ADD-A40

ADD-A40 can be used as supplied. The neutralizing alkali used in conjunction with the acrylic polymer can significantly impact the properties of the final coating. ADD-A40 releases ammonia during the drying process and therefore has little impact on water and alkaline resistance of the dry film. Use of ADD-A40 should be limited to pH 5 -10.5 and temperatures lower than 700C due to potential loss of volatile ammonia.

Description

ADD-A40

ADD-A40 is an excellent dispersing agent delivering process efficiencies across a range of market applications:

  • Paints
  • Adhesives
  • Ceramics
  • Electronic ceramics

ADD-A40 can be used as supplied. The neutralizing alkali used in conjunction with the acrylic polymer can significantly impact the properties of the final coating. ADD-A40 releases ammonia during the drying process and therefore has little impact on water and alkaline resistance of the dry film. Use of ADD-A40 should be limited to pH 5 -10.5 and temperatures lower than 700C due to potential loss of volatile ammonia.

It is recommended to add the pigment to water containing the dispersing agent with stirring as opposed to
addition of the dispersing agent to a pigment slurry. In general, the pH of the final preparation should be in the region of 8.5 to obtain optimum dispersing efficiency.

Usage 0.5 – 2.0% ADD-A40 into the formulation (based on total pigment weight).

Storage, safety & handling

Although ADD-A40 is freeze stable, it is recommended to store the product at temperatures above 5ºC to enable easy handling of the product. Avoid frost and freezing. Do not store in steel, copper or aluminum containers. Thermal decomposition above 200ºC releases carbon dioxide. ADD-A40 should be handled in accordance with good industrial practice.
