HYDROPHILIC FUMED SILICA-2
2 year ago
Silica powder is a commonly used additive in adhesives and sealants. Its appearance is white color powder, is ground
by silicondioxide. Silica powder is known for its excellent reinforcing properties,high temperature resistance and good
adhesion.
Silica powder is made up to silicon atom and oxygen atom.It is wide used in various industries like glass, ceramic and
other electrical industries.
Hydrophilic fumed silica belongs to one of fumed silica. The water affinity of hydrophilic fumed silica can be created by
surface changing technology.It has a high affinity for water after treated.This means it is very easy to
absorb and disperse water molecules.
Hydrophilic fumed silica is often used as thickening agent in various products like paintings,adhesives and cosmetics.
It can effectively enhance the flow and the stability of liquid.
