Applications of STD-5041

STD-5041 is widely used in water-based coating systems for its excellent dispersion stability. It is particularly effective for inorganic pigment dispersion, providing high dispersion efficiency and low bubble formation during grinding. It is compatible with alkaline swelling non-associated (ASE) thickeners and hydrophobic modified alkali swelling association (HASE) thickeners, ensuring excellent stability.

Benefits of Using STD-5041

• Enhanced Dispersion: Provides excellent dispersion stability for water-based coating pigments.

• High Efficiency: High dispersion efficiency with low bubble formation during grinding.

• Compatibility: Excellent compatibility with cellulosic thickeners and other additives.

• Stability: Ensures stable viscosity after lacquer finish, with good freeze-thaw stability.

• Safety: Soft odor, no irritation, and stable viscosity.

Usage Instructions

STD-5041 should be added at the grinding stage of coating production. The recommended dosage is 0.3 to 1.0% of the pigment/filler (solid) weight. It can be used in a variety of self-drying systems to enhance the adhesion of the paint film to the metal substrate and improve the flexibility of the paint film.

Safety and Handling

• Ventilation: Use in a well-ventilated area.

• Protective Equipment: Wear protective glasses, gloves, and masks during operation.

• Skin Contact: If it touches the skin, wash immediately with soap and water.

• Eye Contact: If it gets into the eyes, rinse thoroughly with water and seek medical advice.

• Ingestion: If ingested, seek immediate medical treatment.

• Storage: Store at 5-40°C. If frozen, dissolve and mix thoroughly before use.

Conclusion

STD-5041 is a high-performance dispersant designed for water-based coating systems. Its excellent dispersion stability and compatibility with various additives make it a preferred choice for improving the performance of coatings. Proper handling and storage are essential to ensure its safe and effective use.
