What are the effects of dispersants on liquid and solid coatings, respectively?

At present, coatings are needed in decoration, and for the coatings chosen by everyone, certain additives need to be added, and dispersants are one of them. Dispersant is a type of surfactant, and its effect on colorants is also indispensable. What are the functions of dispersants for liquid or solid coatings commonly used in the market? Next, the editor of Jianyi Chemical will introduce it to everyone!

Liquid coatings have strong adhesion and color, and can easily adhere to any object. During the transportation, storage, or use of coatings, certain particles may become detached, affecting the final effectiveness of the application. To ensure strong color and stability of the coating during use, an appropriate amount of dispersant is often added to the coating. Its main task is to rearrange the dispersed solid particles to ensure good stability of the coating and improve the dispersibility of the material.

For solid fuels, adding dispersants during grinding can help with particle crushing and the stability of the particles after crushing. If an appropriate amount of dispersant is added to an oily liquid, it can decompose into many small particles under continuous stirring. After the coating stops stirring, it will quickly separate under the action of external forces, but adding dispersants will form an emulsion. Dispersants in coatings mainly disperse inorganic substances that are difficult to dissolve in liquids, while also preventing solid particles from settling or aggregating, thus forming a stable dispersion system.
