Silicone Free Defoamer DCA-441

Introduction

DCA-441 is a non-silicone defoamer suitable for both solvent-based and solvent-free coatings, offering significant improvement in flow properties and exhibiting strong foam suppression, defoaming, and bubble-breaking effects. It is particularly effective in high-viscosity coating systems. DCA-441 also has good compatibility within systems, not prone to causing shrinkage holes, ensuring safe usability.

Physicochemical Data

  • Chemical composition: Acrylic ester copolymer

  • Appearance: Light yellow viscous liquid

  • Active content: 100%

  • Solvent: None

Product features

  • DCA-441 enhances coating flowability and film smoothness.

  • Tackles defoaming challenges in high-viscosity systems, reducing bubble incorporation during mixing.

  • Suitable for thick coating applications, overcoming foaming and pinholing issues for a smooth film surface.

  • Optimizes compatibility and safety in coating systems.

Application areas

Applicable in a variety of systems including two-component PU, amino baking paint, nitro dipping, acid-cured amino, epoxy, both in solvent-based and solvent-free formulations.
