Silicon Free Antifoam agent DCA-409

Introduction

DCA-409 is a non-silicone defoamer with broad applicability. It is suitable for improving fluidity in both solvent-based and non-solvent type coatings and exhibits strong defoaming, foam stripping, and bubble-breaking effects. Particularly effective in medium to high polarity resin systems such as polyester, epoxy, UV, PE, etc., it also has good compatibility, does not easily cause shrinkage holes in the system, and is safe to use.

Physicochemical Data

  • Chemical composition:Ethylene copolymer

  • Appearance: Colorless to light yellow viscous liquid

  • Active content: 100%

  • Solvent: None

Product features

  • DCA-409 can solve the problem of defoaming in high-viscosity systems, possesses anti-explosion foam properties, can inhibit the introduction of bubbles during stirring, and helps release microbubbles from the coating.

  • DCA-409 is particularly suitable for medium to high polarity resin systems, balancing compatibility with defoaming strength.

Application areas

DCA-409 is used in various solvent-based medium to high polarity resin systems.

  • Unsaturated polyester systems
