Antifoam agent, also known as defoamer, is a chemical additive that reduces the formation of foam in industrial processes related to liquids.
More precisely, defoamers destroy existing foams, but antifoams prevent the formation of more foam.
These compounds are mainly insoluble oils, polydimethylsiloxane, alcohols, stearates and glycol compounds.
Foam formation in industrial processes brings serious problems. For example, it prevents the full filling of storage tanks or causes problems in surface coatings.
Classification of defoamers is as follows:
Oil base, powder, blue base, silicone base, polyethylene glycol, polyacrylic base.
