Q1: What is the primary functional benefit of SILTALLUX 6880 in coating systems?
A: SILTALLUX 6880 is a high-performance pearlescent pigment based on mica coated with titanium dioxide, engineered to deliver strong chromatic shimmer, excellent light reflectivity, and superior orientation in solvent-based and radiation-curable coatings — particularly where metallic-like depth and clean color travel are required.
Q2: Is SILTALLUX 6880 suitable for use in automotive clearcoats?
A: Yes, SILTALLUX 6880 is widely used in OEM and refinish automotive topcoats, including basecoat/clearcoat systems. Its chemical stability, UV resistance, and compatibility with common acrylic and polyurethane resins support demanding performance requirements without compromising gloss or long-term weatherability.
Q3: How should SILTALLUX 6880 be dispersed to achieve optimal optical effects?
A: For best results, gentle dispersion using low-shear mixing (e.g., dissolvers or planetary mixers) is recommended to preserve flake integrity. Avoid high-shear grinding or bead milling, which may damage the delicate mica substrate and reduce luster. Pre-wetting with compatible solvents or resin solutions prior to incorporation enhances uniform distribution.
Q4: Can SILTALLUX 6880 be combined with other effect pigments in a single formulation?
A: Yes, it is commonly blended with aluminum flakes, iron oxides, or other pearlescents to create complex visual effects. However, careful sequencing during addition and thorough compatibility testing are advised to prevent flocculation or settling issues, especially in multi-pigment systems.
Q5: What are the key storage recommendations for maintaining pigment quality?
A: Store in original sealed containers in a cool, dry environment away from direct sunlight and moisture. Avoid temperature extremes and prolonged exposure to humid conditions, as moisture absorption may affect dispersibility and handling characteristics.
