hydrophobic nano-silica dioxide

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

The product models of this series are mainly distinguished based on 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 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: As powder flow aids, to improve and maintain the fluidity of materials and prevent material caking.

Coatings, paints and inks: As anti-settling agents and rheological additives, they play roles in thickening, anti-settling and thixotropy, and improve the weather resistance, scratch resistance, surface smoothness and adhesion of coatings.

Adhesives and sealants: They have the functions of thickening, controlling thixotropy, increasing bonding strength and improving sealing performance.

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

Plastic products: Improve their strength, toughness and aging resistance, and increase 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, adsorption and stability, enhance defoaming and antifoaming performance, and improve defoaming efficiency.

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