‍Fumed Silica: A Versatile Additive for Multiple Industries

Fumed silica is a highly functional additive that enhances the mechanical and chemical properties of various materials. Its applications are wide-ranging, from polymer composite materials and silicon rubber to coatings, electronic packaging, gel batteries, ceramics, plastics, sealants, and papermaking.

Fumed silica can improve properties such as reinforcing, thickening, thixotropy, flatting, anti-settling, and anti-sagging. It plays a crucial role in a variety of sectors, enhancing the performance of materials in numerous applications.

Applications of Fumed Silica:

Coatings & Paints

Fumed silica is essential in coatings and paints for rheological control, preventing sedimentation and delamination of pigments. It enhances the weatherability, scratch resistance, and bonding strength between coatings and substrates.

• Wall coatings: Fumed silica prevents paint from flowing down, improves wall surface smoothness, and enhances scratch resistance and exterior durability.
• Floor paints: It improves weather resistance, scratch resistance, and leveling performance, resulting in a higher-quality finish.

Printing Inks

In thermal printing ink, hydrophilic fumed silica accelerates the drying process and prevents smudging and blurring caused by wet ink. In normal printing ink, hydrophobic fumed silica prevents water absorption and reduces foam. For gravure and flexographic printing, fumed silica acts as an anti-settling agent, controlling ink volume for cleaner, sharper prints. It also serves as a dispersion agent and volume control agent in printer cartridges.

Sealants & Adhesives

Fumed silica plays a crucial role in the rheological control of sealants and adhesives, enhancing viscosity and preventing sagging during the curing process. When added to adhesives and sealants, fumed silica forms a network of silica agglomerates, which increases viscosity. Upon shear thinning, the silica network breaks down, allowing for smoother application, but restores once shear is removed, ensuring the product maintains its consistency during curing.

Thermal Insulation Materials

Thanks to its unique manufacturing process and three-dimensional structure, fumed silica features small primary particle size, large specific surface area, high porosity, and excellent thermal stability. These characteristics contribute to the low heat conductivity of thermal insulation materials, making them highly effective at providing insulation in various applications.
