4、Silane Coupling Agents

What are Silane Coupling Agents? Silane coupling agents are compounds whose molecules contain functional groups that bond with both organic and inorganic materials. A silane coupling agent acts as a sort of intermediary which bonds organic materials to inorganic materials.

Classification and application of silane coupling agents

Silane coupling agents are used in large amounts and come in many varieties, and their structure is usually represented by Y-R-SiX3. Among them, X is a halogen or alkoxy group. Under the action of water, Si-X changes into Si-OH to realize the connection between the inorganic surface and the silane. R is a long-chain alkane,
