All the information provided is in accordance with the present state of our knowledge. Nonetheless, we disclaim any warranty or liability whatsoever and reserve the right, at any time, to effect technical alterations. The information provided, as well as the product's fitness for an intended application, should be checked by the buyer in preliminary trials. Contractual terms and conditions always take precedence. This disclaimer of warranty and liability also applies particularly in foreign countries with respect to third parties' rights.
For high efficiency it is necessary that PULPSIL® 238 C be well dispersed in the foaming medium. Therefore PULPSIL® 238 C can be added only in neat form if high amounts of surfactants and/or high shear forces ensure a good dispersion.
Preferably PULPSIL® 238 C should be added in emulsion form. The use as a booster to organic defoamers is also possible, but sufficient compatibility of PULPSIL® 238 C with the organic system has to be guaranteed.
When used in a suitable formulation like an emulsion, PULPSIL® 238 C is an excellent antifoam agent, especially recommended for the use in different pulp processing steps like washing, screening, bleaching and waste water treatment. The product is thixotropic. Weak stirring is necessary to reduce the viscosity.
