Dispersions, Resins and Additives

Defoamers

Foamaster^®, FoamStar^® and Efka^® defoamers for water-based, solvent-based, and solvent-free formulations

Formulators rely on BASF defoamer technologies to meet the most demanding standards of excellence – such as those in automotive coatings. Our lineup ranges from products based on mineral oils or native oils, specialty-emulsions and organosilicone-based solutions to silicone-free and star-polymer defoamers.

One of the outstanding innovations in the BASF defoamer portfolio is our award-winning FoamStar technology. It is based on a hyper-branched polymer with a 3-dimensional star-shaped structure, containing hydrophilic as well as hydrophobic elements. Unlike conventional mineral-oil and silicone defoamers, our FoamStar technology breaks down foam on a molecular level. It acts as a unique surfactant interacting with the foam-related surfactants and destabilizes the foam bubbles. When combined with conventional defoamer types, it accelerates bubble-break times and boosts efficiency.
