Silcolapse® 825

• Excellent antifoam efficiency with long lasting foam control performance
• High persistence even in alkaline conditions and at high temperatures.
• Highly efficient compared to conventional organic oil-based antifoams.
•  Excellent pulp drainage.

Silcolapse® 825 is used as is or formulated into emulsions used to control foam in high foaming and chemically aggressive foaming media.

• Pulp industry: Chemical pulping operations like digestion and brown stock washing.
• Oil & Gas industry: Upstream and downstream processes.
• Aggressive Chemical Processes: Any chemical process where standard performance antifoams provide only a marginal benefit.

• Silcolapse® 825 is efficient in aqueous and non-aqueous media.
• Silcolapse® 825 is normally used at low concentrations between 1 and 100 mg/kg (or per liter). In pulp and paper applications typical use rates for 10 % emulsions are 100-2000 grams per ton of pulp.
• Formulated into an aqueous emulsion by using commercially available emulsifiers or silicone emulsifiers like BLUESIL SP 3300.
• Formulated with other Elkem SILCOLAPSE compounds in order to improve or change certain performance parameters.
• Formulated with hydrocarbon/oxygenated solvents for some aqueous/non aqueous media.

When stored in its original packaging: SILCOLAPSE 825 may be stored at a temperature between -20 °C/ -4 °F and 40 °C/ 104 °F for up to 12 months from its date of manufacturing. Comply with the storage instructions and expiration date marked on the packaging. Beyond this date, Elkem Silicones no longer guarantees that the product meets the sales specifications.
