Silcolapse® 721

Silcolapse® 721 is a non-ionic aqueous 10% active silicone antifoam and/or defoamer. It offers excellent antifoam and defoaming properties in a wide variety of aqueous applications including those with incidental food contact as well as food processing applications. The product effectively controls foam at concentrations as low as 10 ppm solids, even at elevated temperatures. The product gives good results at wide-ranging pH and provides a cost effective solution where foam is a problem.

Product Applications

Silcolapse® 721 is a broad spectrum antifoaming and defoaming agent which can be used to control or destroy foam in many industrial, food processing and food contact applications. Typical applications in which it can be used include:

  • Beverages, Juices, Sauces and Soup: Many food and beverage applications generate foam, Silcolapse® 721 will reduce or eliminate foam problems during the processing of many food and beverage applications
  • Fruit and Vegetable Washing and Processing: Many fruit and vegetable processes generate foam, Silcolapse® 721 will reduce or eliminate foam in raw fruit and vegetable washing, potato processing and sugar beet and sugar cane processing
  • Dairy Products: Dairy and cheese production and processing can generate foam Silcolapse® 721 will reduce or eliminate foam problems during the processing in many dairy production processes
  • Meat, Poultry and Seafood: Meat, poultry and seafood production and processing can generate foam Silcolapse® 721 will reduce or eliminate foam problems in meat and poultry rendering, egg washing and seafood processing and production
  • Fats and oils: Production and processing materials into edible fats and oils can generate foam Silcolapse® 721 will reduce or eliminate foam problems during processing and production
  • Water / Effluent Treatment: Aerobic and anaerobic water treatment; activated sludge processes, food plant waste water treatment and cooling towers

Technical Details & Test Data

Instructions for Use

Trial tests should be carried out to determine the quantity of antifoam needed to produce best results and assure no adverse interference with product or process performance. Testing should be started at 10 ppm and increased or decreased based on the results. For convenience, Silcolapse® 721 is designed to be used as is so no dilution is necessary. If needed, a 1% active solution can be maded by adding 9 parts water (or foaming solution) to 1 part Silcolapse® 721. Predilution at a level less than 1% is not recommended.
