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、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.
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.
