De-Foaming Agents:De-foaming agents are chemicals that are added to a liquid in order to reduce or eliminate the formation of foam. Foam can be a problem in many industrial processes, as it can cause equipment to malfunction or become clogged. De-foaming agents work by reducing the surface tension of the liquid, which prevents the formation of bubbles. There are many different types of de-foaming agents available, and the most effective one for a particular application will depend on the properties of the liquid being treated.
