Description
Process of preserving the homogeneous and dispersed state of the pigments in the paint. Stabilization is achieved by two basic mechanisms: (a) Pigment interfaces are electrically charged using convenient additives, therefore repulsion force between particles of similar charge keeps the pigments from agglomeration; (b) Polymeric dispersion additives carrying pigment-loving groups prevents the pigments from agglomeration by forming a polymer layer around the pigment particle (: steric hindrance)
