MSDS Information

TETRAISOPROPYL ORTHOSILICATE Usage And Synthesis

Applications	Tetraisopropoxysilane, the iso-propyl ester of orthosilicic acid, is a colorless clear liquid. It has the following application: As an inorganic binder for refactory fillers and pigments, like precision investment castings. As a second backup casting coating. It cures faster than silica system. May be hydrolyzed to form silicon dioxide (silica). As a binder in zinc-rich (corrosion resistant) coating. As a starting material for sol-gel process. As a crosslinking agent for silicone sealant. As a drying agent in sealing compositions. As a chemical intermediate.
Chemical Properties	Colorless transparent liquid
Uses	it is impurity of Calcitonin . Calcitonin (salmon) (C144555), is a 32-amino acid linear polypeptide hormone that is produced in thyroid in humans. It acts to reduce blood calcium (Ca2+), opposing the effects of parathyroid hormone (PTH).
