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 (KH550) is a colourless, transparent liquid with good solubility in water and organic solvents.KH550 is used to improve the surface properties of silica nanoparticles by converting them from hydrophilic to hydrophobic, thereby improving their dispersion and stability in various applications.

Product Features


 

Enhanced hydrophobicity: The surface lipophilicity of the silica nanoparticles is significantly increased by the KH550 modification, which allows them to perform better in many applications where hydrophobicity is required. 

Improved dispersion: KH550 effectively prevents agglomeration of the silica nanoparticles and improves the dispersion of the material, which is essential for improving the overall performance of the composite. 

Improved mechanical properties: The modified silica nanoparticles show better dispersion and stability in the composite material, which enhances the mechanical strength and durability of the material. 

Stability and electrical insulation properties: KH550-modified silica nanoparticles maintain stable properties at high temperatures and also have excellent electrical insulation properties due to their hydrophobicity, which gives them a wide range of applications in the electronics field.

Application Fields

Oil-water separation: KH550 modified nano-SiO2/PU composite membrane is used for oil-water separation, showing efficient separation effect. 

Polymer composites: In plastics, rubber and other polymer materials, it is used as reinforcing filler to improve the mechanical properties, thermal stability and wear resistance of the materials. For example, it is used to manufacture high-strength engineering plastic parts, or to improve the tear resistance of rubber. 

Paints and coatings: Improve the adhesion, weatherability and corrosion resistance of paints. For example, in automotive coatings, to enhance the bonding between the coating and the metal substrate, and to extend the service life of the coating. 

Adhesives: Improve the bonding strength and durability of adhesives. In structural adhesives, to ensure that the bonded joints can still maintain good performance in harsh environments. 

Electronic materials: used in the preparation of electronic packaging materials to improve their thermal conductivity and electrical insulation properties.

A MUST HAVE for my remote as I always drop or loose my remote! Easer to hold too!
Color: Glow Green, Color: Glow Green
I'm on my 2nd or 3rd Apple TV and the remotes stink for me as its like my home office / bedroom eats my remote. The apple remote is also very small and hard for me to hold in my hand and will just slip out of my hand an "poof" gone! However this remote cover is the ticket! I no longer drop my remote but if I do loose it, this bright color glow in the dark is easy to spot! Just like all glow in the dark stuff it must be "charged" under light to glow and is limited how long it will glow. I charged it under a desk lamp before I took the included picture. However, even if it looses its glow charge the fluorescent green / yellow color is easer to spot on a dark floor or under a dark bed or sofa and is easy to spot when using a flash light too if its no longer glowing, the color stands out to the eye in a dark room. This product truly transforms that slick hard to hold and hard to use and impossible to find Apple remote into something I now enjoy using! This is a MUST HAVE PRODUCT if you have a Apple TV! Great stuff at a GREAT price! A TRUE MUST HAVE!

Love it more than expected
Color: Glow Green, Color: Glow Green
I rarely review stuff but I LOVE this case. It makes the remote feel very nice, especially the texture at the back. Yes, it’s true that it’s not exactly like the photo with a cut out for the Siri button but it isn’t an issue. The grip it provides makes me feel luxury. The glow in the dark isn’t very reliable but if “charged” it does work. Definitely recommend.
