Properties In general, the liquid has a certain surface tension, which makes it difficult to disperse and wet on a solid surface. The effect of the wetting agent is to destroy this surface tension and make the liquid easier to wet to the surface of the material to achieve better dispersion and wetting effect. Due to its good dispersion and stability effect, the emulsion synthesis stage can be used as one of the main emulsifiers, which can improve the dispersion stability of the system, and is conducive to control the viscosity and reduce the gel. It is suggested that the added amount is about 0.2%. As a supplementary agent, OT-75 can reduce the surface tension of the emulsion very quickly, and can be used as a wetting agent, osmosis agent, leveling agent, and spreading agent

With, the recommended addition amount is 0.05%~0.2%.

The mechanism of action of the wetting agent mainly involves some intermolecular interactions, including:

1. Adsorption: the charged ions or polar groups in the wetting agent interact with the surface of the medium, thus reducing the liquid-solid surface tension and making the liquid easier to disperse and wet the surface of the material.

2. Dispersion: The non-polar groups in the wetting agent interact with the van der Waals force between the molecules of the medium to disperse the molecules in the liquid, thus increasing the wetting performance of the liquid to the solid surface.

3. Surface expansion: wetting agent molecules gather on the surface and form a molecular film, so as reducing the liquid-gas surface tension, increasing the contact area between liquid and air, making the liquid more likely to disperse and wet the surface of the material.

The mechanism of action of wetting agents is multifaceted, and the wetting effect is achieved by affecting the physical and chemical characteristics of the liquid-solid contact surface. Different wetting agents have different mechanisms of action, so it is necessary to choose the appropriate wetting agent according to the specific situation when wetting the material.

Features (main functions) have a very important role in the actual production and use. The mechanism of action of the wetting agent mainly involves adsorption, dispersion and surface expansion, etc., and the wetting reversal means that the wetting agent affects the wetting performance of the liquid. When wetting the material, it is necessary to choose the suitable wetting agent, and consider the influencing factors such as surface tension and chemical reaction to achieve the best wetting effect.

The application fields of water-based pressure sensitive adhesive include: textile, papermaking, petrochemical, rubber, metal, paint, plastics, cosmetics, cosmetics, agricultural products, industrial and mining, detergent and other processes and formulas.
