Polymer dispersion adhesives are milky-white dispersions often based on polyvinyl acetate (PVAc). These dispersions are prepared by emulsion polymerization. Hydrocolloids are long-chain polymers that form viscous dispersions and gels if dispersed in water. Diaspora is the dispersion of a population from their native land, particularly involuntary mass dispersions. It is used as a modifier in the production of anionic Polyurethane dispersions. Zeta potential is a scientific term for electrokinetic potential in colloidal dispersions. Polyester Film, Specialty Chemicals, Inks and Dispersions and Solvent Recovery. The rheology of nanocellulose dispersions has been investigated. The zeta potential is a key indicator of the stability of colloidal dispersions. While it appears similar to sedimentation in colloidal dispersions, the mechanisms are different. It works on any concentrated dispersions without dilution, including foams. Polyethylene waxes are incorporated into inks in the form of dispersions to decrease friction. It is also used to manufacture Polyurethane dispersions (PUDs).. Preservatives are added to products sold as liquid dispersions to retard bacterial growth. For dispersions, this is the equilibrium particle size.
