Chemical Properties

Silicon dioxide nanoparticles coated with KH570-Silane coupling agent is super oleophilic, and hydrophilic. It is suitable for both oily and waterborne systems.


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.
