Core Performance Advantages

  1. Superior Wetting and Penetration: Reduces surface tension of aqueous solutions to below 23 dynes/cm at concentrations as low as 0.01%, enabling rapid wetting and spreading on waxy leaf surfaces and hard-to-wet substrates .
  2. High Compatibility: Compatible with pesticides (herbicides, insecticides, fungicides), plant growth regulators, foliar fertilizers, and water-based coatings, without causing decomposition of active ingredients .
  3. Efficacy Enhancement: Promotes stomatal absorption of active ingredients, reducing pesticide/fertilizer usage by 30%-50% while maintaining or improving efficacy; enhances rainfastness to avoid re-spraying .
  4. Process Stability: Adopts advanced polyether modification synthesis technology, with precise control of molecular weight distribution, ensuring consistent product performance across batches .

Application Fields

1. Agricultural Sector

  • Pesticide Formulation: Used as a formula component or tank-mix additive for herbicides, insecticides, and fungicides to improve spray coverage and bioavailability .
  • Plant Growth Regulation: Enhances absorption of gibberellins, uniconazole, etc., reducing regulator dosage to 1/5-1/10 of the original .
  • Foliar Fertilizer Enhancement: Improves absorption efficiency of phosphate, manganese, and other nutrients when mixed with foliar fertilizers for crops like potatoes and wheat .
  • Recommended Dosage: 0.125%-0.375% (1-3 pints per 100 gallons of spray liquid) for herbicides; 3-16 ounces per 100 gallons for insecticides/fungicides .

2. Coating & Ink Sector

  • Water-based Coatings: Acts as a leveling and wetting agent for water-based polyurethane coatings and UV-curable coatings, improving film smoothness and reducing surface defects .
  • Ink Formulations: Enhances substrate wetting and color uniformity, suitable for various printing materials.

Usage Notes

  1. Conduct small-scale compatibility tests before large-scale application to ensure no crop phytotoxicity or formulation instability .
  2. Dilute with water first before mixing with other products; stir evenly during addition to avoid local concentration imbalance.
  3. Store in a cool, dry, well-ventilated area, avoiding direct sunlight and high temperatures; seal tightly after use to prevent moisture absorption.
  4. Follow relevant safety regulations for chemical handling, wear protective equipment during operation.
