as an inorganic binder for refractory fillers and pigments, like precision investment castings.


  • SiSiB® PC5430 orthosilicate may be used as a second backup casting coating. It cures faster than colloidal silica system.


  • SiSiB® PC5430 may be hydrolyzed to form silicon dioxide (silica).


  • SiSiB® PC5430 may be used as a binder in zinc-rich (corrosion resistant) coating.



  • SiSiB® PC5430 may be used as a chemical intermediate.


  • SiSiB® PC5430 may be used as a starting material for sol-gel process.


  • SiSiB® PC5430 may be used as as a silane drying agent in sealing compositions.


Packing and Storage


  • SiSiB® PC5430 is supplied in 180Kg steel drum or 900Kg IBC container.


  • In the unopened original container SiSiB® PC5430 has a shelf life of one year in a dry and cool place.
