Typical Physical Properties *
process. StarSil™ PD 383 is mainly applied to pulp washing and screening processes but is also effective during bleaching and in effluent treatment.
StarSil™ PD 383 can also be used as a formulation base in Textile dyeing due to its free rinsing properties. StarSil™ PD 383 rinses cleaner and does not have a detrimental effect on lightfastness. StarSil™ PD 383 is extremely shear-stable, even at very low liquor ratios.
StarSil™ PD 383 is dilution stable with proper back thickening. StarSil™ PD 383 can be used undiluted. However, to achieve better dispersion a dilution is recommended. We recommend a pre-dilution of 1:1 to 1:3 in cold water. The diluted emulsion, however, should be processed within a few days.
- Alcogum 1370 (acrylic)
- Cekol 30 (carboxymethyl cellulose)
- Kelzan S (xantham Gum)
Target Viscosity of Dilution should be in the following range (final viscosity is always dependent on the application and handling of the end-use product):
- 800 to 5000 centipoise
It is always recommended that you make your thickened water solution and then add the StarSil™ PD 50 to this solution (or vice versa).
