Silicon dioxide Nanopowder KH570 processing
Product Overview
Silicon dioxide surface modification can reduce the surface energy, improve dispersion and increase compatibility with the substrate. Nanosilica surface is rich in silica hydroxyl, modification modification methods, mainly divided into physical modification and chemical modification of two categories. Physical modification is mainly through electrostatic adsorption, coating and coating and other physical effects on the surface of the particle modification; chemical modification that is, through the inorganic particles of silica hydroxyl and the chemical reaction between the modifier, to change the surface structure of the silica particles, to achieve the purpose of surface modification. Chemical modification generally adopts three ways: coupling agent method, surface grafting method and one-step method. γ-Aminopropyltriethoxysilane, also known as KH570, is an organofunctional silane coupling agent. This product is treated by KH570 and has good lipophilicity and hydrophilicity.

Product Features
Enhanced dispersion: KH570 effectively prevents agglomeration of silica nanoparticles and the modified silica nanoparticles have better dispersion.
Improved hydrophobicity: KH570-modified silica nanoparticles have an increased degree of surface lipophilicity, which allows them to perform better in many applications where hydrophobicity is required. This helps to improve their stability and compatibility in organic media.
Enhanced physical properties: The modified SiO2 nanoparticles have a regular morphology, uniform particle size and reduced water absorption, properties that make them more efficient for use in composites.
Application Fields
Composite reinforcement: The addition of KH570-modified nano-SiO2 to glass fibre reinforced plastics (FRP) and thermoset resins significantly improves the mechanical strength and electrical properties of composites.
Transmission Enhancement Film Preparation: KH570-modified SiO2 is used to prepare hydrophilic transmission enhancement films, which have good optical and mechanical properties and are suitable for optical devices and protective coatings.
Improvement of material properties: It can be used to improve the properties of plastics, rubber, coatings and other materials, such as improving strength, toughness, abrasion resistance, weather resistance and so on.
