1. Core Basic Information

1. Product Name: HDB-1035 Dispersant
2. Chemical Category: High-molecular block polyether non-ionic dispersant, synthesized by block copolymerization of ethylene oxide (EO) and propylene oxide (PO). Its molecular chain contains hydrophilic polyoxyethylene segments and hydrophobic polyoxypropylene segments, achieving dispersion through "steric hindrance + moderate hydrophilic-hydrophobic balance". It combines the low-foaming property of non-ionic systems and the long-term stability of high-molecular structures.
3. Appearance and Properties: At room temperature, it is a colorless to pale yellow transparent liquid, free from visible impurities, precipitation, or stratification, with excellent fluidity. It can be added directly without pre-dilution, simplifying the operation process.
4. Core Functions: Low-foaming dispersion (reducing foam interference in production and application), broad adaptability to different systems, convenient use (reducing operational complexity), while maintaining efficient dispersion stability, suitable for large-scale and refined production needs.

3. Core Performance Advantages

1. Outstanding Convenience in Use: High-purity solvent-free formula, low viscosity (150-300mPa·s), can be added directly to the system through a metering pump or manually, without pre-dilution or heating treatment. Compared with viscous dispersants that require pre-dilution, it shortens operation time by more than 30%, reducing labor and equipment investment costs, especially suitable for small and medium-sized enterprises or continuous production lines.
2. Low-Foaming Property Solves Industry Pain Points: The foam height of 1% aqueous solution is ≤50mm after 5min, no large amount of foam accumulates during production, reducing the addition of defoamers (such as silicone defoamers) by 60%-80%, avoiding the interference of defoamers on dispersion stability; there is no problem of foam clogging the nozzle during application, improving field operation efficiency and reducing liquid waste.
3. Versatility Covers Multi-Scenario Needs: Compatible with all types of pesticide SC systems such as fungicides (epoxiconazole, tebuconazole), insecticides (thiamethoxam, chlorantraniliprole), herbicides (nicosulfuron, 2,4-D), and also suitable for the dispersion of organic pigments (such as phthalocyanine blue) and inorganic powders (such as kaolin). There is no need to adjust the formula for a single system, reducing R&D costs and inventory pressure.
4. Balanced Dispersion Stability and Compatibility: The block structure of the molecular chain can be tightly adsorbed on the particle surface, forming a 3-5nm thick steric hindrance layer. After 14 days of thermal storage at 54℃±2℃, the suspension rate of 20% AI pesticide SC is ≥93%, and the D90 particle size fluctuation is ≤0.2μm; it has no compatibility conflict when compounded with non-ionic surfactants (e.g., Nongru 1601#) and anionic wetting agents (e.g., sodium dodecylbenzene sulfonate), suitable for complex formulation formulas.

4. Application Scenarios

1. Agricultural Field: Production of all types of pesticide suspensions (SC), especially suitable for formulations with high low-foaming requirements (such as post-emergence herbicide SC, foliar fertilizer SC), avoiding foam covering leaves or clogging nozzles during application; also suitable for seed coating systems, the low-foaming property ensures uniform coating and improves seed germination rate.
2. Chemical Field: Low-foaming coating and ink systems (such as water-based industrial paints, printing inks), helping pigments disperse uniformly while reducing the impact of foam on coating flatness and ink printing effects, reducing defoamer dosage and improving product quality.
3. New Material Field: Dispersion of electronic-grade powders (such as electronic ceramic powder, lithium battery cathode material precursor), the low-foaming and high-purity properties avoid the interference of impurities and foam on the performance of electronic components, suitable for high-precision electronic material production needs.
4. Other Fields: Water-based adhesives, daily chemical care products (such as scrub powder dispersion), the low-foaming property improves the user experience, and versatility adapts to different powder raw materials, reducing formula development difficulty.

5. Usage and Storage Instructions

1. Recommended Dosage:
   • Pesticide SC systems: 1.5%-3.5% (based on the total mass of the system), for seed coating and foliar fertilizer systems with high low-foaming requirements, it is recommended to use 2.0%-3.5%;
   • Coating/ink systems: 2.0%-4.0%, for electronic-grade powder systems, it is recommended to use 2.5%-4.0%.
2. Usage Method:
   • Direct addition: No pretreatment is required. After mixing the active ingredient/powder with water, add HDB-1035 directly, stir for 10-15 minutes, and then perform sand milling to simplify the operation process;
   • Stepwise addition: If the system foam is still slightly high, it can be added twice (60% before sand milling, 40% after sand milling) to further suppress foam generation.
3. Storage Conditions:
   • Store in a sealed, cool, dry, and ventilated place, with the temperature controlled at 0℃-40℃, avoiding direct sunlight and low-temperature freezing (slight crystallization may occur below 0℃, and performance can be restored after heating to 10℃-20℃ and stirring evenly);
   • The package should be sealed as soon as possible after opening to prevent dust or impurities from mixing in and affecting product purity.
4. Shelf Life: Under specified storage conditions, the shelf life is 24 months (from the production date), much longer than conventional dispersants (12 months), reducing inventory turnover pressure.

6. Precautions

1. Although it is a low-foaming dispersant, a small amount of foam may still be generated under high-speed stirring (≥5000r/min). It is recommended to control the stirring speed within 3000r/min, or add a small amount of high-efficiency defoamer (such as polyether-modified siloxane, addition amount 0.1%-0.3%);
2. No special protection is required during operation. If it accidentally contacts the skin, rinse with water, and it is non-irritating;
3. Do not store it with strongly acidic substances (pH < 3.0) or strong oxidants (such as hydrogen peroxide) for a long time to prevent molecular chain breakage and affect dispersion performance;
4. Slight color difference (colorless to pale yellow) may exist between different batches of products, which is a normal phenomenon and does not affect dispersion efficiency and low-foaming property, so it can be used with confidence.
