1. Basic Information

• Product Name: SE - 47 Defoamer
• Packaging Specification: 200 kg/blue barrel
• Main Ingredient: Organic silicon, mainly polysiloxane compounds. Through special formulation and process treatment, it has good defoaming and foam - inhibiting properties.

2. Product Characteristics

1. Wide Applicability: It is suitable for many fields, such as household chemicals (dishwashing liquid, laundry detergent, etc.), textiles (dyeing, printing and other processes), interior and exterior wall coatings, water reducers, gas treatment, printing fountain solutions, resin production, etc. It can also play an effective role in industries such as emulsion polymerization, printing paste, asphalt, and petrochemical industry, and can cope with various water - based systems from low concentration to high concentration.
2. Efficient Defoaming and Long - Lasting Foam Inhibition: It can quickly break the surface tension of foam, quickly eliminate the generated foam, and at the same time has good long - lasting foam - inhibiting ability to prevent foam from forming again, ensuring the stable progress of the production process and reducing product quality defects and production efficiency reduction caused by foam problems.
3. Good Chemical Stability: It has excellent acid - resistance, alkali - resistance and temperature - resistance. It can maintain stable defoaming performance in a wide temperature range (about - 10℃ - 150℃) and pH range (pH 2 - 12). It has good compatibility with surfactants, additives and other components in various water - based systems, and will not produce adverse reactions such as flocculation and demulsification.
4. Low Addition Amount: Only a small amount (generally 0.05% - 0.5% of the total system, depending on the actual system) needs to be added to achieve the ideal defoaming and foam - inhibiting effect, thereby reducing the use cost and improving economic benefits.

3. Application Fields

1. Household Chemicals: In products such as dishwashing liquid and laundry detergent, it can effectively eliminate the foam generated during production and use, making the product use more smoothly and avoiding the inconvenience caused by foam overflow.
2. Textile Industry: In processes such as dyeing and printing, it can eliminate the foam generated by mechanical stirring, additive addition, etc., ensuring uniform color of textiles and improving product quality.
3. Coating Industry: It is used in interior and exterior wall coatings to prevent the generation of foam during production and construction, avoid defects such as pinholes and bubbles in the coating, and improve the film - forming quality and decorative effect of the coating.
4. Building Materials Industry: In the production of water reducers, it eliminates foam, ensures the stable performance of water reducers, and improves the working performance and strength of concrete.
5. Petrochemical and Other Industries: In complex systems such as emulsion polymerization, printing paste, asphalt production and petrochemical industry, it effectively controls foam and ensures the continuity of production and product quality.

4. Usage Methods

• Addition Amount: According to the foam condition and requirements of the specific application system, the general addition amount is 0.05% - 0.5% of the total system. It is recommended to conduct a small - scale test first to determine the optimal addition amount.
• Addition Method: It can be added directly during the stirring stage in the production process, or it can be diluted with an appropriate amount of water or the solvent in the system before adding to ensure sufficient dispersion.

5. Storage and Transportation

• Storage Conditions: It should be stored in a cool, dry and well - ventilated warehouse, avoiding direct sunlight and high - temperature environments. The recommended storage temperature is between 5℃ and 35℃. Keep the package sealed to prevent the product from absorbing moisture, volatilizing or being contaminated.
• Shelf Life: Under suitable storage conditions, the shelf life of the product is usually 12 - 24 months.
• Transportation Requirements: It is a non - dangerous chemical and can be transported by conventional means such as road and railway. During transportation, pay attention to avoiding severe collision and inversion to prevent damage to the packaging barrel.
