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 a water in oil emulsion is sunscreen. A dispersion is when small, water insoluble particles […]
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 […]
If solids, especially pigments, are not broken down into smaller particles and spread evenly throughout the liquid base, 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 in the beginning of the dispersion […]
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 electric mixer is ok. What is the particle size needed for the application? If the final particle […]
