DOWSIL™ AFE-1520 is a 20%-active, food-grade silicone emulsion developed as a versatile antifoaming agent for agricultural and beverage industries. It features a white, non-ionic, water-dilutable formulation that disperses easily and remains effective in both hot and cold systems. With a viscosity of 6000 cP, specific gravity of 1.0, and pH around 4, it provides stable foam control without compromising processing efficiency. 

• Powerful Defoaming - AFE-1520 delivers high-efficiency foam suppression due to its low surface tension silicone structure. Comparative testing shows a 70% faster foam collapse rate than conventional organic antifoams. The fine silicone emulsion disperses evenly across liquid surfaces, breaking foam films rapidly and preventing reformation. This results in smooth processing in dynamic systems such as fermenters, clarifiers, and blending tanks.

  
  

• Certified Food Safety - The formulation meets food additive standards established under Japan’s Food Sanitation Law and other international regulations. It contains no harmful reactive residues and is non-toxic under standard processing conditions. Safety testing in food-grade environments demonstrated zero migration and stable performance after 100 thermal cycles at 120°C, ensuring suitability for food and beverage production.

  
  

• Thermal and Chemical Resistance - AFE-1520 maintains its antifoam activity under elevated temperatures and in chemically aggressive solutions. Laboratory trials confirmed stable performance at 150°C and resistance to acids, alkalis, and surfactants with less than 5% loss in effectiveness. This makes it suitable for a broad range of industrial processes where organic antifoams would degrade.

  
  

• Long-Lasting Film - The silicone structure provides persistent foam inhibition with extended operational endurance. In continuous agitation testing over 8 hours, AFE-1520 sustained foam suppression with less than 10% performance decline, outperforming hydrocarbon-based agents. The long retention time minimizes reapplication needs, optimizing dosage control and cost efficiency in large-scale systems.

  
  

• High Chemical Stability - The product is chemically inert and remains non-reactive under most operational conditions. Stability evaluations under varying pH (2–9) and temperature (0–150°C) ranges confirmed no phase separation or compound breakdown. This ensures consistent quality and prevents contamination or interference with other substances in multi-ingredient processing setups.

• Food Processing - AFE-1520 provides reliable foam control in sauce mixing, oil refining, and syrup boiling operations. It reduces air entrapment and ensures uniform texture during continuous food manufacturing. Tests in sauce production lines showed a 50% reduction in batch time due to improved foam collapse.

  
  

• Chemical Manufacturing - In chemical blending and surface treatment processes, AFE-1520 suppresses foam formation caused by surfactant reactions. Foam height testing indicated a rapid collapse rate under 10 seconds after addition, maintaining smooth agitation and preventing overflow during synthesis.

  
  

• Agricultural Chemicals - The product is highly effective in controlling foam during formulation of fertilizers and pesticide emulsions. Stability trials revealed consistent foam inhibition across a wide pH range, ensuring ease of mixing and dosing in agricultural liquid concentrates.

  
  

• Beverage Manufacturing - It improves production efficiency in brewing, juice clarification, and carbonated beverage processing by reducing foam formation. In brewery trials, AFE-1520 maintained clarity and process flow stability, enhancing filtration performance by 25%.

  
  

• Meat and Seafood Processing - The antifoam controls surface frothing in protein-rich broths and wash waters. During testing, foam volume reduction exceeded 85% within one minute of application, ensuring cleaner operations and improved yield in meat and seafood processing lines.

  
  

• Fermentation Systems - AFE-1520 supports consistent microbial fermentation by minimizing foam that interferes with oxygen transfer and nutrient distribution. Industrial-scale fermentation trials demonstrated a 30% increase in fermentation efficiency when silicone antifoam was applied.

  
  

• Wastewater Treatment - The product provides stable defoaming in aeration tanks, sludge digesters, and effluent clarifiers. Long-term testing showed effective suppression of biological foam at concentrations as low as 10 ppm, leading to reduced overflow and easier sludge management.

  
  

• Vegetable Processing - In washing and blanching systems, AFE-1520 prevents foam buildup that can disrupt water circulation. Controlled tests in vegetable blanching tanks achieved complete foam elimination within 90 seconds, ensuring stable throughput and consistent product quality.
