  • What is a dispersing agent?
  • A dispersing agent by definition is a paint ingredient which is used to avoid the flocculation of pigments and fillers. In other words, dispersants promote and stabilize the suspension of solid particles in the paint medium. All dispersing agents have two parts: The choice of your dispersant will greatly influence the quality of your dispersion.
  • How do dispersants work?
  • Dispersants function by reducing the attraction between solid particles like pigments, fillers, or additives in any dispersion. This prevents the solid particles from agglomerating or settling out. Generally, when solid particles are added to any liquid medium, they tend to attract each other due to intramolecular forces.
  • What dispersion agents can be used in water based paint?
  • For use in water-based paints or coatings, anionic charged and non-ionic dispersing agents can be considered. Excellent wetting and dispersion performance in mill-bases for dispersion paints can be achieved using a combination of sodium- or ammonium-polycarboxylate and polymeric non-ionic surfactant additive.
  • What are the benefits of polymeric dispersing agents?
  • Further, polymeric dispersing agents offer several benefits as listed below. Polyacrylic acid-based dispersants are usually lower in molecular weight (and also in cost) in comparison with the other structures. They are particularly recommended in water-based paints to increase the pigment load of inorganic material.
  • How to validate a dispersing agent?
  • To complete its validation, the dispersing agent must follow a serial of laboratory tests as discussed below. Mix the dispersing agent with the system, without pigments. It should be perfectly compatible with the other formulation component. If not, try adjusting the pH or the polarity.
  • How does dispersing agent affect paint properties?
  • The dispersing agent has a significant influence on the paint properties. It has a direct impact on the particle size, and then, its efficiency can be evaluated by checking the right parameters. To complete its validation, the dispersing agent must follow a serial of laboratory tests as discussed below.
