Description:
Nano SiO2 silica has strong adsorption, good plasticity, anti-ultraviolet, anti-aging, chemical resistance and other chemical properties. Non-toxic, tasteless and pollution-free.
In epoxy resin
1. Heat resistance: due to the large specific surface area of the nano-silica particles, the strong interface adhesion with the epoxy matrix, it absorbs a large amount of impact energy, and also increases the rigidity of the matrix, so the nano-silica is within a certain range The particles toughen the epoxy resin and also improve the heat resistance of the material.
2. Toughening effect: Due to the addition of nano silica particles, the impact strength, tensile strength, elongation and other properties of the epoxy composite have been greatly improved within a certain range, indicating that nano silica is toughened The particles played a role. It highlights the excellent filling performance of nano-scale silica, and the material properties have been greatly improved.
Nano SiO2 is used for (silicone) rubber, it can play a very good reinforcing effect in plastics; it can be used for suspension, rheology, reinforcement, anti-aging and dispersion in coatings, inks and other products.
For antibacterial carrier:
It can be used as a carrier in the preparation of fungicides. Applying the nano antibacterial powder to the enamel glaze can produce a washing machine that can effectively prevent mildew and antibacterial. If the nano antibacterial powder is mixed with the interior wall paint, it can have a long-term antibacterial and anti-mildew effect. The times are advancing, and people’s health awareness continues to increase. Therefore, nano-antibacterial powder will be increasingly developed in industries such as medical and health, building materials, home appliances, chemical fibers, and plastic products.
Storage Condition:
Hydrophobic Silicon Dioxide Nanoparticles should be stored in sealed, avoid light, dry place. Room temperature storage is ok.
