Feature
High purity nano powder hydrophobic fumed silica powder is a type of silica powder that has been treated to be hydrophobic,
meaning it repels water. Fumed silica is a fine, white powder that is made by burning silicon tetrachloride in a flame of
hydrogen and oxygen. The resulting particles are very small, with a high surface area, which gives fumed silica unique
properties.
The hydrophobic treatment of fumed silica involves coating the surface of the particles with a hydrophobic substance, such
as a silane or silicone oil. This coating prevents water from wetting the surface of the particles, making them water-repellent.
High purity nano powder hydrophobic fumed silica powder is used in a variety of applications. It is commonly used as a
thickening agent in paints, coatings, and adhesives, where it helps to improve the rheological properties and stability of the
formulations. It can also be used as a r…
