Description

Antifoam B CAS NO 67701-29-5 is a high-performance, silicone-based defoamer and antifoaming agent engineered for industrial processes. It effectively controls and eliminates persistent foam in aqueous and non-aqueous systems, enhancing production efficiency and product quality. This product is essential for manufacturers in sectors such as wastewater treatment, chemical processing, pulp & paper, and coatings & adhesives, where foam can disrupt operations and cause defects.

Application

• Wastewater Treatment: Controls foam in aeration tanks, clarifiers, and during biological treatment processes.
• Chemical Manufacturing: Suppresses foam in reactors, distillation columns, and during mixing and filling operations.
• Pulp & Paper Production: Manages foam in pulp washers, paper coating formulations, and effluent streams.
• Coatings, Inks & Adhesives: Prevents foam formation during manufacturing, mixing, and application to ensure a smooth finish.
• Food Processing (Industrial Cleaning): Used in cleaning-in-place (CIP) systems and equipment wash-downs to prevent foam buildup.
• Textile Processing: Eliminates foam in dyeing baths, finishing chemicals, and printing pastes.
• Agricultural Formulations: Acts as an antifoam agent in the production of pesticides, herbicides, and liquid fertilizers.
• Oil & Gas Processing: Controls foam in drilling muds, gas scrubbing systems, and produced water treatment.
