Introduction

QX-139 is a structure modified Hydrophobic Fumed Silica

Thickening agents are commonly used in adhesives and sealants to increase their viscosity and improve their performance. 

One popular thickening agent used in these applications is hydrophobic Fumed Silica.
Hydrophobic fumed silica is a fine, white, fluffy powder that is made by burning silicon tetrachloride in a flame of hydrogen 

and oxygen. The resulting silica particles have a high surface area and are coated with hydrophobic materials, such as dimethyldichlorosilane or hexamethyldisilazane. This hydrophobic coating makes the silica particles repel water and enhances 

their thickening properties.
When added to adhesives and sealants, hydrophobic fumed silica forms a three-dimensional network structure. This structure 

increases the viscosity of the formulation, making it easier to apply and reducing sagging or dripping. The thickening effect also 

helps to control the flow of the adhesive or sealant, preventing it from spreading too quickly and ensuring proper coverage.
Thixotropy is another important property of hydrophobic fumed silica. Thixotropy refers to the ability of a material to become less 

viscous when subjected to shear stress, such as when it is stirred or applied. This property allows the adhesive or sealant to flow 

easily during application, ensuring good wetting and adhesion to the substrate. However, once the shear stress is removed, the 

material quickly recovers its original viscosity, preventing it from flowing or sagging over time.
In addition to thickening and thixotropy, hydrophobic fumed silica also offers other benefits in adhesives and sealants. It can 

improve the mechanical properties of the formulation, such as its strength, flexibility, and resistance to deformation. It can also 

enhance the stability and shelf life of the product by preventing settling or separation of the ingredients.

Overall, hydrophobic fumed silica is a versatile and effective thickening agent for adhesives and sealants. Its unique properties 

make it suitable for a wide range of applications, providing improved performance and reliability.
