1. Basic Information

• Product Name: SD - 860 Defoamer
• Packaging Specification: 190 kg/barrel
• Main Ingredient: Organic silicon, mainly polysiloxane compounds. Through special processing, it has self - dispersing and high - compatibility characteristics.

2. Product Characteristics

1. Self - dispersibility: Without the need for additional dispersing agents or complex dispersion processes, SD - 860 defoamer can quickly and evenly disperse into various systems. When added to systems such as cutting fluids and coatings, it can spread rapidly, effectively avoiding problems such as poor local defoaming effect or other quality issues caused by uneven dispersion. This greatly simplifies the operation process, saving production time and labor costs.
2. High compatibility: It is highly compatible with various additives (such as rust inhibitors, lubricants, etc.) in cutting fluids, resins and pigments in coatings, and various polymer components in adhesives. There will be no adverse phenomena such as flocculation, demulsification, or delamination, and it will not affect the original chemical and physical properties of the system, such as the cooling and lubricating properties of cutting fluids, the film - forming properties of coatings, and the bonding strength of adhesives.
3. Wide applicability:
   • Cutting fluid field: It can effectively eliminate foam generated by mechanical stirring and the action of surfactants, ensuring the normal operation of the cooling, lubricating, and cleaning functions of cutting fluids, extending tool life, and improving the precision and surface quality of metal processing.
   • Coating and ink industry: During the production and application of coatings and inks, it quickly eliminates foam, avoiding defects such as pinholes, craters, and fish eyes, making the coating or printed pattern more uniform and smooth, and enhancing the decorative and aesthetic properties of the product.
   • Adhesive industry: It inhibits the generation of foam, ensuring the transparency and bonding performance of adhesives, and avoiding problems such as reduced bonding strength and voids after curing caused by the presence of bubbles.
   • High - viscosity systems (concrete, mortar, enamel slurry, etc.): Even in high - viscosity systems such as concrete, mortar, and enamel slurry, it can effectively penetrate and eliminate foam, preventing problems such as loose internal structure and reduced strength of materials caused by foam, and ensuring the quality and performance of products.
4. Efficient defoaming and long - lasting foam inhibition: It has the ability to quickly reduce the surface tension of foam, and can quickly eliminate existing foam. At the same time, its special molecular structure can play a role in the system for a long time, continuously inhibiting the re - generation of foam, providing a stable low - foam environment for the production process, and reducing production interruptions and product quality defects caused by foam problems.
5. Low dosage: Only a small amount (generally 0.05% - 0.3% of the total system volume, the specific dosage needs to be determined by small - scale tests according to the actual foam situation of the system) is required to achieve the ideal defoaming and foam inhibition effect, reducing the use cost and improving the cost - effectiveness of the product.

3. Application Fields

1. Metal processing industry: Suitable for various types of cutting fluids, such as fully synthetic cutting fluids, semi - synthetic cutting fluids, and emulsified cutting fluids, to meet the defoaming needs of different metal processing processes (turning, milling, drilling, etc.).
2. Coating and ink industry: Can be used in the production and application of water - based coatings, solvent - based coatings, powder coatings, and various inks (offset printing inks, gravure inks, flexographic inks, etc.).
3. Adhesive industry: Widely used in different types of adhesive products such as water - based adhesives, solvent - based adhesives, and hot - melt adhesives.
4. Building materials industry: Plays a defoaming role in the production and application of concrete and mortar, as well as in the processing of similar high - viscosity materials such as enamel slurry, ensuring material quality.

4. Usage Methods

• Dosage: First, conduct small - scale tests in the laboratory for specific application systems. According to the severity of foam and the characteristics of the system, determine the optimal dosage. The general dosage range is 0.05% - 0.3% of the total system volume.
• Adding method: It can be directly and slowly added to the system during the stirring stage of the production process, and then stirred evenly; For some systems with strict requirements on the adding process, the defoamer can also be diluted with an appropriate amount of system solvent (such as a diluent for coatings in coatings), and then slowly added to the system, with continuous stirring to ensure that the defoamer is fully dispersed.

5. Storage and Transportation

• Storage conditions: Should be stored in a cool, dry, and well - ventilated warehouse, avoiding direct sunlight and high - temperature environments. The recommended storage temperature is controlled between 5℃ and 35℃. Keep the packaging sealed to prevent the product from absorbing moisture, volatilizing, or being contaminated. The shelf life of unopened products is usually 12 - 24 months.
• Transportation requirements: It is a non - dangerous chemical and can be transported by conventional methods such as road and railway as ordinary goods. During transportation, care should be taken to avoid severe collision and inversion to prevent damage to the packaging barrel and affect product quality.
