Wetting and dispersing agents are actually a type of dispersant. They have a wetting effect, and this wetting effect mainly acts on the pigment particles, reducing the surface energy of the pigment particles and reducing the intermolecular force. In this …

The dispersion process of pigments in paint is generally measured using a his method determines the coarsest pigment particles present in the pigment dispersion. Different coating products have different fineness indicators that they should achieve.

In coating formulas, many powder fillers are needed to improve the performance of various aspects of the coating and effectively reduce costs. However, since various fillers are inorganic powders, the particle size is relatively small, the specific surface area is large, and the force between particles is relatively strong. , easy to agglomerate, so it is necessary to use appropriate dispersants for different coating formulas to achieve the maximum effect.
