Defoamers are chemical formulations with pronounced surface activity, suited to suppress undesired foaming or to destroy foam that has already formed. There is some distinction between defoamers (prevent the formation of foam) and air-release additives (force the bubbles to the surface faster).


In the construction industry, defoamers prevent the undesired foaming of cement-based dry mortars. They are also used in metal processing, detergents and cleaning agents, and waste water treatment. Defoamers and ventilators are used in almost any area of application.
