nano-sized SiO2 particles for anti-corrosion hydrophobic coatings

Factoy direct offer, small particle size, high purity, quailty and stable production ability. More than 10 years experience in nanoparticles material manfuacture and export. 

pPoduct Details

SiO2, 20-30nm, 99.8%, hydrophobic / hydrophilic both available 


A novel coating material that uses nano-sized SiO2 particles to intensify hydrophobicity and corrosion protection properties


Hybrid SiO2 nanocomposite coatings were fabricated on mild steel.
Highest coating resistance were exhibited by coatings with 3 wt.% SiO2 nanoparticles.
Long-term stability measurement, together with hydrophobic surface measurements, were obtained.

The influence of SiO2 nanoparticles on hydrophobicity and the corrosion protection capabilities of hybrid acrylic-silicone polymeric matrix have been investigated.  A coating with 3 wt.% SiO2, AS 3, demonstrates significant improvement in corrosion resistance with the highest measured CA of 97.3°. Morphology and topography studies clarify the influence of nano-sized SiO2 fillers on the surface topography and demonstrated the uniform and good distribution of the embedded SiO2 nanoparticles within the polymeric matrix.


Above applicaiton part are out of a research for your reference only, also we have customers order SiO2 from us for paintings, but details is not realeased. Applicatino would always needs your own testing, your understanding is highly appreciated, thanks.
