2、Limitless silanes

Silane coupling agents are silicon-based chemicals that contain two types of reactivity – inorganic and organic in the same molecule.

3、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.

4、Silane Coupling Agents

The general order of thermal stability for silane coupling agents is depicted.Most commercial silane coupling agents have organic functionality separated from the silicon atom by three carbon atoms and are referred to as gamma-substituted silanes.

Silane Coupling Agent

There are three basic approaches for using silane coupling agents. The silane can be used to treat the surface of the inorganic materials before mixing with the organic resin or it can be added directly to the organic resin or holistic mixing (in organic-inorganic mixture).
