What are Polyester Dispersants?
Polyester dispersants are high-performance polymeric dispersants synthesized through polyesterification reactions. They are widely used in various liquid systems to enhance the dispersion of pigments, fillers, and other solid particles. They effectively maintain uniform distribution in the liquid and prevent particle settling and agglomeration.
Mechanism of Action
Polyester dispersants create a stable protective layer on the surface of particles, reducing inter-particle attraction and improving compatibility with the liquid. They effectively prevent particle settling and re-agglomeration, ensuring the uniformity and stability of the system.
Characteristics and Advantages
- High Efficiency: Provides excellent dispersion effects even at low dosages.
- Good Compatibility: Suitable for various liquid systems and compatible with different matrices.
- Excellent Stability: Delivers long-term stable dispersion, preventing particle re-agglomeration.
- Eco-friendly: Meets green chemistry standards, safe and non-toxic, environmentally friendly.
Application Scenarios
- Coatings: Enhances the dispersion of pigments and fillers, improving the color and gloss of coatings.
- Inks: Ensures uniform pigment distribution, enhancing print quality.
- Cosmetics: Guarantees even dispersion of ingredients in cosmetic formulations.
- Pharmaceuticals: Improves stability and efficacy of drug formulations.
