Dfoam AR2 serves as an effective antifoam agent specifically tailored for aqueous dispersions. In formulations where surfactants or dispersing agents contribute to foam buildup, Dfoam AR2 plays a crucial role in mitigating excessive foaming, particularly in mechanical or agitated systems. Its design addresses the challenges of foam accumulation during processing, providing an efficient solution to significantly minimize such issues in aqueous dispersions.

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, it is specifically suitable for lower-viscosity systems. Most dispersion preparations are made under agitation, Dfoam AR2 helps to prevent foam build-up during production.
Typical addition levels:

  • Paints: 0.2 to 0.5%
  • Adhesives: 0.5 to 1%
  • Pigment dispersions: 0.1 to 0.5%

Typical Application Examples:

  • Paper treatment
  • Paints
  • Adhesives
