Application

Tetrapropyl Orthosilicate serves multiple purposes primarily as a versatile inorganic binder for refractory fillers and pigments which is essential in precision investment castings It is often used as a secondary backup casting coating benefiting from a faster curing time compared to colloidal silica systems Tetrapropyl Orthosilicate can be hydrolyzed to produce silicon dioxide making it valuable as an initial material in the sol-gel process It acts as a binder in zinc-rich coatings providing corrosion resistance and also functions as a crosslinking agent for silicone sealants Additionally it is effective as a drying agent in sealing compositions and serves as a useful chemical intermediate
