Nano-Silica For Printing Powder Coating 5-40nm 99.8% Rubber Plastic Silica

Nano-silica (VK-SR01) as a reinforcing agent and anti-aging agent is applied to rubber products, which can improve the strength of rubber products, improve toughness, anti-aging, anti-friction fire, prolong life and other functions.

Nano-silica is the reinforcing filler of RTV silicone rubber, which can improve its strength. On the one hand, it is due to the small size effect and large specific surface area of nano dioxide particles. On the other hand, because its surface contains a lot of silicon light groups, the particles can form a network structure through the action of hydrogen bonding and van der Waals forces, while the silica particles will also have a strong interaction with polysiloxane molecules, improving the interface condition. The reinforcing effect of nano-silica on silicone rubber is affected by its particle size, specific surface area and structure, generally the smaller the particle size, the larger the specific surface area, the higher the structure, the better the reinforcing effect, and the higher the strength and hardness of vulcanized rubber.

Storage

Nano silica should be stored in a dry, airtight environment, not exposed to volatile substances.
