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.

Beautiful and trendy especially with minor adjustments!
Color: Red, Color: Red
The satin fabric of the bag is of great quality. Thick and resistant to snags. I partied all night with it and it held up beautifully. The color saturation of the red was perfect and against my dark dress was a perfect pop of dramatic color contrast. Notes: The magnetic closure is strong but doesn't form a complete closure because there are only two magnets. Don't turn the bag upside down or small items can fall out. There was a strong chemically smell that dissipated after a week of airing out and adding a few drops of perfume to a tissue that I kept inside the bag. I wanted a "dumpling" clutch so I altered it slightly. First I colored over the gold closure with nail polish to match the fabric color. There is something about the gold tone that detracted from the elegance. Then I added a stitch to the bottom and top corners to round the shape a bit. See pics I can hardly sew on buttons so if I could do it, anyone can! The fabric is well lined and has just enough structure to it to hold the dumpling effect without becoming too slouchy looking. The chain is nice with more elegant looking clasps than other similarly priced bags, but I didn’t use it because I wanted a clutch. Under my arm or in my hand as a clutch this was light and comfortable. Got lots of compliments and questions about where I got it. Overall a fantastic buy.

Roomy, Quality and Versatile
Color: Navy
Very nice quality and appearance. Large enough for wallet, phone, etc. Easily converted from clutch to shoulder purse with removable chain. Handle trim and chain are gold color. Wish it silver but very pleased overall and feel it is a good value.

Beautiful clutch... but chain is defective
Color: Navy, Color: Navy
This is a really beautiful clutch and the size inside is perfect for your necessities. (lip balm, hand sanitizer, pocket tissues, husbands inhaler, hand cream) I really loved that about it however, the chain which is the only option to not holding it all night is terrible. I bought this clutch for a gala but the chain got stuck on my dress just the first time I tried it on. I wish there was another option so I don't have to hold it all night. The chain is really bad quality. It will shred my lace dress. Also the chain is super long. Like too long to actually wear on on side. Or it would fall off all the time. I am 5'9 and this chain to super long for me. You would have to wear it as a cross body- and that does not look nice with formal attire. Returning.
