Dfoam AR2

Dfoam AR2 is a silicone‑free defoaming and air‑release additive designed for use in water‑based formulations. It is effective in controlling both surface foam and entrained air generated during manufacturing, processing, and application. Dfoam AR2 helps promote rapid foam collapse and improved air release, contributing to smoother film formation and enhanced finish quality.

​

In aqueous systems, Dfoam AR2 supports improved processing efficiency by reducing foam‑related defects such as cratering, pinholing, and micro‑foam. It is suitable for use across a range of applications where effective foam control is required without negatively impacting formulation stability or surface appearance.

Key Features

​

• Effective defoaming and air release - Controls both surface foam and entrained air during manufacturing, processing, and application of water‑based systems.

• Silicone‑free formulation - Provides efficient foam control without the risk of surface defects associated with silicone‑based defoamers.

• Improves film appearance and processing efficiency - Helps reduce defects such as pinholing, cratering, and micro‑foam, supporting smooth film formation and consistent finish quality.

​

Applications

​

Aqueous Dispersions
- Designed for use in a wide range of aqueous dispersions, including pigment slurries and inorganic powder dispersions, where effective foam control is required during processing.

​

Pigment Dispersions
- Particularly suitable for pigment dispersions produced under high agitation, helping to prevent foam build‑up and entrained air in low‑viscosity systems.

​

Paints & Coatings
- Used in water‑based paint and coating formulations to control foam generation during manufacture, mixing, and application.

​

Adhesives
- Suitable for aqueous adhesive formulations to reduce foam and improve processing efficiency and final appearance.

​

Paper Treatment
- Applied in paper treatment processes where foam suppression is required in aqueous systems.

​

Dfoam AR2 has been designed for use in all aqueous dispersions, including pigment and inorganic powder systems. With increased antifoam performance compared to Dfoam AX1, it is particularly suitable for lower‑viscosity formulations. As most dispersion preparations are carried out under agitation, Dfoam AR2 helps to effectively prevent foam build‑up during production.
