Highly hydrophobic nano silicon dioxide SiO₂

Hydrophobic nano-silica has high hydrophobicity and lipophilicity, and exhibits good dispersibility and compatibility in oily and hydrophobic systems. It has excellent properties such as reinforcement, thickening and thixotropy, anti-settling, matting, flow aid and anti-caking.

Specifications and Models

Note:

The product models of this series are mainly distinguished by different modifiers and surface modification processes, as well as different product characteristics and application fields. Customization is available for special requirements.

Product Features

Unique chemical surface modification endows it with high hydrophobicity and lipophilicity;

Small agglomeration, good dispersibility and uniform particle size distribution;

Low moisture absorption, high free fluidity and good transparency;

Low impurity content, non-toxic, odorless and pollution-free;

Strict production control ensures stable product quality between batches.

Application Fields

Powder coatings and plastic powders: used as powder flow aids to improve and maintain material fluidity and prevent material caking.

Coatings, paints and inks: used as anti-settling agents and rheological additives to achieve thickening, anti-settling and thixotropy effects, and improve the weather resistance, scratch resistance, surface smoothness and adhesion of coatings.

Adhesives and sealants: can thicken the product, control thixotropy, increase bonding strength and improve sealing performance.

Dry powder fire extinguishing agent: as the main hydrophobic component, it reduces the moisture absorption and anti-caking performance of the powder, maintains high free fluidity, and enhances its storage and spraying performance.

Plastic products: can improve the strength, toughness and aging resistance, and increase the elongation and cantilever beam impact strength.

Resins and silicone elastomers: can improve their strength, surface smoothness, wear resistance and aging resistance, and effectively control rheology.

Defoamers: have excellent dispersibility, adsorptivity and stability, enhance defoaming and antifoaming performance, and improve defoaming efficiency.

Hydrophobic nano-silica can also be used in cosmetics, anti-adhesion agents for films, coating additives for anti-glare films and other fields.
