synthetic amorphous silica,
amorphous precipitated silica
Precipitated Silicon Dioxide CAS No.: 7631-86-9 as White Powder Used For Coating Industry
The production of precipitated silica starts with the reaction of an alkaline silicate solution with a mineral acid. Sulfuric acid and sodium silicatesolutions are added simultaneously with agitation to water. Precipitation is carried out under alkaline conditions. The choice of agitation, duration of precipitation, the addition rate of reactants, their temperature and concentration, and pH can vary the properties of the silica.
1, Excellent gloss and viscosity stability.
2, Consistent gloss over varying coating weights.
3, Greater flexibility when you add the silica.
4, Better weathering.
