Hydrophobic-Modified Dispersants of “Macromer” Brand for Water-Dispersion Paints

An important stage in the production of paint and varnish materials is the optimization of the process of dispersion of pigments and fillers. It is for this purpose that the V. S. Lebedev Makromer LLC manufactures and offers polycarboxylate dispersants used in the production of water-dispersion paints.

In this paper, the effect of dispersants structure on their efficiency was studied. Based on what was studied, it was found that all the presented samples are highly effective, have electrosteric action, which in turn affects the rheological properties of paints.

The paper analyzes the study of the dependence of paste viscosity on the concentration of dispersants. Due to the double mechanism of stabilization, the rheological properties of paint and its stability are less sensitive to the concentration of dispersants, which facilitates the task of formulators.

Macromer dispersants find application in the production of paint and varnish materials, where they can be used in a wide variety of paint formulations with the introduction of new segments that improve the main indicators of their properties.
