It is not enough to separate the particles, since they can re-agglomerate afterwards. This re-agglomeration is termed flocculation. Flocculation can cause immediate problems with color, or perhaps it won&#8217;t be seen until application such as rolling out a paint in one area and brushing it out in another where there are different shear rates. Rolling\/brushing color differences it&#8217;s called hat banding.<\/p>\n<p>In Figure 1, a light blue paint has been applied to a substrate. Due to poor dispersion or flocculation, when the paint is partially dry, a test for dispersion is the application of shear by a finger in a circular motion (\u201crub-out test\u201d). That energy in a semi-set paint film is sufficient to redistribute the pigment in the medium, resulting in the dark blue area. In addition to the dispersion of pigments, the surfactant displaces the air at the interface of the pigment particle. One of the more difficult materials to disperse has been single-walled carbon nanotubes, due to their morphology, and the strong attraction between the spindle-like particles which possess a high aspect ratio.<\/p>\n<p>Dispersants absorb onto the pigment surface and therefore maintain pigment spacing <strong>by electrostatic repulsion<\/strong> and\/or <strong>steric hindrance<\/strong>. Both stabilization mechanisms are described below.<\/p>\n<p><strong><u>Electrostatic Repulsion<\/u><\/strong><\/p>\n<p>The pigment particles in the liquid paint carry electrical charges on their surfaces. Ideally, through the use of additives, it is possible to make all pigment particles equally charged. Counterions to the pigment-surface ions, concentrate at the pigment surfaces (in the liquid phase) so that an \u201celectrical double layer\u201d is formed (<strong>Figure 3<\/strong>). This is the ideal case and never wholly occurs practically.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"size-medium wp-image-17637 alignleft\" src=\"https:\/\/ulprospector.ul.com\/wp-content\/uploads\/2024\/06\/electricalpigment-300x123.png\" alt=\"\" width=\"300\" height=\"123\" srcset=\"https:\/\/ulprospector.ul.com\/wp-content\/uploads\/2024\/06\/electricalpigment-300x123.png 300w, https:\/\/ulprospector.ul.com\/wp-content\/uploads\/2024\/06\/electricalpigment.png 307w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p><strong>Figure 3<\/strong>. Electrical double layer on pigment surfaces<\/p>\n<p><strong><u>Steric Stabilization\/Hindrance<\/u><\/strong><\/p>\n<p>Dispersing additives, which function by steric hindrance, display two structural features. First, the products contain resin-compatible chains (hydro-carbon units) which, after adsorption of the additive onto the pigment surface, project into the surrounding resin solution. This layer of adsorbed additive molecules with the protruding chains is referred to as steric hindrance or \u201centropic stabilization\u201d (<strong>Figure 4<\/strong>).<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-17638 alignleft\" src=\"https:\/\/ulprospector.ul.com\/wp-content\/uploads\/2024\/06\/pigmentstabilization.png\" alt=\"\" width=\"291\" height=\"119\" \/><\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p><strong>Figure 4.<\/strong> Pigment Stabilization through Steric Stabilization<\/p>\n<p>Second, these materials contain one or more groups that have a strong affinity to attach to the pigment, also known as \u201canchor groups\u201d \u2013 that all together provide a strong, durable adsorption onto the pigment surface.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignleft size-full wp-image-17639\" src=\"https:\/\/ulprospector.ul.com\/wp-content\/uploads\/2024\/06\/Picture5.png\" alt=\"\" width=\"255\" height=\"176\" \/><\/p>\n<p>Steric stabilization occurs in solvent-borne systems and in water-reducible systems which contain solvated resins. Structural features composed of pigment affinic groups (polar) and resin-compatible chains (non-polar), these additives exhibit surface-active properties. Therefore, they not only stabilize the pigment dispersion, but they also function as wetting agents.<\/p>\n<p>The first question to answer when selecting your dispersing agent is whether you need electrostatic or steric repulsion. The answer is highly dependent on the system you formulate: Is it\u00a0solvent-based?\u00a0Water-based?<\/p>\n<p>If your paint medium is a polar (solvent-based paint), the answer is simple. Electrostatic stabilization is impossible. Steric stabilization is the only way.<\/p>\n<p>With a polar medium (water-based and some solvent-based formula),<\/p>\n<ul>\n<li>Electrostatic stabilization is the default way. This is for example the kind of stabilization mechanism that you would find in wall paints.<\/li>\n<li>In the case of more complex systems, steric stabilization can prove useful.<\/li>\n<\/ul>\n<p>Again, dispersing agents are one of the more important additives to a paint system. Take the time to evaluate them and run some simple tests to decide what is the best option for you.<\/p>\n<p>As mentioned earlier related articles are below for further information on dispersants. In addition, most equipment manufacturers of dispersing equipment also have short videos to show how their equipment works, and at the same time show the mechanism of dispersion.<\/p>\n<p><a href=\"https:\/\/ulprospector.ul.com\/3858\/pc-understanding-dispersants\/?utm_source=Knowledge+Center&amp;utm_medium=article&amp;utm_campaign=dispersants_paints_coatings&amp;utm_term=2024pc&amp;utm_content=Hirsch\" target=\"_blank\" rel=\"noopener\">Understanding Dispersants<\/a>, 2016, Marc Hirsch;<\/p>\n<p><a href=\"https:\/\/ulprospector.ul.com\/8805\/pcc-mixing-things-up-formulating-with-dispersants\/?utm_source=Knowledge+Center&amp;utm_medium=article&amp;utm_campaign=dispersants_paints_coatings&amp;utm_term=2024pc&amp;utm_content=Hirsch\" target=\"_blank\" rel=\"noopener\">Mixing Things Up: Formulating with Dispersants<\/a>, 2018, George Deckner &#8211; Cosmetic Dispersants: function, mechanisms, types and formulation tips.<\/p>\n<p><a href=\"https:\/\/ulprospector.ul.com\/12258\/pc-dispersants-the-understood-misunderstood-additive\/?utm_source=Knowledge+Center&amp;utm_medium=article&amp;utm_campaign=dispersants_paints_coatings&amp;utm_term=2024pc&amp;utm_content=Hirsch\" target=\"_blank\" rel=\"noopener\">Dispersants &#8211; The Understood Misunderstood Additive<\/a>, 2021 Marc Hirsch<\/p>\n<p><a href=\"https:\/\/ulprospector.ul.com\/5437\/dispersants-for-steric-stabilisation\/?utm_source=Knowledge+Center&amp;utm_medium=article&amp;utm_campaign=dispersants_paints_coatings&amp;utm_term=2024pc&amp;utm_content=Hirsch\" target=\"_blank\" rel=\"noopener\">Dispersants for Steric Stabilization<\/a>, <a href=\"https:\/\/ulprospector.ul.com\/5293\/pc-dispersants-electrostatic-stabilisation\/?utm_source=Knowledge+Center&amp;utm_medium=article&amp;utm_campaign=dispersants_paints_coatings&amp;utm_term=2024pc&amp;utm_content=Hirsch\" target=\"_blank\" rel=\"noopener\">Dispersants for Electrostatic Stabilisation<\/a> &#8211; Using dispersants for electrostatic stabilization in coating formulations, and <a href=\"https:\/\/ulprospector.ul.com\/10613\/pc-the-differences-between-wetting-agents-and-dispersants\/?utm_source=Knowledge+Center&amp;utm_medium=article&amp;utm_campaign=dispersants_paints_coatings&amp;utm_term=2024pc&amp;utm_content=Hirsch\" target=\"_blank\" rel=\"noopener\">The Differences between Wetting Agents and Dispersants<\/a>, 2020 &#8211; 2022, Jochum Beetsma<\/p>\n<p>There is also a good article in the Paint &amp; Coatings Industry, <a href=\"https:\/\/www.pcimag.com\/articles\/109554-introduction-to-additives-part-4-dispersants?utm_source=Knowledge+Center&amp;utm_medium=article&amp;utm_campaign=dispersants_paints_coatings&amp;utm_term=2024pc&amp;utm_content=Hirsch\" target=\"_blank\" rel=\"noopener\">Introduction to Additives, Part 4: Dispersants<\/a>, 2021-12-14 PCI Magazine<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>This topic has been covered many times over the last eight years and previous articles should be reviewed to better understand the topic.
