Foam Control Agents
What are antifoams?
Antifoams are additives that prevent foam from forming. Antifoams stop foam interference, damage, and allow peak performance. Silicones and polypropylene glycols are effective options as antifoams. Dow’s antifoams help prevent foam in crop protection, food processing, water treatment, and more.
For many applications and industries, foam isn’t just a nuisance, it’s a problem. Silicone antifoams and polyglycol foam control agents can help solve all of these challenges efficiently and effectively.
Types of antifoams
Silicones are especially effective for foam control – both as antifoams that prevent foam from forming, and as defoamers that react to foam and help minimize it. Silicone foam control products are available as fluids, emulsions, compounds and powders to meet many different applications.
Polypropylene glycols (PPGs) and EO/PO copolymers are also effective foam control agents because of their low foam characteristics and inverse water solubility. These products are available in liquid form, with different molecular weights and viscosities to meet diverse needs.
Although every foaming situation is unique, silicone and polyglycol foam control solutions are trusted for their proven performance as processing aids, defoamers, foam preventers and deaeration materials in various industries, including:
What is the difference between a defoamer and an antifoam?
Dow sells “antifoam” as most of our actives can be used as defoamer (collapsing existing foam, process aid) and also as antifoam (avoid and control the foam formation, formulation aid).
