Fitech Materials,making a real difference
Wholesale Fumed Silica with Nano-Level 99.5% Used for Coatings
Basic information:
Nano-silica added to the coating can improve the scrubbing resistance, strength, hardness and so on. When a small amount of nano-silica (VK-SP30T) is added to the coating, the anti-ultraviolet aging test performance of the coating is greatly improved, the drying time is greatly reduced, and the problems of poor suspension stability, poor thixotropy and low finish of the raw material are also well solved. The coating with nano-silica (VK-SP30T) can opening effect is also significantly improved, the coating is not stratified, anti-current hanging, good construction, greatly improved pollution resistance, and has excellent self-cleaning and adhesion.

Application:
1, wash resistance: wash resistance to tens of thousands of times
2. Weather resistance: Adding a certain amount of VK-SP30T can significantly improve the UV aging resistance of traditional coating products.
3, stain resistance and self-cleaning: research shows that the stain resistance and self-cleaning of the coating film can be improved by the following ways, one is to use the multi-microporous structure of nano silicon oxide, through a certain process means to form a nanoscale geometric complementary (such as convex and concave) interface structure on the surface of the coating film, so that it absorbs air and forms a stable gas barrier film on the surface; The second is the surface treatment of nano silica particles, so that the surface of its biparental or biphobic, effectively improve the rain on the architectural coating surface wetting and dust adhesion, improve the coating stain resistance and self-cleaning ability.
4, hydrophobic corrosion resistance: VK-SP30T hydrophobic anti-corrosion coating, not only has good adhesion, corrosion resistance, but also has dense and ion permeability resistance.
5, transparency: VK-SP30T can ensure the transparency of nano-modified coatings. High wear-resistant transparent coatings can be prepared by using VK-SP30T, and the wear resistance of the coatings is much higher than before.
6, hardness: when the VK-SP30T nanoparticles are uniform in the organic material and a single particle dispersion, the nanoparticles as a rigid chain on the organic material to enhance the effect, thereby improving the hardness of the UV-curable coating film.
7, thermal stability: in UV-curable coatings, Wanjing nano-silica can increase the glass transition temperature of the coating film.
8, viscosity: The addition of VK-SP30T nano-silica can improve the coating
