Introduction:
It is very fine amorphous silicon dioxide made by combustion of high purity silicon tetrachloride with oxygen and hydrogen.
It is fluffy white powder and are used in many kind of coating systems because of its unique property that is fine particle size,
high purity, high transparency, excellent dispersion.
It is used as Matting Agent in Paints and Coatings, like water-based dispersion coatings and topcoats.It generally used for
leather coating for black matt and high transparency.
Silica Matting Agent Hydrophilic Fumed Silica is a type of silica that is used as a matting agent in various industries. It is
hydrophilic, meaning it has an affinity for water and can easily disperse in aqueous systems.
Fumed Silica is produced by burning silicon tetrachloride in a flame of hydrogen and oxygen. The resulting silica particles are
very small, with a high surface area and unique properties. Hydrophilic fumed silica is treated to make it hydrophilic, meaning
it can easily wet and disperse in water-based systems.
As a matting agent, hydrophilic fumed silica is added to coatings, paints, and inks to reduce gloss and create a matte finish.
It works by scattering light and reducing the reflection of light off the surface, giving it a dull appearance. This is especially
useful in applications where a low gloss or matte finish is desired, such as in furniture coatings, automotive coatings, and printing
inks.
In addition to its matting properties, hydrophilic fumed silica also provides other benefits. It can improve the rheological properties
of coatings and inks, enhancing their flow and leveling characteristics. It can also act as a thickening and anti-settling agent,
preventing the settling of pigments and other solid particles in the formulation.
Overall, hydrophilic fumed silica is a versatile and effective matting agent that is widely used in various industries to achieve low
gloss and matte finishes in coatings, paints, and inks.
