Nano Silicon Dioxide SiO2 liquid CAS 14808-60-7

What are SiO2 Nanoparticles?

Nano Silicon Dioxide SiO2 Nano-silica Particle is a white or transparent liquid with good chemical stability. Nano Silicon Dioxide SiO2 Nano-silica Particle has the characteristics of small particle size, many micropores, large specific surface area, high hydroxyl content on the surface, and strong reflection ability of ultraviolet, visible, and infrared rays. Especially with the improvement of the surface treatment technology of the product, the soft agglomeration degree of nanoparticles is obviously reduced, and the compatibility with organic polymer materials is good, which greatly expands the application field of the product. 

Nano silica has uniform particle size distribution and good stability. Has a large specific surface area and adsorption, good adhesion and good high-temperature resistance, water resistance, and wear resistance. In addition, nano silicon dioxide has electronic and electrical properties, which can greatly improve the material properties.

Applications of Silicon Dioxide liquid SiO2 liquid:

Nano Silicon Dioxide SiO2 Nano-silica Particle is mainly used in silicone rubber, building sealant, coating, electronics and power, aerospace, medicine, and medical materials, resin processing, printing ink, pesticides, and other industries. 

1. Can be applied to rubber products. As a reinforcing agent and anti-aging agent, nano-silica can be used in rubber products to improve strength, toughness, anti-aging, anti-friction fire, prolong life, and other functions. The mechanical strength of pure rubber is very low. When the nano-silica reinforcing filler is mixed, the microcrystalline area with silica as the crystal core is formed, which increases the physical cross-linking point and is more prone to crystallization. The strength of rubber can be significantly improved. It can be seen that the use of nano-silica filler plays an important role in the final performance of silicone rubber.

2. When used in epoxy resin, it can improve tensile strength, impact strength, elongation at break, thermal stability, and other properties of epoxy resin, and maintain transparency. 

3. Can be applied in coatings. Nano-silica can improve the scrubbing resistance, strength, and hardness of the coating. By adding a small amount of nano silica into the coating, the anti-uv aging test performance of the coating is improved more, the drying time is greatly reduced, and the problems of poor suspension stability, poor thixotropy, and low finish of the raw material are solved well.
