Dfoam AR2

Antifoam for Aqueous Systems

Antifoams are used in many aqueous-based formulations where a build-up of foam may be a problem. Many systems already contain surfactants or dispersing agents which tend to foam to a certain degree. In mechanical or agitated systems foaming can be an issue, so the incorporation of an antifoam during processing will help to significantly reduce the problem.

Dfoam AR2 is designed for aqueous dispersions.

Key Features

  • Powerful Antifoam Properties

  • Silicone Free

  • APE Free

Typical Application Examples

  • Paper Treatment

  • Paints

  • Adhesives

Applications

Dfoam AR2 has been designed for use in all aqueous dispersions such as pigments and inorganic powders. With increased antifoam properties compared to Dfoam AX1, its specifically suitable for lower viscosity systems. Most dispersion preparations are made under agitation, Dfoam AR2 helps to prevent foam build-up during production.
