1. Basic Information

• Product Name: HDB-3800UA/3800UP WDG Super Dispersant, with core features marked as "Anti-Triple Hard Water" and "Ultra-High Versatility"
• Core Component: Maleic Anhydride Hyperbranched Grafted Acrylic Acid, a hyperbranched polymer dispersing additive. Its molecular structure is endowed with excellent dispersion and compatibility performance through hyperbranched grafting technology.
• Appearance: White to off-white granules with fine and uniform particles, no visible impurities to the naked eye, and good fluidity, which is convenient for feeding and mixing in the production process.

2. Core Performance

1. Hard Water Resistance: It has the core performance of "anti-triple hard water". In hard water environments with extremely high concentrations of calcium and magnesium ions (such as northern high-hardness water irrigation areas and industrial wastewater reuse scenarios), it can effectively inhibit the agglomeration of the dispersion system, maintain a long-term stable dispersion state, and solve the problems of pesticide efficacy attenuation and uneven application caused by hard water.
2. General Compatibility: "Ultra-high versatility" is a prominent advantage. It can be widely compatible with WDG formulations of all types of pesticide technical materials such as insecticides, herbicides, and fungicides. There is no need to develop separate dispersant schemes for different technical materials, which greatly reduces the time and economic costs of formulation research and development and production switching for downstream enterprises.
3. Dispersion and Disintegration: It can achieve rapid spontaneous disintegration within 1 minute after contact with water, forming a fine and uniform dispersion system. Within the temperature range from 5℃ low temperature to 35℃ high temperature, there is no obvious fluctuation in disintegration speed and dispersion effect, adapting to pesticide application needs under extreme temperatures.
4. Suspension Stability: In different water quality conditions such as soft water, moderately hard water, and triple hard water, the suspension rate is maintained above 90%, ensuring that the effective components of pesticides are evenly distributed in the liquid medicine for a long time, reducing precipitation, and ensuring stable efficacy throughout the application process.
5. Process Compatibility: It is compatible with various processes such as extrusion granulation and spray granulation of pesticide WDG. There is no sticking or strip breakage during extrusion, and the granules have high strength and are not easy to break after forming. The amount of water added during production is reduced by 30% compared with traditional dispersants, significantly reducing drying energy consumption and cycle time.

3. Application Parameters

• Recommended Dosage: In pesticide WDG formulations, the recommended addition ratio is 2%-4%. A low dosage can meet the dispersion requirements of ultra-high content (such as above 90%) pesticide formulations, and the advantage in raw material cost control is significant.
• Application Scenarios: Mainly used in the high-end preparation of pesticide water-dispersible granules (WDG), especially suitable for large-scale pesticide manufacturers in hard water areas, group enterprises with large-scale production of multi-category pesticide WDG, and customers pursuing extreme formulation versatility and cost efficiency.

4. Differentiated Advantages

• Technological Leadership: Adopting maleic anhydride hyperbranched grafted acrylic acid technology, the molecular structure has both the steric hindrance effect of hyperbranched structure and the strong adsorption performance of acrylic acid, achieving technological breakthroughs in dispersion, hard water resistance, and versatility.
• Cost Optimization to the Extreme: The combination of low dosage (2%-4%) and full-category compatibility compresses costs from three aspects: dispersant procurement, formulation research and development, and production energy consumption. The comprehensive cost performance is far superior to ordinary dispersants.
• Quality Stability: The hyperbranched molecular structure is extremely stable, and the difference in key performance indicators (disintegration time, suspension rate, etc.) of products in different batches is less than 3%, ensuring a high degree of consistency in pesticide formulation production.
