The main function is to disperse the particles that need to be dispersed in the water-based paint on the surface so that they have better stability. Gloss-improving dispersants can improve the gloss of water-based paints, improve the flatness of the surface of water-based paints, and maintain a certain level of stability. In this way, when sunlight hits the wall, the water-based paints will emit good gloss. Increase color transparency and saturation

The main difference between dispersants and surfactants is that dispersants improve the separation of particles in a suspension, while surfactants are substances that reduce the surface tension between two phases of a substance. Dispersants are a form of surfactant. But all surfactants are not dispersants. In addition to acting as dispersants, surfactants can also act as detergents, wetting agents, emulsifiers, and foaming agents. Usually, they are organic compounds.

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.
