Dfoam AX1

Antifoam for Aqueous Systems

Quick Links

Dfoam AX1 has been designed for use in water‑based paint and adhesive formulations where foam generation and air entrainment occur during manufacture and application. It is a silicone‑free antifoam that effectively prevents air entrainment, froth, and surface foam by promoting bubble coalescence and rapid foam collapse. Foam control is maintained not only during production but also during subsequent stirring and application.

​

Dfoam AX1 is compatible with a wide range of polymer latices, including acrylic, styrene‑butyl acrylate, styrene‑butadiene, PVC, and vinyl acetate systems. It provides efficient and economical foam control in aqueous formulations without adversely affecting film appearance or system stability.

​

Key Features

​

  • Effective silicone‑free antifoam - Controls air entrainment, froth, and surface foam in water‑based formulations without the risk of silicone‑related surface defects.

  • Efficient foam control during manufacture and application - Promotes bubble coalescence and rapid foam collapse, maintaining foam suppression during processing, stirring, and end‑use application. 

  • Broad latex compatibility - Compatible with a wide range of polymer latices, including acrylic, styrene‑butyl acrylate, styrene‑butadiene, PVC, and vinyl acetate systems.

Applications


Aqueous Systems
- Designed for use in a wide range of aqueous systems where foam generation and air entrainment occur during processing and application.

​

Paints & Coatings
- Specifically developed for water‑based paint and coating formulations to control foam during manufacture, mixing, and application, helping to prevent defects such as pinholing and cratering.

​

Pigment Dispersions
- Used in pigment dispersion processes carried out under agitation to suppress foam formation and reduce entrained air during production.

​

Adhesives
- Suitable for aqueous adhesive formulations to improve processing efficiency and final appearance by reducing foam build‑up.

​

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