Sedisperse® Particle Dispersion LiquidsProduct Bulletin Number 33 Sedisperse® Particle Dispersion LiquidsDescriptionSedisperse A-, S-, and P-Series liquids are stable, balanced formulations for dispersing insoluble particles. These liquids are basically highly purified, nonpolar, saturated aliphatic hydrocarbons. These liquids produce nearly universal dispersion of powder-liquid systems with solids concentrations below generally three weight percent, but up to as much as five weight percent in some cases. Sedisperse liquids solubilize adsorbed moisture. Sedisperse W-Series liquids are slightly anionic, non-foaming, aqueous formulations for dispersing insoluble particles. They also produce nearly universal dispersion of systems with solids concentrations generally below three weight percent. Applications(Sedisperse liquids contain built-in surfactants so that nothing needs to be added for the dispersion of particles. These liquids are available over a range of densities and viscosities, thus making them applicable to particles of widely varying properties. Sedisperse liquids are designed to be used without dilution or the addition of surfactants, exhibit good shelf life and stability, and are supplied with handling details and density and viscosity data over a temperature range of 24 to 36 deg C. Sedisperse A-Series liquids are the primary liquids and will disperse most powders including metals, oxides, silicates, pigments, Portland cements, propellants and many organic powders. Sedisperse S-Series was specially formulated for dispersion of magnesium oxide and related powders. Those few materials which do not disperse well in Sedisperse A- or S-Series liquids can usually be dispersed in Sedisperse P-Series liquids, which are special formulations, slightly cationic, developed to disperse metal powders (particularly W of Pd), pigmented resin powders, and certain materials (particularly catalysts) determined experimentally. Sedisperse W-Series liquids should be used to disperse those materials which are soluble in the organic Sedisperse liquids. Technical DataRecommended techniques for using these liquids:
where :
(Note: Solvent-resistant tubing, MIC P/N: 500-32906-01, and grooved cell windows, MIC P/N: 500-32806-00 with gaskets, MIC P/N: 500-32804-00 are recommended when using the organic Sedisperse liquids.) Ordering InformationSedisperse Liquids are complete dispersing liquids containing surfactants. A- and S-Series liquids are the ones most widely used for dispersing powders.
Storage RequirementsKeep containers closed. Keep containers from freezing. If container develops a leak during storage, transfer to another clean one. Spillage may be cleaned using detergent and water. Sometimes particles may crystallize and fall out of Sedisperse liquids during storage. This is usually a result of exposure to cold temperatures. It is corrected by warming the Sedisperse to 40 to 50 deg C and then vigorously shaking the liquid in a closed container to re-dissolve the particulates. Material Properties
