Di-T-Butoxydiacetoxysilane, also known as Evonik Degussa Dynasylan BDAC or Degussa Dynasylan BDAC, is a versatile silane coupling agent that offers unique properties and applications in various industries. It is produced by Ningbo Inno Pharmchem Co., Ltd., a leading manufacturer and supplier of high-quality specialty chemicals.

Properties of Di-T-Butoxydiacetoxysilane

Di-T-Butoxydiacetoxysilane is a clear, colorless liquid with a molecular weight of 356.5 g/mol and a boiling point of 150-153°C. It has a density of 1.09 g/cm³ at 20°C and a refractive index of 1.427 at 20°C. Its chemical formula is C14H26O6Si, and its CAS number is 35880-43-2.

As a silane coupling agent, Di-T-Butoxydiacetoxysilane contains two functional groups – an acetoxysilyl and a tert-butoxy group – that enable it to bond chemically to both organic and inorganic surfaces. The acetoxysilyl group reacts with hydroxyl groups on the surface of substrates, while the tert-butoxy group hydrolyzes in the presence of moisture to form a strong siloxane bond.
