PULPSIL® 672 E is a low to medium viscous, highly effective silicone antifoam emulsion, especially for the use in pulp mills.


PULPSIL® 672 E is characterised by:


  • very good long-term efficiency
  • very good knock-down efficiency
  • excellent drainability
  • free of organic emulsifiers

In general we recommend stirring the emulsion before use (approx. 3 minutes with a propeller stirrer at 200 – 400 rpm). But be cautious: too high shear can break the emulsion.


PULPSIL® 672 E can be dosed undiluted, as it is already sufficiently dispersed by its emulsion form.


If the use of PULPSIL® 672 E should be necessary in diluted form, we recommend using dilutions with solutions made of polyacrylates-based thickener-Systems.

PULPSIL® 672 E acts primarily as an antifoam agent and drainage aid and may be added at various stages during the manufacturing process.


PULPSIL® 672 E is mainly applied to pulp - washing and screening processes, but is also effective during bleaching and in waste water treatment.


PULPSIL® 672 E should be applied in process steps, where high defoaming power and strong drainage performance are necessary.


The 'Best use before end' date of each batch is shown on the product label. Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
