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.

Needs editing
Format: Kindle
Cute storyline and promising characters, but the lack of editing is painful to read. I would love to read an edited version.

ABSOLUTELY A MUST for Omegaverse Girls!!!
I ABSOLUTELY LOVE Jillian West and her books!!! I’m so happy I already bought book two and now I have to buy the others for the Assurance Security series!! Not gonna lie Val kind of annoyed me at the beginning but she grew on me!! Her men are chef’s kisses!!! Holt annoys me some but I can let it slide. I already bought part two so I’m going to be reading that in between work phone calls!!!! DON’T TELL MY BOSS 😂😂😂😂

Baby bumps and bodyguards
Format: Kindle
Dark, emotional, and unexpectedly tender, Not Ready is an omegaverse romance that delivers found family feels, fierce protectiveness, and a very pregnant heroine who refuses to break. Vale’s on the run from a stalker, but lands in the arms of three private security alphas, cue the swoony tension, fake marriage twist, and slow-burn heat. It’s a little gritty, a little soft, and a whole lot addictive. If you love protective alphas, high stakes, and heroines with quiet strength, this one’s a must-read.

Strong Omegaverse Comfort and a Attention Grabbing Plot
Format: Kindle
Jillian West never misses when it comes to Omegaverse, and Not Ready is no exception. This story was the perfect blend of cozy comfort and emotional depth while still delivering a strong plot. Vale is such a powerful heroine, she is strong, capable, and determined but I love that she still allows her pack to love and take care of her. It’s that balance of independence and vulnerability that makes her so relatable. The relationship dynamics were amazing: Bishop is steadfast and completely head over heels, Mercy is skeptical but protective in his own way, and Holt is the hesitant one whose slow fall is so satisfying to watch unfold. The romance hits that sweet spot between insta-love and cautious build, keeping me hooked the entire way through. And that ending. Oh my god, the cliffhanger! I need the next book in this duet immediately.

Interesting
Format: Kindle
So I will say I enjoyed the story, for sure had its moments where it dragged but it was a great story. I really liked that omegas picked their alphas/make the pack. Normally the Alphas make it and the omega fits in with them which is great but I enjoyed this new version where all the power basically went to the omega. It was a nice change of pace. I can admit some of the weird bedroom stuff with her being pregnant was odd, it’s really not hard to do stuff when pregnant (I know I’ve had two and it’s normal and even encouraged at the end especially if you want the baby out). But I like the story as a whole and will read the second, I do hope the next one isn’t dragged bc it stopped being action or tense after she met her alphas and I don’t think it was brought up or properly done when they tried to do it. More sweet after she left.
