DISPEX AA 4140
Dispersant for inorganic pigments and fillers. Dispex AA 4140 is a dispersing agent for the production of water-borne paints and varnishes, especially for dispersions of inorganic pigments.
Appearance: pale yellow liquid.
The product can be used in the form supplied. The alkaline neutralizing agent used in conjunction with the acrylic polymer can greatly affect the properties of the final coating.
Dispex 4140 Sodium Solution often has a slightly negative effect on the dry film properties of the coating.
Dispex AA 4140 is effective in the pH range 5-12 and temperatures up to 100 ° C.
Compared to dispersants for inorganic pigments such as polyphosphates, Dispex AA 4140 is based on an organic polymer and improves the storage stability of both pigment pastes and finished coatings.
There is only a slight effect of high temperature or pH changes.
