Innovative Silicone Supplier Introduces The Use Strategy Of Wetting And Dispersing Agent

Update:2021-05-28 00:00

Wetting usually refers to the spread of liquid on a solid surface. It is more of reducing surface tension, which is a short-lived process. Dispersion refers to the mechanical process in which the pigment particles dissociate from each other. In paint production, it means that the pigment and filler particles after entering the water phase system stably exist in the water phase in the form of small particles, uniformly distributed, and no longer re-aggregate, which is a long time process.

Generally, wetting agents are substances that can make solid materials more easily wetted by water. By reducing its surface tension or interfacial tension, the water can spread on the surface of the solid material or penetrate the surface, thereby wetting the solid material.

Wetting agents and dispersing agents both play a role in dispersing pigments. The combination of the two can play a synergistic effect so that the pigment and filler particles can be stably dispersed in the coating in a more delicate form.

Innovative Silicone Supplier introduces the appearance of the wetting and dispersing agent as a clear yellow liquid, mainly used in water-based coatings and printing inks. The characteristics of the wetting and dispersing agent are as follows:

1. Excellent wetting and dispersing ability for inorganic pigments, such as iron oxide and titanium dioxide;

2. Improve color intensity;

3. Pigment storage stability;

4. Enhance the compatibility of water-based resin and emulsion in an alkaline medium;

5. Good water resistance;

6. Does not contain alkylphenol ethoxylates;

7. No solvent.
