Q1: What is the primary function of SILTALLUX 6885 in coating and ink formulations?
A: SILTALLUX 6885 is a high-performance pearlescent pigment based on synthetic mica coated with titanium dioxide. It delivers strong chromatic shift, high luster, and excellent lightfastness, primarily used to impart dynamic visual effects—such as interference color play and metallic sheen—in decorative and functional coatings, automotive refinishes, and specialty printing inks.
Q2: Is SILTALLUX 6885 suitable for water-based systems?
A: Yes, SILTALLUX 6885 is surface-treated to ensure good compatibility and dispersion stability in both solvent-based and water-based systems. However, optimal performance requires proper wetting, controlled shear during dispersion, and formulation-specific rheology adjustment to prevent settling or agglomeration.
Q3: How does SILTALLUX 6885 compare to conventional aluminum or bronze pigments in terms of weather resistance?
A: Unlike metallic flake pigments that oxidize or tarnish upon UV exposure and moisture, SILTALLUX 6885 offers superior long-term weather resistance due to its chemically inert, oxide-coated mica substrate. It maintains color consistency and reflectivity under accelerated weathering conditions without significant fading or loss of gloss.
Q4: What are key handling precautions during processing?
A: To preserve particle integrity and optical performance, avoid excessive high-shear mixing, prolonged grinding, or ultrasonication. Use low-to-medium shear dispersion equipment and add the pigment gradually into the vehicle under gentle agitation. Pre-wetting with compatible solvents or surfactants is recommended to support uniform deagglomeration.
