Silane coupling agents have two different functional groups, one reacts with organic materials and the other one reacts with inorganic fillers. So inorganic filler are bonded well with organic resins.
Decrease water absorption; the particle size becomes smaller; decrease oil absorption, increase sediment volume. Therefore, silane coupling agents can be used in composite products such as plastics, rubber or paint to improve the processing performance; increase the amount of filler; improve product quality; and reduce energy consumption and production cost. Therefore, silane coupling agents can bring good economic benefits.
