Product Description

Product Description

Features

Nano-silica added to the coating can improve the scrubbing resistance, strength, hardness and so on. When a small amount of nano-silica 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 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 it 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: hydrophobic anti-corrosion coating, not only has good adhesion, corrosion resistance, but also has dense and ion permeability resistance.

5, transparency: silica can ensure the transparency of nano-modified coatings. High wear-resistant transparent coatings can be prepared by using it, and the wear resistance of the coatings is much higher than before.

6, hardness: when the silica 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 nano-silica can improve the coating

Storage

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