3、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.

Limitless silanes

They are used as durable hydrophobing agents in construction, bridge and deck applications. They are also used to hydrophobe inorganic powders to make them free-flowing and dispersible in organic polymers and liquids. Generally, alkoxysilanes are not effective at hydrophobing unfilled plastics.
