INCI Name:

Not specified in search results; industrial grade product

Product Name:

Contraspum W Conc

Manufacturer:

Zschimmer & Schwarz

Other Names:

Anti-foam agent W Conc, Defoamer W Concentrate

Uses:

Contraspum W Conc is a highly effective, concentrated anti-foam and defoaming agent specifically designed for use in the textile industry and other aqueous industrial processes. It is a silicone-based emulsion that rapidly destroys existing foam and prevents its formation .

· Textile Industry: Its primary application is in textile processing, where it is used to control foam during operations such as:

  · Pretreatment: Desizing, scouring, and bleaching of fabrics .

  · Dyeing: Prevents foam from interfering with level dyeing, especially in high-agitation equipment like jet dyeing machines, overflow dyeing machines, and winch becks .

  · Printing: Used in print paste formulations .

  · Finishing: Added to finishing liquors to prevent foam formation during application .

· Industrial Applications: Suitable for any aqueous system where foam presents a problem, including:

  · Paper Industry: Pulp and paper processing .

  · Water Treatment: Wastewater treatment plants .

  · Chemical Production: Various chemical processes .

  · Adhesives & Paints: Prevents foam during manufacturing and application .

Origin

Contraspum W Conc is a manufactured synthetic blend. It is formulated by emulsifying silicone-based antifoam compounds (typically polydimethylsiloxanes) with a combination of non-ionic emulsifiers to create a stable, water-dispersible concentrate .

What does Contraspum W Conc do in a formulation?

• Defoamer (Foam Destroyer) : It rapidly collapses existing foam by reducing the surface tension of the foam bubbles, causing them to coalesce and burst .
• Anti-foam (Foam Preventer) : When added to a liquid before foam generation, it prevents the formation of stable foam by inhibiting bubble formation and stabilization .
• Processing Aid: Ensures smooth and efficient operation of industrial machinery by preventing foam-related issues such as pump cavitation, overflow, and uneven treatment of materials .

Safety Profile (Critical):

· General Hazard Classification: The specific hazard classification for Contraspum W Conc is not detailed in the search results. However, as an industrial chemical concentrate, it should be handled with care. The finished diluted product is generally considered safe for its intended use in textile processing .

· Handling & Storage:

  · Store in a cool, dry place away from direct sunlight and extreme temperatures (recommended range: 5-30°C). Protect from frost, as freezing can destabilize the emulsion .

  · Containers should be kept tightly sealed to prevent contamination and evaporation .

  · If frozen, the product may be damaged and should not be used .

· Shelf Life: Approximately 12 months from the date of production when stored properly in original, unopened containers .

· Biodegradability: Silicone-based antifoams are generally not readily biodegradable. However, the product is designed for use in industrial processes where it may be captured or treated in effluent systems. Specific biodegradability data for this blend is not available in the search results.
