Colloidal Silica

Changfu Chemical's colloidal silica products utilize advanced chemical methods to uniformly disperse nano-sized silica particles in various organic solvents, forming stable colloidal solutions. Unlike traditional physical dispersion methods for silica powders (such as high-speed stirring), these products completely avoid particle agglomeration, ensuring that the silica particles are highly dispersed and evenly distributed.

The product series of Changfu Chemical's colloidal silicas have the following significant features:

1.Ultra-fine particles and high specific surface area: The product is colorless and transparent, and will not affect the color of the coated object.

2.High dispersion and excellent properties: It has excellent wear resistance and good light transmittance, significantly enhancing the overall performance of materials.

3.Strong adhesion and film-forming characteristics: When the solvent evaporates, the silica particles firmly adhere to the surface of the object and form a uniform porous gel or dense silica film through siloxane bonding.

4.High purity: The products have extremely high purity, with most impurity contents at the ppb level and some at the ppm level, ensuring the purity of the material.

5.Controllable particle size and morphology: The particle size of silica ranges from 7 to 140 nm, with a narrow particle size distribution. The particle morphology is controllable, and without the addition of surfactants, it can achieve single dispersion, multiple dispersion, and various shapes such as chain-like, peanut-like, hollow, and spherical.

6.High stability: The products have a stability period of over one year in different environments, significantly extending the storage period.

7.Diverse dispersion media: Suitable for a variety of aqueous and non-aqueous solvents, including water, alcohols, esters, ethers, benzenes, ketones, and liquid polymers, meeting the needs of different application scenarios.

With its outstanding product performance and broad application scope, Changfu Chemical is committed to providing high-quality colloidal silica solutions for customers and promoting the technological progress and development of related industries.
