Adhesives Sealants Material Hydrophilic Fumed Silica

Feature

Hydrophilic Fumed Silica is a type of material commonly used in adhesives and sealants. It is a fine, white powder composed 

of microscopic particles of amorphous silica. The term "hydrophilic" means that it has an affinity for water, making it highly 

water-absorbent.

In adhesives and sealants, hydrophilic fumed silica is added to improve the rheological properties and overall performance 

of the product. It acts as a Thickening Agent, providing viscosity control and preventing sagging or running of the adhesive or 

sealant. It also enhances the adhesive strength and bonding properties.

One of the main benefits of using hydrophilic fumed silica in adhesives and sealants is its ability to absorb and retain moisture. 

This helps to improve the adhesion to wet or damp surfaces, making it suitable for applications where moisture resistance is 

required. Additionally, the high surface area of the silica particles provides increased surface contact, resulting in improved 

bonding and adhesion.

Hydrophilic fumed silica can be used in a wide range of adhesive and sealant applications, including construction, automotive,

electronics, and consumer goods. It is compatible with various resin systems, such as epoxy, polyurethane, and silicone, 

making it versatile and widely used in the industry.

Overall, hydrophilic fumed silica is a valuable material in the formulation of adhesives and sealants, providing improved 

rheological properties, moisture resistance, and enhanced bonding capabilities.
