Fumed silica, also known as fumed silica, is amorphous silica and its surface-modified products produced by hydrolyzing halosilanes in high-temperature flames. It is a white fluffy high-purity nano-organic inorganic Metal oxides are widely used in coatings, adhesives, inks, papermaking, food, cosmetics, chemical mechanical polishing and other fields.
Characteristics of fumed silica:
As a liquid thixotropic agent and thickener, anti-sedimentation, anti-sagging;
Improve the suspension and dispersion of pigment fillers in liquid systems;
Used as a dispersing and grinding aid;
Improve the corrosion resistance of the coating;
Improve powder fluidity and storage stability;
Improve powder charge and charge stability;
Improve water resistance;
Improve the scratch resistance of the paint film;
Improve the vividness of colors;
Fixed special effects;
Improve the physical and mechanical properties of the paint film;
Improve the adhesion and flexibility of the paint film;
Improve the viscoelastic properties and reinforcement of rubber and elastomer;
Defoaming effect in defoamer;
Improve the coating surface hardness and anti-scratch;
Prevent adhesion in films and elastomers;
As an adsorbent and carrier;
For inkjet printing coating;
As an advanced filling of dental materials;
As a catalyst carrier, remarkable thermal insulation, used for low temperature and high temperature insulation.
