A silane coupling agent has two or more different functional groups in its molecule that play as reactors; generally, one of those chemically bonds with inorganic materials and another one chemically bonds with organic materials. Those respective chemical reactions combine organic and inorganic materials together, therefore eventually improve the adhesion, rheology, and dispersibility of products. Silane coupling agents are widely applied to adhesion, coating, textile, plastic, and surface treatment as they changes the physical properties of the interface between organic and inorganic layers.
