Toynol® DS-192P Dispersing Agent
1 🎯 Abstract
Toynol® DS-192L/192P are high-performance water-based dispersing agents, composed of a mixture of high molecular weight block copolymers with pigment anchoring groups and surfactants. They have good wetting effect on pigments and fillers, outstanding deflocculation, and provide powerful charge repulsion. As universal dispersants for organic and inorganic pigments, they can reduce the viscosity of grinding systems and improve the color development of millbases. APEO-free, environmentally friendly.

3 🛠️ Application Guide
3.1 Recommended Application Fields
Applicable Pigments/Powders: Inorganic powder materials (alumina modification), carbon blacks (including neutral color carbon black, conductive carbon black BP-2000), phthalocyanine pigments
Applicable Products: Water-based inks, architectural coatings, wood and furniture coatings, automotive coatings, can coatings, anticorrosive paints, leather coatings
3.2 Usage Methods and Recommended Dosage
3.2.1 Recommended Dosage
Alumina powder: 0.5-1% (based on pigment, calculated by dispersant solid content SOP)
Neutral color carbon black: 50-100% (based on pigment, calculated by dispersant solid content SOP)
Conductive carbon black (BP-2000): 50-60% (based on pigment, calculated by dispersant solid content SOP)
3.2.2 Operation Guidance
First add dispersant into water, then add powder, stir at 4000rmp/min for 10min. After the powder is completely wetted, add grinding glass beads to start timing grinding.
Toynol® wetting agents can accelerate original powder wetting.
Adding Toynol® defoamers can quickly eliminate grinding foam.
To obtain optimal performance, Toynol® additives must be added to water before resin and pigment.
It is advisable to conduct gradient tests to determine the optimal dosage.
3.2.3 Grinding Operation
Equipment: Dispersing sand mill; Grinding Media: Glass bead (0.8-1.2mm), filling rate 70%; Parameters: 3000rmp/min for 60min
3.2.4 Performance Evaluation
Fineness measure: Scraper fineness meter
Shelf stability: Take a certain amount of alumina slurry into a measuring cylinder with a stopper, place it at 40℃ constant temperature for 5 days, and observe the layering of the alumina slurry after a period.
Centrifugal stability: Take 20ml millbase into centrifuge tube, centrifuge for 10min under 3000r/min, then take out to observe the layering of millbase. Pour out liquid and calculate the amount and percentage of precipitate.
Viscosity evaluation: Use Brookfield rotational viscometer
Viscosity stability: Store millbase in 100ml wide-mouth bottle at 40℃ for 24 hours, measure viscosity change; ±50% change is regarded as qualified.
3.2.5 Application Reference Examples
Note: ●:Excellent ◎:Good
ExampleⅠ (Experimental pigment: Alumina powder, powder content 60%)
| Component | Dosage |
| Pigment content | 60 |
| Dispersant dosage (as supplied) | 1.8 |
| Defoamer (Toynol®) | 0.1-0.3 |
| Wetting agent (Toynol®) | 0-0.3 (as appropriate) |
| Water | Add to 100% |
Remarks:Put alumina and Toynol DS-192 series dispersing agents together through grinding, pulping, dusting and drying to get modified alumina powder. The modified powder can provide "instant" dispersion effect while soluble in water.
ExampleⅡ (Experimental pigment: Carbon black C-168, powder content 20%)
| Component | Dosage |
| Organic pigment content | 20 |
| Dispersant dosage (as supplied) | 30 |
| Defoamer (Toynol®) | 0.1-0.3 |
| Wetting agent (Toynol®) | 0-0.3 (as appropriate) |
| Water | Add to 100% |
Operation Note:First add dispersant into water, then add powder, stir at 4000rmp/min for 10min. After the powder is completely wetted, add grinding glass beads to start timing grinding.
