Physical Characteristics: Appearing as a green powder, it presents a vivid bluish - green color. It has a high color strength, endowing paints and coatings with a rich and bright green hue. It is insoluble in water and common organic solvents. In concentrated sulfuric acid, it turns olive - green, and precipitates as green when diluted.
Fastness Properties: It boasts excellent light stability, heat stability, weather resistance, and solvent resistance. It can endure long - term sunlight exposure, high - temperature conditions, and various chemical media without significant fading, discoloration, or decomposition.
Advantages in Paint and Coating Applications
Superior Coloring Performance: It offers rich and vivid green colors for paints and coatings, fulfilling diverse aesthetic requirements. Whether for decorative, automotive, or industrial coatings, it imparts a bright and appealing appearance. Its high color strength ensures that even a small amount can achieve a strong coloring effect.
Good Compatibility: It has excellent compatibility with various paint and coating resins, such as alkyd resins, acrylic resins, and epoxy resins. It can be evenly dispersed in the resin matrix, forming a stable coating film without negatively affecting the physical and chemical properties of the coating. This allows for greater flexibility in formulating coatings to meet specific product requirements.
High Stability: By creating a dense and stable interfacial film around the dispersed droplets, it prevents the droplets from coming into contact and coalescing. This significantly enhances the stability of emulsions or dispersions, reducing problems such as phase separation during storage and use. Even under long - term storage or exposure to external factors, it can maintain the quality and performance of the coating.
Synthesis and Production
