• Basic Information
  • Chemical Composition: It is a mixture of alkyl naphthalene sulfonate formaldehyde condensate and block copolymer.
  • Brand: Belongs to Nouryon, a company with rich experience and professional technology in the research, development, production and sales of specialty chemicals.
  • Appearance: Generally in powder form, which is convenient for addition and mixing in various formulations.
• Product Features
  • Steric Hindrance Effect: It can provide a unique steric hindrance effect. Under the synergistic effect of alkyl naphthalene sulfonate formaldehyde condensate and block copolymer, it can effectively inhibit the particle size growth of suspending agents such as spirodiclofen, buprofezin and pyrimethanil, maintain the stability of the suspension system, prevent particle agglomeration and precipitation, and prolong the shelf life of the product.
  • Wetting and Resuspension Properties: It also has a good wetting agent effect, which can reduce the surface tension of the liquid and make solid particles wetted by the liquid quickly. At the same time, it significantly improves the resuspension performance of the suspension, ensuring that the suspending agent can return to a uniform suspension state after simple shaking during storage, thus ensuring the uniformity and effectiveness of drug use.
  • Wide Applicability: It is suitable for various pesticide formulations, including wettable powder (WP), water - dispersible granule (WDG), suspension concentrate (SC), soluble powder (SP), etc. It is especially outstanding in suspension stabilization systems that need to improve resuspension characteristics or adapt to high - hard water application occasions. It has good dispersion and stabilization effects on sulfonylurea products such as nicosulfuron and chlorosulfuron, solid - dosage - form products such as benzothiazolyl acetochlor and captan, as well as suspension concentrate products such as oxine - copper SC.
• Technical Indicators
  • Solid Content: > 98.0%, which means that the proportion of active ingredients in the product is relatively high and the impurity content is low, providing users with a cost - effective solution.
  • Moisture: < 2.0%. The low moisture content can avoid problems such as product caking and performance degradation caused by moisture, and ensure the stability of the product during storage and use.
  • pH Value: The range is 7.0 - 9.0. It can maintain stable performance in a relatively wide pH range and can meet the needs of different acid - base environment pesticide formulations.
• Application Field
  • Pesticide Industry: It is mainly used in the production of pesticide formulations to help pesticide active ingredients disperse evenly in the formulations and improve the use effect of pesticides. For example, in the production of various formulations of different types of pesticides such as insecticides, fungicides and herbicides, it plays a role in dispersion and stabilization, improving the control effect of pesticides on diseases and pests and the inhibitory effect on weeds.
• Formula Example (Taking 50% Indoxacarb WDG as an Example)
  • Indoxacarb Technical: 50%. It is the key component that plays the insecticidal role in this pesticide formulation.
  • Morwet D - 500: 2%. Through its dispersion and stabilization characteristics, it ensures that the indoxacarb technical is evenly distributed in the formulation and can be better dispersed into the environment when used to exert its efficacy.
  • Ufoxane 3A: 3%. It may be used as an auxiliary agent to further optimize the physical properties of the formulation or improve the efficacy.
  • K12 (Sodium Dodecyl Sulfate): 3%. As a surfactant, it enhances the wetting, emulsifying and other properties of the product and assists Morwet D - 500 to play a better role.
  • Ammonium Sulfate: 20%. It can be used as a filler to adjust the physical properties such as density and hardness of the formulation, and may also help the storage stability of the product to a certain extent.
  • Corn Starch: Used to make up the remaining proportion, playing roles such as filling and bonding, which is helpful to form stable water - dispersible granule particles.
• Storage and Packaging
  • Packaging: The common packaging specification is 25 kg/bag, and different specifications of packaging can also be provided according to the actual needs of customers.
  • Storage: It should be stored in a cool, dry and well - ventilated warehouse, avoiding direct sunlight, high temperature and humid environment to prevent the product from absorbing moisture and deteriorating, which will affect the use effect.
