You can see the effects of additives on BYK YouTube. Suppression and removal of foam in water-based lignosulfonate drilling mud using Big Chem's defoamer. A blender is used to create foam in the water-based drilling mud. When the defoamer is added, the foam disappears (the foam is removed). Even when mixing is started again, no foam is generated (suppression of foam).

A blender is used to create foam in water-based drill mud. The foam disappears with the addition of a defoamer (foam is removed). Even when mixing is started again, no foam is generated (foam suppression).
350ml of water-based lignosulfonate drill mud is placed in the blender container, and the lid is closed. Start at speed 2 and stir for 10 seconds. Foam rises to the surface. Open the lid and add a few drops of the formulation inside. The foam breaks (removal). Close the lid and stir again at speed 2 for 10 seconds. No foam is visible anymore (foam suppression).
The generation of air bubbles is generally undesirable not only in the production of paints, printing inks, and plastic materials but also in many processes. Defoamers and antifoams prevent and remove the occurrence of air bubbles, improving manufacturing processes and achieving excellent surfaces and optimal product characteristics. BYK's defoamers are used in various fields. The main types are: silicone-based defoamers, mineral oil-based defoamers, and polymer-based defoamers.
