Efka Defoamer
Product Description
The Efka series offers silicone-free and silicone-enhanced defoamers engineered to address foam challenges across solvent-based, waterborne, and solvent-free coatings. These additives ensure rapid bubble collapse and long-term foam suppression in high-shear processes, optimizing surface quality and production efficiency .
Compatible with epoxy, polyurethane, and alkyd systems, the defoamers enhance processing stability in industrial wood coatings, automotive finishes, and PVC compounds. Their hydrolytic resistance prevents microfoam formation during grinding, spraying, or roller application, ensuring bubble-free surfaces in architectural and marine coatings.
