PIDICRYL 120 V

Pidicryl 120 V is a dispersing agent for water-based paints for dispersions of Pigment and Extenders. It is a dispersing agent used in the manufacture of Premium Emulsion Paints. Its salient features are superior gloss development and high efficiency with inorganic pigments, especially TiO2.

Dispersing agents act by coating the surfaces of inorganic mineral particles with negative charges–through attraction to the positive charges that develop on the particles when the particles come into contact with water. This process is known as ‘adsorption’. The effect of the adsorption of dispersing agent is to produce a net negative charge on the particle surface such that the particles repel each other. This repulsion reduces any tendency of the slurried mineral to flocculate or agglomerate. When a mineral is dispersed in water using dispersing agent, this repulsion reduces the interaction between particles, thus lowering the viscosity of the mineral slurry or paint mill-base. The slurry can then remain fluid until quite a high quantity of the mineral is added (70 – 80% mineral). The slurry also has better flow properties and can remain stable longer with dispersing agent than without it.
