Q1: What is the primary function of ECKART SILTALLUX 7755 in coating and ink systems?
A: ECKART SILTALLUX 7755 is a high-performance pearlescent pigment based on mica coated with titanium dioxide and iron oxide. It delivers strong chromatic shift, excellent brightness, and a soft metallic luster—particularly valued in decorative coatings, automotive refinishes, and specialty printing inks where visual impact and light-dependent color effects are critical.
Q2: Is SILTALLUX 7755 suitable for water-based formulations?
A: Yes, SILTALLUX 7755 is surface-treated to provide good compatibility and dispersion stability in both solvent-based and water-based systems. Optimal performance in aqueous media typically requires gentle dispersion using low-shear mixing and may benefit from compatible rheology modifiers or dispersing aids to prevent agglomeration.
Q3: How does SILTALLUX 7755 differ from standard aluminum or conventional mica pigments?
A: Unlike metallic aluminum pigments, SILTALLUX 7755 offers superior weather resistance, non-flammability, and chemical inertness. Compared to basic mica pigments, its dual-layer metal oxide coating enables richer interference colors, higher reflectivity, and more pronounced flip-flop behavior—making it ideal for premium aesthetic applications where durability and optical complexity are required.
Q4: What is the recommended method for incorporating SILTALLUX 7755 into a formulation?
A: For best results, incorporate SILTALLUX 7755 during the let-down stage using low-shear agitation to preserve particle integrity and orientation. Pre-wetting with a compatible solvent or resin solution is advised. Avoid high-speed dispersion equipment such as bead mills or ultrasonication, which may damage the delicate platelet structure and reduce optical performance.
