DENSIPOL WO 3025 Foam Formation

Foam Formation

Foam refers to gas trapped in the form of bubbles within a liquid or solid medium. Foam formation depends on various factors such as surface tension, surface area and pressure of the medium in which the foam is generated. In industrial applications, foam control is crucial for uninterrupted production, efficiency, cost management and product performance. Unwanted foam formation during the production process disrupts the manufacturing process while negatively affecting the quality of the final product. Causes of foam formation include cellulose derivatives, mixing speed, resins, and post-production filling and application methods. Defoamers are chemical additives used to prevent foam formation in environments where foam is undesirable and in industrial processes, or to eliminate foam in environments where foam is already present. Defoamers reduce the surface tension of suspensions or emulsions and prevent foam formation.

Chemipol

Chemipol is a producer of additives and biocides established in Spain in 1979. With its high technology, effective solutions and expert technical support, Chemipol has extensive experience in the defoamer field and has achieved considerable success worldwide in terms of performance and price with its Densipol PA and WO series. DENSIPOL WO 3025 Densipol WO 3025 is a high-quality defoamer that can be added directly to water-based systems and used across a wide pH range with other agents and binders in the system. It provides long-lasting effect. It is a stable product. WO 3025 is hydrocarbon-based and contains oil-based hydrophobic compounds. It is mineral oil-based. Formulated as a mineral oil-based, high-performance next-generation defoamer, it rapidly and permanently eliminates formed foam while also preventing foam formation from the beginning of the process. Densipol WO 3025, offering the optimum solution in terms of price and quality, provides excellent stability and emulsification.

Densipol WO 3025 provides high-efficiency foam control during production. It shows excellent compatibility with the use of different types of binders such as styrene acrylic, acrylic, alkyd (water-based), styrene butadiene and polyvinyl acetate. It is generally recommended to use two-thirds at the beginning and one-third before the binder. Due to its rapid, effective and lasting defoaming and antifoaming performance, high pH resistance and high thermal stability, excellent chemical stability, compatibility with other chemicals and low cost, the DENSIPOL WO series is a preferred and successful defoamer.   Alper Bağcık Technical Sales Manager Asil Kimya ve Boya San.
