Superfine 20-30nm with 99.8% Purity Nano Silica Powder

                                   Superfine 20-30nm with 99.8% Purity Nano Silica Powder

Application for nano silica powder:

1. Adding nano-SiO2 to gel coat resin, Mohs hardness increased from 2.2 up to 2.8-2.9 grade, wear resistance is increased 1-2 times, thus generating silica nanoparticles and organic polymer grafting and cooperation with key , make the material toughness increases, so the tensile strength and impact strength increased by more than one times, heat resistance is also greatly improved.

2. Nano-silica surface coated with a layer of organic material, so that it has hydrophobicity, add it to the sealant will soon form a silica structure, namely the formation of nano-silica colloidal inhibit the flow of the network structure, speed up fixed speed, improve bonding effect.

3. Added silica nanoparticles to the composite ceramic substrate, the substrate not only improve the density, toughness and finish, but also significantly lower the sintering temperature.

4. Nano-silica on the surface modification treatment of organic pigments, not only the pigment anti-aging properties increase, but also the brightness, hue and saturation and other indicators were also improved to some extent.

5. Nano-silica light, small particle size, can make plastic becomes more dense, after adding silica into polystyrene plastic film, not only improve its transparency, strength, toughness, and water resistance and anti-aging properties also improved significantly.
