Wetting penetrant WE 3136 is a remarkable chemical additive with several distinct features and applications:

Chemical Composition and Structure:

It is a non-ionic and 100% active block copolymer surfactant. This unique chemical structure endows it with excellent surface-active properties, allowing it to interact effectively with various substances and surfaces.

The block copolymer structure provides WE 3136 with high stability and compatibility in different formulations, making it suitable for a wide range of applications.

Wetting Performance:

It exhibits outstanding wetting ability. It can rapidly spread and uniformly cover the surface of a substrate, significantly reducing the surface tension of the liquid to which it is added. This enables the liquid to penetrate and wet the substrate more thoroughly, which is crucial in many industrial processes such as coating, printing, and adhesion1.

It shows excellent performance in reducing dynamic surface tension. This means that even in situations where the surface characteristics of the material are constantly changing or under dynamic conditions, WE 3136 can maintain a stable and effective wetting effect, ensuring the smooth progress of the process.

Low Foaming Characteristics: One of the significant advantages of WE 3136 is its low foaming tendency. In industrial applications where excessive foaming can cause problems such as interference with the process, inaccurate measurements, or affecting the quality of the final product, this low foaming property is highly beneficial. It allows for a more stable and efficient operation without the need for additional defoaming agents or complex defoaming processes.

Applications:

In the coatings industry, it is widely used as a wetting agent to enhance the wetting and dispersion of coatings on the substrate surface. This leads to improved coating quality, including better adhesion, smoothness, and uniformity of the coating film. It also helps to reduce the consumption of coatings by ensuring their efficient utilization2.

For the printing industry, WE 3136 can improve the wetting and spreading of ink on the printing substrate, resulting in sharper and more vivid printing results. It enhances the stability of the ink system, reducing the risk of ink separation or sedimentation during storage and use.

In adhesive formulations, it can enhance the wetting of the adhesive on the bonding surfaces, thereby increasing the bonding strength and reliability, especially for bonding various materials with different surface properties.
