STD-6163 is a high-efficiency dispersing additive designed to stabilize pigments and fillers in coating, ink, and polymer formulations. It improves color strength, reduces sedimentation, and enhances processability. Below is a detailed breakdown of its properties, benefits, and applications.
| Property | Spécification |
|---|---|
| Chemical Type | Polymeric dispersant |
| Apparence | Amber to brown viscous liquid |
| Active Content | ≥98% |
| Density (25°C) | 1.05–1.15 g/cm³ |
| Solubilité | Compatible with organic solvents, water |
| Recommended Dosage | 0.5–5.0% (based on pigment/filler weight) |
| Benefit | Description |
|---|---|
| Pigment Stabilization | Prevents flocculation and settling for uniform dispersion |
| Viscosity Reduction | Lowers system viscosity, improving milling efficiency |
| Color Development | Enhances color strength and gloss |
| Broad Compatibility | Works with organic/inorganic pigments, carbon black, and fillers |
| Long-Term Stability | Minimizes hardpack formation in storage |
| Industry | Use Case |
|---|---|

| Inks | Offset, gravure, and flexographic inks |
| Plastics | Masterbatches, colored polymer composites |
| Adhesives & Sealants | Pigmented formulations for uniform appearance |
| Parameter | STD-6163 vs. Conventional Dispersants |
|---|---|
| Dispersion Efficiency | 20–30% faster grinding time |
| Color Yield | Higher tinting strength (≥15% improvement) |
| Sedimentation Resistance | Superior long-term stability (no settling after 6+ months) |
| Foaming Tendency | Low foam generation during processing |
| Aspect | Guideline |
|---|---|
| Storage | Store in cool, dry place (5–40°C); avoid moisture |
| Shelf Life | 18–24 months in unopened containers |
| Safety | Wear gloves/eye protection; avoid inhalation (may cause mild irritation) |
