OSi Holding Limited

Develops, manufactures and sells silicone series fine chemicals. Its product portfolio includes silanes, thermal interface materials, silicone sealants, silicone resins, specialty silicones, silicone emulsions, fluorides and fluorinated products, and other specialty materials. The business supplies silicone raw materials associated with epoxy, polyurethane and UV applications, as well as thermally conductive materials and treated functional fillers. Its materials are used across adhesive and sealant formulations, coatings, waterproof building materials, pigments, agriculture, cosmetics, chemicals and medicine. The company also provides custom silicone product development for requirements not covered by its listed product groups.

The company operates as a private joint-venture holdings group with research and development, manufacturing and sales activities. Its silanes can be used to treat fillers before incorporation into adhesive matrix resins, improving filler compatibility and dispersion while reducing system viscosity. In coating and paint applications, silane additives support adhesion to different substrates and can improve resistance to corrosion, paint-film peeling, scratching and environmental exposure. Functional silanes for building materials can penetrate, cure and bond with inorganic substrates to form protective layers. Thermal interface materials support applications requiring heat transfer, while silicone adhesives and sealants serve industrial bonding and sealing work.
