www.shinetsusilicone-global.comSilane 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. It is this characteristic that
A Silane Primer: Chemistry and Applications of Alkoxy Silanes
krayden.comranging from 0.05 to 1.00% of the coating.5 Effective coupling action with silanes as additives depends on meeting several criteria: (1) Good mechanical dispersion of the silane into the coating will assure uniform coupling and best efficiency. (2) The solubility parameters and reactivities of the polymer and silane must be compatible.

Silane Coupling Agents
krayden.comSilane Coupling Agents ilane coupling agents are silicon-based chemicals that contain two types of reactivity – inorganic and organic – in the same molecule. A typical general structure is (RO) 3 SiCH 2 CH 2 CH 2-X, where RO is a hydrolyzable group, such as methoxy, ethoxy,
Silane Coupling Agents - Gelest, Inc.
www.gelest.comThe general formula for a silane coupling agent typically shows the two classes of functionality . X is a hydrolyzable group typically alkoxy, acyloxy, halogen or amine . Following hydrolysis, a reactive silanol group is formed, which can condense with other silanol groups, for example, those on
