1、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.

2、Limitless silanes

Alkoxysilanes with hydrophobic organic groups attached to silicon will impart that same hydrophobic character to a hydrophilic inorganic surface. They are used as durable hydrophobing agents in construction, bridge and deck applications.

3、Silane Coupling Agents

Many conventional coupling agents are frequently used in combination with 10-40% of a non-functional dipodal silane, where the conventional coupling agent provides the appropriate functionality for the application, and the non-functional dipodal silane provides increased durability.

4、Silane Coupling Agent

Any silane coupling agent with three alkoxy groups on silicon should bond equally well to an inorganic substrate, but matching of the organofunctional group on silicon with the polymer type of the resin to be bonded will dictate which silane coupling agent should be used in a particular application.
