Why can silicone surface treatment agent improve viscosity?

The main reasons why silicone surface treatment agents can improve viscosity can be summarized as follows:

Activate silicone surface: Silicone treatment agents use special chemical components to activate the silicone surface, making it easier to form chemical bonds with adhesives such as double-sided tape. This activation improves the polarity of the silicone surface, thereby improving the adhesion between the adhesive and the adhesive.

Form a dense protective film: Silicone surface treatment agents form a dense protective film by forming a tight bond with the silicone matrix. This protective film not only enhances the surface adhesion of the silicone material, but also improves its stability, giving it better durability and longer service life.

Improve surface properties: Silicone treatment agents can improve the wettability of the silicone surface, reduce surface energy, increase surface activity and antistatic ability. These improved surface properties help the liquid to be evenly distributed on the silicone surface, thereby improving wettability and adhesion.

Wide applicability: Whether it is a smooth silicone surface or a rough texture, silicone treatment agents can play a powerful role, allowing adhesives such as double-sided tape to adhere tightly to the silicone surface.
Specifically, the mechanism of action of silicone surface treatment agents includes the following aspects:

Improving wettability: silicone treatment agents can make liquids evenly distributed on the solid surface, effectively improving its wettability, thereby enhancing the adhesion performance with the adhesive.

Reducing surface energy: silicone treatment agents have low surface energy, which can effectively reduce the solid surface energy, reduce adhesion, and facilitate fluid flow, but in this context, the reduced surface energy actually helps the adhesive to better fit the silicone surface.

Increasing surface activity: The molecular structure of silicone treatment agents gives them strong surface activity, which can be adsorbed on the solid surface, enhancing their surface activity and further enhancing the bonding force with the adhesive.

Antistatic ability: The surface activity of silicone treatment agents enables them to effectively reduce the generation and accumulation of electrostatic charges, and has excellent antistatic ability, which is particularly important in some application scenarios that require antistatic.

In summary, silicone surface treatment agents significantly improve the viscosity of silicone materials by activating the silicone surface, forming a dense protective film, improving surface properties, and having a wide range of applicability.
