While emulsions and dispersions have similar characteristics, it is important to understand their differences. An emulsion is a uniform mixture of two immiscible liquids (i.e. oil and water). Oil in water are characterized by things like moisturizers. An example of water in oil emulsion is sunscreen. A dispersion is when small, water-insoluble particles are mixed […]
There are some applications where extremely fine particles are required or the solid content is especially difficult to break down and disperse. These requirements need something besides a dissolver disc and that’s where a bead or basket mill is used. High-speed bead mills are very useful in dispersing otherwise difficult materials. All the steps of […]
If solids, especially pigments, are not broken down into smaller particle sizes and spread evenly throughout the liquid base during the paint manufacturing process, the result is a poor paint quality. This can affect everything from leveling and sagging to color and gloss quality as well as other attributes. Although additives can help with wetting […]
Below are common questions that you should ask to select the right dispermat for your laboratory needs. Does the application require a disperser or mixer? A disperser is required when solid particles are dispersed in a liquid creating a colloidal suspension. If the solid is easily dissolved like sugar in water a simple air or […]
