Properties

ROWAFLEX® DF 2
  • is a low-viscous, waterfree antifoam depressant for tenside containing media in aqueous dispersions (Printpastes)
  • prevents foam generation reliably at high shear and air introduction into the media
  • provides control to prevent disagreeable effects such as surface disfunction or separation 
  • is nearly indifferent  and has no influence on the media to be defoamed
  • has good long-term stability
  • has an excellent electrolyte-concentration / stability, eg.
Sodium sulfate                > 200 g/l
Sodium chloride              > 200 g/l
Water glass                    > 200ml/l
Sodium hydroxide 45%  > 160 g/l

Application

ROWAFLEX® DF 2 can be added to print pastes or other polymerdispersions with high viscosity. It can be stirred into the media undiluted.
