Silicone Antifoam Agent DCA-3979

Introduction

DCA-3979 is an organosilicon defoamer suitable for both solvent-based and solvent-free systems, offering powerful bubble breaking and foam suppression capabilities. It is highly efficient even at very low dosages and is especially effective in eliminating microbubbles in high-viscosity paint and ink systems.

Physicochemical Data

  • Chemical composition: Fumed silica modified polydimethylsiloxane

  • Appearance: Opaque, cloudy viscous liquid

  • Active content: 100%

  • Solvent: None

Product features

  • DCA-3979 is ideal for solvent-based and solvent-free paint and ink systems with excellent defoaming ability.

  • Particularly suitable for pigment-containing systems; compatibility with varnish systems requires careful evaluation.

  • Exhibits high defoaming efficiency with minimal addition.

Application areas

Applicable in two-component epoxy systems, polyurethane systems, UV-curing coatings, solvent-based or UV-curing screen inks.

Addition Method

Generally, 0.05-1% of the total amount can be added at any stage of production, and after addition, it needs to be stirred as much as possible to achieve good dispersion
