Our Products for Defoamers

SIPERNAT^® specialty silica and AEROSIL^® fumed silica are used in defoamer, foam inhibitors, foam regulators and/or deaerator formulations based on various hydrophobic liquids such as mineral oil, silicone oil and/or vegetable oil. Properly dispersed in oil, SIPERNAT^® and AEROSIL^® effectively disrupt the formation of bubbles in most kinds of foams by impairing bubble stability and causing bubbles to burst as they begin to form.

Detailed product and application information can be found in brochure TI 1313 – “Specialty Silica for Defoamer” 

SIPERNAT^® specialty silica and AEROSIL^® fumed silica are effective defoamer boosters (hydrophobic & hydrophilic). 

SIPERNAT^® specialty silica grades are preferred as carriers for powder defoamer.

AEROSIL^® fumed silica is often used as a rheology modifier and antisettling agent in oil and emulsion formulations.

Defoamer Boosters - Hydrophobic

SIPERNAT^® D 10 / SIPERNAT^® D 11 / SIPERNAT^® D 13 / SIPERNAT^® D 17 

Hydrophobic SIPERNAT^® specialty silica allows for the convenient manufacture of effective defoamer and/or foam inhibitors. SIPERNAT^® D 10, SIPERNAT^® D 11, SIPERNAT^® D 13, and SIPERNAT^® D 17 offer the optimal particle size for many industrial defoamer/deaerator applications.

AEROSIL^® R 202 / AEROSIL^® R 812

Hydrophobic AEROSIL^® fumed silica allows for the convenient manufacture of effective defoamer and/or foam inhibitors. AEROSIL^® R 202 and AEROSIL^® R 812 have the optimal particle size for many industrial defoamer/deaerator applications. 

AEROSIL^® R 972 / AEROSIL^® R 974 / AEROSIL^® R 816

Hydrophobic AEROSIL^® fumed silica allows for the convenient manufacture of effective defoamer and/or foam inhibitors. AEROSIL^® R 972, AEROSIL^® R 974 and AEROSIL^® R 816 already have the optimal particle size for many industrial defoamer/deaerator applications. Due to their adjusted hydrophobicity, these grades are very compatible in various coating applications.

Defoamer Booster - Hydrophilic 

SIPERNAT^® 35 / SIPERNAT^® 383 DS

SIPERNAT^® 35 and SIPERNAT^® 383 DS are ideally suited for in-situ hydrophobization in mineral and/or silicone oil and dry roast hydrophobization. Due to the particle nature, alkaline catalysts are not needed for this reaction. SIPERNAT^® 35 and SIPERNAT^® 383DS are pre-milled for easy processing and optimal defoamer performance.

SIPERNAT^® 320 DS

SIPERNAT^® 320 DS has good reactivity with silicone oil when manufacturing hydrophobic booster silica for defoamer. However, a catalyst is needed for optimal hydrophobization results. SIPERNAT^® 320 DS is already pre-milled for optimal defoamer performance.

SIPERNAT^® specialty silica as Carrier Substance for Powder Defoamers
Liquid, semisolid, or paste-like defoamer formulations can be converted into powder form by means of SIPERNAT® specialty silica allowing for a more precise dosing and homogeneous distribution.

The use of SIPERNAT^® specialty silica as carrier substance for powder defoamer, e.g. for cementious floor leveling, powder detergents and oilfield applications ensures perfect powder flowability and minimizes caking behaviour.

Detailed information can be found in the brochures TI 1360 “SIPERNAT^® and AEROSIL^® – an Essential in Industrial Powder Technology” and TI 1213 “Performance Silica as Flow Agent and Carrier Substance - Recommended Mixing Procedures for Powders and Granulates”.
