Purity： 50%
Basic Information
- Brand: Dow Corning
- Model: XIAMETER™ AFE-0050
- Product Type: Silicone Defoamer
- Appearance: Milky White Emulsion
- Origin: USA
- Solid Content: 50%
- pH Value: 6 - 8

Product Characteristics
- High Defoaming Efficiency: Exhibits strong defoaming power even at low concentrations (25 - 50 ppm), enabling rapid elimination of foam.
- Good Persistence: Maintains continuous defoaming performance during dyeing processes and remains stable under high-shear conditions.
- Strong Adaptability: Features stability across a wide range of pH values and temperatures, capable of adapting to various complex working conditions.
- Easy Dispersion: Disperses easily in water for convenient use and demonstrates excellent compatibility with liquid products.
- High Chemical Inertness: Possesses strong chemical inertness, rarely reacting with foaming media and thus not affecting the basic properties of raw materials.
Application Fields
Widely applicable in the following areas:
- Printing paste preparation
- Bleaching and dyeing processes
- Biotin fermentation
- Water-based additive processing
- Pulp and paper making
- Pesticide production
- Detergent manufacturing
- Adhesive production
- Ink and coating industry
- Sewage treatment
Usage Method
- AFE-0050 can be directly added to the foaming system; ensure uniform dispersion. If dilution is required, the storage period of the diluted solution should not exceed 24 hours.
- For systems with high foaming temperatures (> 60°C), it is recommended to add AFE-0050 (or its diluted solution) to the system before the temperature reaches 60°C, followed by uniform dispersion to maximize its effectiveness.
- Based on factors such as the viscosity, temperature, and agitation intensity of different foaming systems, adjust the dosage in 10-ppm increments to select the most cost-effective amount. Generally, a dosage of 30 - 200 ppm ensures ideal defoaming results. For certain industries (e.g., coatings, biological fermentation), the dosage may need to be 2‰ - 5‰.
Packaging and Storage
- Packaging: Usually supplied in 200-kg blue plastic drums; customized packaging is available upon customer request.
- Storage: Should be stored at room temperature in a cool, dry, and well-ventilated area. The shelf life is 12 months. Avoid exposure to direct sunlight and keep away from heat sources; anti-freezing measures are required when the temperature drops below 0°C in winter.
