1. Basic Information

• Product Name: 855E Defoamer (Wacker SD850 Silicone Defoamer)
• Packaging Specification: 200 kg/blue drum
• Main Ingredient: Silicone (polysiloxane compounds), with enhanced defoaming efficiency and system adaptability through special processing.

2. Product Characteristics

1. Efficient Defoaming and Broad Applicability:
   • For the textile industry (such as dyeing, printing, and finishing processes), liquid detergents, and cleaning detergent systems, it can quickly eliminate foam and continuously inhibit foam. It still maintains stable performance in high - temperature, high - alkali, or high - surfactant concentration environments, avoiding process interruptions or product quality defects (such as uneven dyeing of textiles, foam overflow of detergents) caused by foam.
2. Low Dispersion Threshold and Convenient Use:
   • It can be uniformly dispersed in the system without high shear force. It can be added directly or used after dilution, simplifying the production process. Compared with traditional defoamers that require complex dispersion processes, it significantly reduces operation difficulty and equipment requirements, especially suitable for continuous production scenarios.
3. Good Chemical Stability:
   • It is compatible with surfactants, additives in detergents, and textile treatment agents, without affecting the cleaning power, softness, or other functional characteristics of the system. It is resistant to acids, alkalis, and electrolytes, and can play a stable role in different pH environments.
4. Environmental Friendliness and Safety:
   • It meets the environmental protection standards for industrial cleaning and textile treatment, is non - toxic, has no pungent odor, is safe for operators, and is suitable for fields with high safety requirements such as household detergents and textile post - treatment.

3. Application Fields

1. Textile Industry:
   • Suitable for dyeing baths, printing pastes, and textile auxiliary (such as softeners, finishing agents) systems to eliminate foam to ensure uniform fabric color and smooth surface, and improve the quality of textiles.
2. Detergent Industry:
   • Used in the production of liquid detergents (such as laundry detergent, dishwashing liquid) and industrial cleaning detergents to control the foam height, avoid foam overflow during filling or use, and ensure the washing effect at the same time.
3. Other Industrial Scenarios:
   • It can be used in water - based systems that need defoaming such as papermaking pulping and water - based coatings, especially suitable for scenarios with simple dispersion process requirements.

4. Usage Methods

• Addition Amount:The general recommended addition amount is 0.05% - 0.5% of the total system weight. The specific dosage needs to be determined by small - scale tests according to the severity of foam, system composition, and process conditions.
• Addition Method:It can be directly added to the system during the production process, or diluted 10 - 20 times with cold water and then slowly added. It can be used after stirring evenly without additional high - shear dispersion equipment.

5. Storage and Transportation

• Storage Conditions:Store in a cool, dry, and well - ventilated place at 5℃ - 35℃, avoid direct sunlight and high - temperature environments, and keep the package sealed to prevent volatilization or contamination.
• Shelf Life:Under proper storage conditions, the shelf life is 12 - 24 months.
• Transportation Requirements:It is a non - dangerous goods and can be transported as ordinary goods. Avoid severe vibration and inversion during transportation.
