Silane coupling agents contain at least two different reactive groups within their molecules. One of these functional groups forms chemical bonds with inorganic materials, and the other forms chemical bonds with organic materials. This property enables silane coupling agents to function as intermediaries in bonding organic materials to inorganic materials, which normally tend not to bond with each other.


  • Higher-quality composite materials
  • Silane coupling agents improve dispersion during mixing of resins and fillers, and improve the mechanical strength, water and heat resistance, transparency, adhesion and other properties of the composite materials. Silane coupling agents are also highly effective in improving the chemical bonding of heat-cure resins and their compatibility with polymers.

  • Resin modification / Surface treatment
  • Reacting a resin with a silane coupling agent can improve its anchorage to inorganic materials, its room-temperature humidity curing properties, and improve its weatherability and resistance to heat, acids and solvents. Silane coupling agents can also be used to treat the surface of inorganic materials to improve the materials' surface characteristics.
