1. Basic Information

• Product Name: HDB-4000 WDG Dispersant, with core features marked as "Hard Water Resistance" and "High Versatility"
• Core Component: Polycarboxylate, a polymer dispersing additive. Its molecular structure is designed to provide hard water resistance and general compatibility.
• Appearance: White granules with uniform particle size, no visible impurities to the naked eye, and good fluidity, which is convenient for feeding and mixing during production.

2. Core Performance

1. Hard Water Resistance: It has "hard water resistance" performance. In hard water environments containing calcium and magnesium ions (such as some farmland in the north and industrial water reuse scenarios), it can effectively inhibit the agglomeration of the dispersion system, maintain a stable dispersion state, and solve the problems of reduced pesticide efficacy and uneven application caused by hard water.
2. General Compatibility: "High versatility" is a prominent advantage. It can be widely compatible with WDG formulations of multiple types of pesticide technical materials such as insecticides, herbicides, and fungicides. There is no need to adjust the dispersant type separately for different technical materials, reducing the formulation research and development and production switching costs of downstream enterprises.
3. Dispersion and Disintegration: It can disintegrate spontaneously and rapidly within 2-3 minutes after contact with water, forming a uniform dispersion system. Within the temperature range of 5℃-30℃, the disintegration speed and dispersion effect are stable, adapting to pesticide application environments in different seasons and regions.
4. Suspension Stability: In different water quality conditions such as soft water and hard water, the suspension rate is maintained above 80%, ensuring that the effective components of pesticides are evenly distributed in the liquid medicine, reducing precipitation, and ensuring the consistency of efficacy during application.
5. Process Compatibility: It is compatible with the conventional extrusion granulation process of pesticide WDG. There is no sticking or strip breakage during the extrusion process. The granules have good toughness and are not easy to break after forming. The amount of water added during production is comparable to that of traditional dispersants, and it can be well compatible with existing production equipment.

3. Application Parameters

• Recommended Dosage: In pesticide WDG formulations, the recommended addition ratio is 3%-5%, which can meet the dispersion requirements of pesticide formulations with different contents.
• Application Scenarios: Mainly used in the preparation of pesticide water-dispersible granules (WDG), especially suitable for pesticide manufacturers in hard water areas, enterprises that need to produce multi-category pesticide WDG, and customers pursuing a balance between formulation versatility and cost.

4. Differentiated Advantages

• Performance Composite: It has the dual advantages of "hard water resistance" and "high versatility" at the same time, adapting to the production scenarios of multi-category pesticide WDG in hard water areas, and has a wider range of application scenarios.
• Cost Economy: The reasonable addition ratio (3%-5%) + high compatibility control costs from two aspects: dispersant procurement and formulation research and development, with outstanding comprehensive cost performance.
• Quality Stability: The molecular structure of polycarboxylate has good stability, and the difference in key performance indicators (disintegration time, suspension rate, etc.) of products in different batches is less than 5%, ensuring the quality consistency of pesticide formulation production.
