HYDROPHILIC FUMED SILICA-1
2 year ago
Silica powder is a commonly used additive in adhesives and sealants. It is a fine, white powder that is made from silica,
a compound found in nature as quartz. Silica powder is known for its excellent reinforcing properties, high temperature
resistance, and good adhesion to various surfaces.
Silica powder is a chemical material that is composed of silicon dioxide (SiO2). It is a fine, white powder that is commonly
used in various industries for its unique properties. Silica powder has a high melting point, low thermal expansion, and
excellent electrical insulation properties. It is also chemically inert and has a high hardness, making it suitable for use in
ceramics, glass manufacturing, electronics, and as an abrasive in polishing and grinding applications. Silica powder is also
used as a filler in rubber and plastic products, as a catalyst in chemical reactions, and as a desiccant to absorb moisture.
High Suspension Pure SiO2 Hydrophobic Fumed Silica is a type of silica that has been chemically modified to repel water.
This makes it ideal for use in applications where water repellency is desired, such as in coatings, adhesives, and sealants.
The high suspension properties of this silica make it easy to disperse in a variety of liquid systems, ensuring uniform coverage
and improved performance. Its pure SiO2 composition also makes it highly stable and compatible with a wide range of materials.
Overall, High Suspension Pure SiO2 Hydrophobic Fumed Silica is a versatile and effective additive that can enhance the water
repellency and performance of various products.
