1. Basic Attributes

• Product Name: Silwet 806
• Manufacturer: Momentive (a leading global enterprise in the silicon-based materials field)
• Chemical Category: High-performance low-foam spreading agent of polyether-modified trisiloxane
• Appearance and Form: Usually a colorless to pale yellow transparent liquid with good fluidity and no obvious odor

2. Core Performance

2.1 Super Spreading and Surface Tension Regulation

• At 0.1% concentration, the surface tension is as low as 21.5mN/m, which can quickly break the surface tension of pesticide spray liquids, enabling the liquid to spread quickly and evenly on target surfaces (such as plant leaves, pest bodies), significantly increasing the coverage area and reducing pesticide usage.
• The critical micelle concentration is only 0.003 wt%, and efficient performance can be achieved with a small amount of addition, highlighting economic practicality.

2.2 Low-Temperature Environment Adaptability

• The pour point is as low as -30℃, and the cloud point is <10℃ (0.1 wt%). It can maintain good fluidity and performance stability in low-temperature environments (such as early spring and late autumn), solving the pain points of conventional additives such as "freezing" and "failure" at low temperatures, and expanding the pesticide application time window.

2.3 Multifunctional Synergistic Effect

• It has both absorption and adhesion functions, which can promote the absorption and retention of the spray liquid on the target surface, enhance resistance to rain 冲刷，and prolong the duration of pesticide efficacy. At the same time, it has low-foam characteristics, avoiding processing difficulties caused by excessive foam during tank mixing or formulation production.
• The viscosity at 25℃ is 35cPs, with moderate fluidity, facilitating production, tank mixing dilution, and spray application, without increasing equipment load due to excessively high viscosity.

2.4 Formulation and Environmental Compatibility

• The pH stability range is 6.5-7.5, compatible with most pesticide aqueous and emulsion formulation systems, and has good compatibility with pesticide active ingredients and other additives (such as emulsifiers, dispersants), without the risk of flocculation and delamination.
• The flash point is 143℃, with high safety in use; it is a non-ionic additive with stable chemical properties, meeting environmental application requirements.

3. Application Scenarios and Usage Methods

• Tank Mixing: It can be directly tank-mixed with pesticide spray liquids, with a dilution ratio of 3000-5000 times. It is suitable for pest control of field crops (such as wheat, corn) and cash crops (such as fruit trees, vegetables), especially suitable for pesticide application needs in low-temperature seasons, which can improve the spreading and penetration effect of the spray liquid in low-temperature environments.
• Formulation Addition: It is added during the production stage of pesticide formulations to optimize the spreading and low-temperature stability of aqueous and emulsion formulations, enhancing the market competitiveness of products in low-temperature regions, such as herbicide and insecticide formulations for early spring in northern China.

4. Competitive Advantages

• Unique Performance: Compared with conventional silicone additives, the low-temperature adaptability (-30℃ pour point) and low-foam characteristics of Silwet 806 are core advantages, which can increase pesticide efficacy by more than 25% in low-temperature environments, while solving foam problems and improving production efficiency.
• Functional Integration: It integrates functions such as spreading, absorption, adhesion, low-temperature stability, and low foam, simplifying pesticide formulation design, reducing the comprehensive cost of formulations, and meeting the application needs of multiple scenarios (normal temperature, low temperature) at the same time.

5. Storage and Packaging

• Storage Conditions: Store in a sealed container in a cool and dry place, avoid direct sunlight, and the recommended storage temperature is -20℃ to 35℃. The shelf life is usually 2-3 years.
• Packaging Forms: Common packages are 10L, 20L, and 200L plastic barrels. Customized packaging (such as small-scale experimental packages) can also be provided according to requirements.
