BYK YouTube Dispersion Stabilization of Carbon-based Particles, Lab Out Test

You can see the effects of additives on BYK YouTube. Dispersion stabilization of carbon-based particles; Comparison of two types of carbon black dispersions (with and without BYK wetting dispersant). Without the wetting dispersant, there is strong aggregation, resulting in large agglomerates and a lack of hiding power. With the wetting dispersant, the fine particles are well de-agglomerated and deflocculated, achieving excellent hiding power and high gloss. Lobout test; When mixing multiple pigments or particles, if the pigments are not sufficiently stable, separation occurs. This issue is referred to as color floatation/color separation, and it can be observed as a color change when performing the lobout test (rubbing the lower part of the paint film with a finger). The pigments are stable with BYK wetting dispersant, and no separation of pigments occurs.
