SiSiB® PC5430 |
Tetrapropoxysilane (TPOS) . Synonym: Tetrapropyl Orthosilicate; Tetrapropyl Silicate. Countertype of Evonik DYNASIL P |
Chemical Structure |
Introduction |
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. |

Applications |
SiSiB® PC5430 may be used as an inorganic binder for refractory fillers and pigments, like precision investment castings. SiSiB® PC5430 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 starting material for sol-gel process. SiSiB® PC5430 may be used as a crosslinking agent for silicone sealant. SiSiB® PC5430 may be used as a drying agent in sealing compositions. SiSiB® PC5430 may be used as a chemical intermediate. |
