Changfu Chemical's Alcohol-Based Colloidal Silica: An Efficient Filler Solution for Alcohol-Soluble Silicone Resin

In the production and application of alcohol-soluble silicone resins, the choice of filler is crucial. It not only affects the mechanical properties of the silicone resin but also determines its processability and the quality of the final product. Traditional fumed silica, although providing some reinforcement, has a solid content of only 15% in methanol and requires the addition of salt to stabilize the dispersion system. This results in complex operations and increased costs. In contrast, Changfu Chemical's alcohol-based silica sol, with its outstanding performance, offers a new breakthrough for the application of alcohol-soluble silicone resins.

Product Features

Changfu Chemical's alcohol-based silica sol is produced using advanced chemical synthesis technology, which uniformly disperses nano-sized silica particles in alcohol solvents to form a stable colloidal solution. With a regular solid content as high as 30%, it does not require additional stabilizers and can be used directly, significantly simplifying the production process.

Mechanical Property Enhancement

The nano-particles of Changfu Chemical's alcohol-based silica sol have high dispersibility and uniformity, enabling them to form a uniform and dense network structure within the alcohol-soluble silicone resin system. This structure not only enhances the hardness and toughness of the silicone resin but also effectively disperses stress, reducing the occurrence of scratches and wear. Tests have shown that alcohol-soluble silicone resins incorporating Changfu Chemical's alcohol-based silica sol exhibit significantly improved wear and scratch resistance, better withstanding various frictions and impacts in daily use and extending the service life of the products.

Operational Convenience

Compared with traditional fillers, Changfu Chemical's alcohol-based silica sol does not require complex pre-treatment or stabilization operations. Its high solid content allows for more precise control of filler dosage during addition, avoiding product performance fluctuations caused by uneven filler dispersion. Moreover, its good dispersibility enables rapid mixing with other components of the alcohol-soluble silicone resin, forming a uniform composite system and greatly improving production efficiency.
