Silcolapse® 5020

• Easy dispersion in aqueous media.
• High foam control capability in a wide variety of foaming media.
• Homogeneous and stable emulsion.
• Chemically inert with regards to the medium to be defoamed.

Silcolapse® 5020 can be used in industries such as:

• Chemical: Detergents and cleaners rubber latex, cutting oil formulations water-based printing inks adhesive formulations.
• Water treatment: Biological step.
• Agrochemicals: Silcolapse® 5020 can be used to control foam formed during manufacture and in the end-use application of many agrochemical formulations.

                       - Emulsifiable concentrates
                       - Suspension concentrates
                       - Water-dispersible granules
                       - Wettable powders.

Silcolapse® 5020 can be used as delivered, or pre-diluted in water or in the foaming medium. In this case, the water is added to the antifoam slowly with slight stirring (do not use high shear mixers). It is recommended not to dilute it less than 1% active material content. Check the dilution stability. The dilution thus obtained can be stored for 24 hours. Silcolapse® 5020 is normally used at concentrations comprised between 10 and 500 mg per kg of the medium to be defoamed. 

The amount of Silcolapse® 5020 required for a particular foam problem depends on several factors, which are:

• Surfactant type
• Surfactant concentration
• pH
• Temperature
• Degree of agitation/aeration.

Each foam problem tends to be unique, sometimes to a particular process or product and even to a specific plant. Small surfactant molecules are more readily displaced from bubble lamella than from large protein or synthetic polymer molecules, hence the latter often require higher concentrations of antifoam to achieve good foam control.

Methods of addition: It is better to add Silcolapse® 5020 to the medium before than foam appears, but it can also be added later to eliminate and control foam. Continuous addition is made using a metering pump or by gravity.

When stored in its original packaging: SILCOLAPSE 5020 may be stored at a temperature between 2 °C/ 36 °F and 30 °C/ 86 °F for up to 15 months from its date of manufacturing.
