Wetting penetrant WE 3694 is a remarkable chemical additive with several important characteristics and applications:

Properties:

Chemical Nature: It is a non-ionic wetting agent. Non-ionic surfactants are known for their stability and compatibility in a wide range of formulations, making WE 3694 suitable for various applications.

Wetting Performance: It exhibits excellent wetting properties. This means it can rapidly spread across a substrate's surface, reducing the surface tension and ensuring thorough and uniform coverage. This is crucial in coatings, inks, and other formulations where good wetting is essential for optimal performance.

Emulsification Ability: WE 3694 also has good emulsification properties. It can help to mix and stabilize immiscible substances, such as oil and water, in a single formulation. This is beneficial in applications where multiple components need to be combined and remain stable.

Low Foaming: One of its notable features is low foaming. Excessive foam can cause problems in industrial processes, such as interfering with application, affecting the accuracy of dosing, and creating difficulties in quality control. The low foaming characteristic of WE 3694 allows for smooth and efficient operation.

Physical Properties: It has a density of approximately 0.96 g/cm³ (as per DIN 51757 at 23 °C), a dropping point of around 16 °C (as per DIN 51801), and a surface tension of about 27 mN/m when measured at a concentration of 1 g/L at 23 °C.

Applications:

Coatings Industry: In the coatings sector, it is widely used in architectural coatings, industrial coatings, and transportation coatings. It can improve the leveling of the coating, enhance the adhesion to the substrate, and reduce the occurrence of surface defects such as craters and pinholes, resulting in a smoother and more uniform coating film.

Inks and Printing: In the printing industry, WE 3694 is used in ink formulations to improve the wetting of the ink on the printing substrate, leading to sharper and more vivid printing results. It can also enhance the stability of the ink and improve its transfer efficiency.

Other Applications: Due to its excellent wetting and emulsification properties, it can be used in various other applications such as in the formulation of adhesives, detergents, and emulsions where good wetting and stability are required.

Overall, wetting penetrant WE 3694 is a valuable additive that offers excellent wetting, emulsification, and low foaming properties, making it suitable for a wide range of industrial applications.
