• Basic Information
  • Chemical Composition: It is a mixture of the sodium salt of alkyl naphthalene sulfonic acid condensate and anionic sulfonate.
  • Brand: Produced by Nouryon, a company with rich experience and strong technical strength in the field of specialty chemicals.
  • Appearance: Usually in powder form.
• Product Features
  • Multifunctionality: It acts as both a wetting agent and a dispersant. It can quickly reduce the surface tension of the liquid, make solid particles wetted by the liquid rapidly, and effectively prevent solid particles from aggregating in the system to maintain a dispersed state.
  • Excellent Applicability: Its performance is better than that of Morwet D - 425 in some sulfonylurea, fipronil, and thiophanate - methyl products. In the suspension concentrate (SC) system, it can show good performance whether used alone, in a 1:1 ratio with Morwet D - 500, or in combination with Morwet IP.
  • Granulation and Disintegration Advantages: It makes the extrusion granulation process smoother, and the produced product disintegrates faster, which is conducive to the rapid release of active ingredients when the pesticide is used and improves the efficacy.
  • Formulation Flexibility: For some active ingredients with slightly better hydrophilicity, a complete water - dispersible granule (WG) formulation can be made using only Morwet D - 450, reducing the types and complexity of additives in the formulation.
• Technical Indicators
  • Solid Content: > 98.0%. A high solid content means relatively less impurity content and a higher proportion of active ingredients.
  • Moisture: < 2.0%. The low moisture content helps ensure the stability of the product during storage and use and prevents problems such as caking and decomposition caused by excessive moisture.
  • pH Value: The range is 7.5 - 10.5. It can maintain stable performance within a relatively wide pH range and is suitable for various pesticide formulations in different acid - base environments.
• Application Fields
  • Applicable Formulations: It is widely used in the production of water - dispersible granules (WDG), wettable powders (WP), water - dispersible tablets (WSG), soluble powders (SP), and suspension concentrates (SC).
• Formulation ExampleTake 50% pymetrozine WDG as an example:
  • Pymetrozine Technical: 50%. It is the main component that exerts the pesticide effect.
  • Morwet D - 450: 8%. It plays the role of wetting and dispersing to ensure that the pymetrozine technical is evenly dispersed in the formulation and can be better dispersed in water when used.
  • K12 (Sodium Dodecyl Sulfate): 3%. It is a commonly used anionic surfactant that further enhances wetting and dispersing properties.
  • Ammonium Sulfate: Make up the remaining proportion. It acts as a filler and regulates the physical properties of the product.
• Storage and Packaging
  • Packaging: Usually in 25 - kilogram packaging specifications, and customized packaging can also be provided according to customer needs.
  • Storage: It should be stored in a cool, dry, and well - ventilated warehouse, avoiding direct sunlight and moisture to prevent the product performance from being affected.
