1. Basic Attributes

• Product Name: Silwet 408
• Manufacturer: Momentive (a global leading supplier of silicon-based materials)
• Chemical Category: Alkoxy-modified trisiloxane non-ionic surfactant
• Appearance and Form: Usually transparent to light yellow liquid with good fluidity

2. Core Performance

2.1 Super Spreading and Surface Tension Regulation

• It has extremely strong spreading ability, with a spreading diameter of <43mm at 0.5% concentration, enabling the spray liquid to spread quickly and evenly on the target surface, greatly increasing the coverage area.
• It can significantly reduce the surface tension of aqueous solutions, with a surface tension of only 21.5mN/m at 0.1% concentration, much lower than conventional additives. This helps the spray liquid to better wet and penetrate targets (such as plant leaves, pest bodies, etc.).

2.2 Multifunctional Synergistic Effect

• It has both absorption and adhesion functions, promoting the absorption and retention of the spray liquid on the target surface, reducing liquid loss caused by rain 冲刷 and the like, and improving the persistence of pesticide efficacy.
• It can effectively control flocculation, maintain the stability of the formulation system, and does not significantly increase the system viscosity (viscosity at 25℃ is 35cPs), ensuring the fluidity and processing convenience of the formulation.

2.3 Environmental and Formulation Compatibility

• The pH stability range is 6.5-7.5, which can be adapted to most aqueous and emulsion formulation systems, and has good compatibility with pesticide active ingredients and other additives.
• It is a non-ionic additive with stable chemical properties, a flash point of 118℃, and high safety in use. It also meets the environmental EPA 40CFR§180.1001(c) standard and is suitable for application scenarios with strict environmental requirements.

3. Application Scenarios and Usage Methods

• Tank Mixing: It can be directly tank-mixed with pesticide spray liquid, with a dilution ratio of 3000-5000 times. It is suitable for field spraying, horticultural pest control and other scenarios, which can reduce the spray volume, increase the spray coverage, and enhance the control effect.
• Formulation Addition: It is added in the production stage of pesticide formulations to optimize the spreading and stability of aqueous and emulsion formulations, and enhance the market competitiveness of products.

4. Competitive Advantages

• Outstanding Performance: Compared with conventional spray additives, Silwet 408 has more prominent spreading ability and surface tension reduction effect, which can increase the liquid coverage efficiency by more than 30% while reducing pesticide usage, in line with the concept of green plant protection.
• Functional Integration: It integrates multiple functions such as spreading, absorption, adhesion, and stabilization, which can simplify formulation design and reduce the comprehensive cost of formulations.

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 5-30℃. The shelf life is usually 2-3 years.
• Packaging Forms: Common packages are 20L and 200L plastic barrels, and customized packages can also be provided according to requirements.
