Application
Dispex® AA 4040 is an ideal dispersing agent for a wide range of water-based coatings. It can be used as supplied and is based on an organic polymer that releases ammonia during the drying process, which minimally impacts water and alkali resistance of the dry film. The use of Dispex® AA 4040 is recommended within a pH range of 5 to 10.5 and temperatures below 70 °C (158 °F) to prevent the loss of volatile ammonia.
Dispex® AA 4140 is the sodium-neutralized version of the same polymer.
Incorporation
- Dispex® AA 4040 should be added under stirring before adding pigments or fillers to the grind.
- For optimal dispersing efficiency, the final preparation pH should be around 8.5.
- The amount of dispersing agent required depends on the pigment's chemical nature, particle surface, and shape, as well as the polymer base of the latex.
- To avoid storage problems, it is recommended to use 1.5 to 2.0 times the determined optimum level of dispersing agent.
Recommended Dosage
- 0.5% to 2% based on total pigment weight.
Benefits
- Effective Dispersion: Improved stability of pigment dispersion and formulated paint.
- Minimal Impact: Releases ammonia during drying, which has little impact on water and alkali resistances of the dry film.
- Versatility: Suitable for a wide range of water-based coatings.
  Summary
  Dispex® AA 4040 is a versatile and highly effective dispersing agent that improves the stability and performance of water-based coatings, especially in the dispersion of inorganic pigments and fillers.
