Diaminosilane oligomers

Diaminosilane oligomers are oligomeric silane coupling agents pre-polymerized by hydrolysis of diaminosilane, appearing as pale yellow transparent viscous liquid. The molecules are rich in amino active groups and hydrolyzable siloxane structures. Compared with monomeric silane, it features lower volatility and better storage stability, with excellent wettability on inorganic substrates. It can significantly improve the bonding strength between fillers, substrates and organic resins, suitable for water-based systems with less small molecule precipitation.
