Q1: What is the primary particle morphology and surface treatment of ECKART Copper 2000?
A: ECKART Copper 2000 features thin, high-aspect-ratio flake particles with a controlled particle size distribution optimized for metallic effect and dispersion stability. It is supplied with a proprietary organic surface treatment designed to enhance compatibility with common solvent-based and high-solids coating systems.
Q2: Is ECKART Copper 2000 suitable for water-based coatings?
A: While primarily developed and validated for solvent-borne systems, ECKART Copper 2000 can be incorporated into certain water-based formulations—especially when used with appropriate dispersants and pH-stabilized resins. Performance and long-term stability should be verified through application-specific testing.
Q3: How does ECKART Copper 2000 compare to standard copper pigments in terms of oxidation resistance?
A: ECKART Copper 2000 offers improved oxidative stability compared to untreated copper flakes due to its tailored surface protection layer. However, it remains a non-passivated copper pigment and is not intended for long-term outdoor exposure without top-coating or encapsulation in a protective binder system.
Q4: What are recommended dispersion methods for optimal orientation and metallic effect?
A: For best results, use low-shear mixing followed by gentle homogenization—avoid high-speed dissolvers or bead mills that may damage flake integrity. Pre-wetting with compatible solvents and staged addition into the vehicle help achieve uniform orientation and maximize reflectivity.
Q5: Can ECKART Copper 2000 be used in thermoplastic compounds?
A: Yes—it has been successfully processed in selected thermoplastics such as ABS, PS, and certain engineering polymers at temperatures below the onset of significant thermal degradation. Compatibility and pigment retention during melt compounding depend on resin polarity, shear history, and thermal residence time; pilot trials are recommended.
