Chemical Properties:
Silicon dioxide nanoparticles coated with a KH570-silane coupling agent exhibit strong oleophilic and hydrophilic characteristics. They are suitable for both oil-based and waterborne systems.
Applications:
Silicon dioxide nanoparticle is used as additive for plastics, rubber, ceramics, porcelain, glass, adhesives, fibers, and many other products. It is added to concrete and construction composites as strengthening filler. It has also applications in biomedical field such as drug delivery and theranostics. Silicon dioxide is also used in environmental pro tection products. Silane KH-570 coupling agent is used to improve physical and chemical properties of glass reinforced and mineral filled resins, and reinforced thermoplastic polymers.
