Toynol® DS-195 Series Grinding Dispersants
1. 🎯 Abstract
Toynol® DS-195 Series (including DS-195L and DS-195H) are high-performance, environmentally friendly dispersants specifically designed for aqueous systems. They exhibit excellent wetting properties for pigments and fillers, deliver remarkable anti-flocculation effects, and provide strong charge repulsion performance. By optimizing the dispersion of various powders, these dispersants effectively reduce the viscosity of grinding systems, enhance the color development of color pastes, and ensure the stability of the final products. Free of APEO, they comply with environmental requirements and are suitable for a wide range of industrial applications.

3. 🛠️ Application Guide
3.1 Recommended Application Fields
Toynol® DS-195 Series dispersants are specially suitable for aqueous systems such as water-based inks, architectural coatings, wood and furniture coatings, automotive coatings, can coatings, anti-corrosion coatings, and leather coatings. They provide reliable dispersion solutions for various pigment-based products.
3.2 Usage Methods and Recommended Dosage
Pre-operation Preparation: Check that the product packaging is intact. Ensure the product is in a homogeneous liquid state; no preheating is required under normal storage conditions.
Dosage Calculation:
For iron oxide pigments: Recommended dosage is 20-50% based on pigment weight (calculated by solid content of the dispersant).
For inorganic pigments (e.g., titanium dioxide): Recommended dosage is 3-7% based on pigment weight (calculated by solid content of the dispersant).
Optimal dosage is recommended to be determined through gradient tests according to specific pigment systems and application requirements.
Dilution and Addition:
No dilution is required for direct use; can be diluted with water if needed based on on-site operations.
For best performance, add Toynol® dispersant to water first, then add powders. Mix at 4000 rpm for 10 minutes until the powders are fully wetted. Then add grinding glass beads (0.8-1.2 mm) with a filling rate of 70% and grind at 3000 rpm for 60 minutes.
Optional addition of Toynol® wetting agent can accelerate powder wetting; Toynol® defoamer (0.1-0.3%) can quickly eliminate foam during grinding.
For systems requiring pH adjustment (e.g., transparent iron oxide red), add an appropriate amount of sodium hydroxide to adjust the pH to 8-9.
4. ⚠️ Safety and Storage
Safe Operation: Wear protective gloves and goggles during use to avoid direct contact with skin and eyes. In case of accidental contact, rinse immediately with plenty of clean water. If irritation persists, seek medical attention.
Storage Conditions: Store the product in a clean, cool, dry, and well-ventilated warehouse, away from direct sunlight, high temperatures, and open flames. Protect from moisture and collision during storage and transportation.
Packaging and Shelf Life:
Packaging specifications: 25L plastic drum or 220L iron drum; custom packaging is available upon request.
Shelf life: 12 months under normal storage conditions (sealed, cool, and dry environment). Seal the container tightly after use to prevent contamination or evaporation.
5. ❓ Frequently Asked Questions (FAQ)
Q: What types of pigments are Toynol® DS-195 Series dispersants suitable for?
A: They are widely applicable to iron oxide, transparent iron oxide, titanium dioxide, carbon black, organic pigments, alumina, pearlescent pigments, and other common powders used in aqueous systems.
Q: How to determine the optimal dosage of Toynol® DS-195 Series dispersants?
A: The recommended dosage range is 20-50% for iron oxide pigments and 3-7% for inorganic pigments (based on pigment weight, calculated by solid content). For specific systems, conduct gradient tests to determine the optimal dosage that balances dispersion efficiency, viscosity, and stability.
Q: What are the key performance evaluation methods for the dispersants?
A: Common evaluation methods include:
Centrifugal stability test: Centrifuge 20ml of color paste at 3000 rpm for 10 minutes, observe stratification, and calculate sediment percentage.
Viscosity evaluation: Measure using a Brookfield rotational viscometer; viscosity change within ±50% after 24-hour sealed storage at 40℃ is considered qualified.
Fineness measurement: Determine using a刮板细度计 (film applicator fineness gauge); the target fineness is ≤2.5μm for most applications.
