Nano SiO2 Water-proof Silicon Dioxide Nanoparticles Make Hydrophobic Ultrathin Layer Coating

Nano SiO2 Water-proof Silicon Dioxide Nanoparticles Make Hydrophobic Ultrathin Layer Coating

Product name: hydrophobic silicon dioxide nano powder
Appearance: white powder
Particle size: 10-20nm and 20-30nm
Purity: 99.8%
Specific surface area: 250-260 m2/g

Product Features:

1. Hydrophobic nano silica has the characteristics of small particle size, high purity and large specific surface area. It has good adhesion, thixotropy and suspension stability.

2. Significantly improve the toughness and smoothness of paints and coatings. And the can opening effect also has a significant improvement effect.

3. At the same time, the hydrophobic/oily nano-silica can greatly improve the anti-sagging and construction properties of paints and coatings.

For wear/paint applications:

Nano-silica has good thickening and thixotropy in coatings. The scrubbing resistance has been improved from thousands of times to tens of thousands of times, and the abrasion resistance has been increased by more than 10 times. Oily nano-silica can effectively improve the wetting of the coating film surface of the architectural coating by rainwater and the adhesion of dust, and improve the stain resistance and self-cleaning ability of the coating film. Adding nano-silica to the hydrophobic anti-corrosion coating not only has good adhesion and corrosion resistance, but also has high density and permeability, and has a good waterproof effect. In UV-curable coatings, oily nano-silica can increase the glass transition temperature of the coating film.

Suggested addition amount: 0.5-2% or depending on the actual situation.

Storage: Store in a cool, dry place, away from heat sources.

Packing: double-layer anti-static packaging bag
