Dispex is an incredibly efficient polyacrylate dispersant which is used to disperse inorganic materials that are found in waterborne automotive and decorative paints, adhesives and construction materials. 


Where Dispex dispersants are used
Dispex acrylic chemistry dispersants that use an ionic repulsion mechanism to disperse the inorganic minerals that are typically used in waterborne paints, coating systems, adhesives  and construction materials - minerals such as calcium carbonate, titanium dioxide and talc.


What makes Dispex unique
Dispex polyacrylate dispersants are exceptionally efficient additives. Efficiency that delivers such a thinning effect that the lowest possible viscosity mill-base is achieved, this means that an even higher solids mill-base is possible, thus delivering a better grind, hence, higher opacity paints and coatings.

Peak performance delivered by Dispex dispersants
Dispex polyacrylic dispersants, whether as pure polyacrylic acid (PAA) or modified with alkylacrylates to deliver higher gloss or water-resistance (hydrophobicity), offer the highest dispersion efficiency i.e. the lowest dosage for the highest solids loading, which in turn enables the best grinding to deliver the best opacity.


DISPEX AA 4140
DISPEX AA 4140 is a derivative of a family of highly effective, low viscosity dispersing agents for water-borne coating systems. The product is especially suited for the dispersion 
of inorganic pigments. DISPEX AA 4140 is a solution of a sodium salt of an acrylic polymer in water.
This straw colored liquid is effective over a pH range 5-12 and up to temperatures in excess of 100°C.

Dispex AA 4140 (formerly Dispex N40) is a derivative of a family of highly effective, low viscosity dispersing agents for water-borne coating systems. 
Compared with inorganic dispersing agents, e.g. polyphosphate products, the organic polymer based Dispex N40 provides improved storage stability of both the pigment dispersion and the formulated paint. There is little or no adverse reaction to high temperatures or pH changes.

Application
Dispex AA 4140 is an ideal dispersing agent for a wide range ofwater-based coatings. It can be used as supplied. 
The neutralizing alkali used in conjunction with the acrylic polymer can significantly impact the properties of the final coating. The sodiumbased Dispex 4140 often contributes slightly negatively to the dry-film coating properties.
Dispex AA 4140 is effective over a pH range of 5 – 12 and up to temperatures in excess of 100 °C (212 °F). 
Dispex AA 4140 is based on an organic polymer and provides improved storage stability of both pigment dispersion and formulated paint when compared with inorganic dispersing agents, e.g., polyphosphate products. 
There is little or no adverse reaction to high temperatures or pH changes as indicated in the graphs below incorporation As opposed to adding the dispersing agent to a pigment slurry, the pigment should be added to heavily stirred water to which the dispersing agent had been added. 
In general, the pH of the final preparation should be in the region of 8.5 to obtain optimum  dispersing efficiency.
The optimum amount of dispersing agent required to form a stable dispersion strongly depends on the pigment’s chemical nature, the particle surface and shape. 
The polymer base of the latex also plays a very important part in the stability equation. In general, significant overdosing may deteriorate the coating’s properties (e.g., water resistance) and generate an economic disadvantage. 

Likewise, insufficient dispersing agent will lead to instability on storage. 
When handling this product, please comply with the advice and information given in the safety data sheet and observe protective and workplace hygiene measures adequate for handling  chemicals.

As with other dispersing agents and because of the batch-to-batch variations of a specific pigment or latex type, the formulator should use 1.5 – 2.0 times the determined optimum level of dispersing agent.
