Dispersing Agents

The stabilization of solids in the liquid phase of the paint can be achieved with the use of dispersing agents.


These additives produce a long-term stable, fine and homogeneous distribution of the inorganic and the organic particles in polar and non polar liquid phases. 


The whole process is called de-flocculation of solid particles and the substances used for this process are high and low molecular surfactants. 


As surfactants are in principle amphiphilic compounds that they have one or more “adhesion groups” which can dock with the solid particle by anionic (electrostatic effect) and/or non anionic (steric effect) and a more-or-less long segment which can be solvated.


This class of additives has a marked effect on a series of different, essential characteristics of the paint formulations. So whenever their full action is achieved, they decrease viscosity, increase colour intensity, prevent flocculation flooding and floating of the solid particles and increase levelling, leading to higher gloss.


Our company has developed dispersing agents for water and solvent born coatings distributed under the trade name DISPORGAN.
