Q1: What is the primary function of SILTALLUX 8620 in coating and ink systems?
A: SILTALLUX 8620 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 color travel and metallic visual effects in automotive clearcoats, industrial coatings, and decorative printing inks.
Q2: Is SILTALLUX 8620 suitable for water-based formulations?
A: Yes, SILTALLUX 8620 is surface-treated to provide good compatibility and dispersion stability in both solvent-based and water-based systems. However, optimal performance requires appropriate wetting agents and controlled dispersion protocols—especially in low-VOC or high-solids aqueous applications.
Q3: How does SILTALLUX 8620 compare to conventional aluminum or bronze pigments in terms of durability?
A: Unlike metal flake pigments, SILTALLUX 8620 offers superior chemical resistance, non-oxidizing behavior, and excellent UV stability—making it especially suitable for exterior applications where long-term color retention and corrosion resistance are critical. It does not tarnish or degrade under typical atmospheric exposure.
Q4: What is the recommended method for incorporating SILTALLUX 8620 into a formulation?
A: For best results, pre-disperse SILTALLUX 8620 using high-shear mixing or bead milling in a portion of the vehicle or resin solution before adding to the main batch. Avoid excessive mechanical stress during final mixing to preserve particle integrity and optical performance.
Q5: Can SILTALLUX 8620 be used in thermoplastic or thermoset plastics?
A: While primarily developed for liquid coatings and inks, SILTALLUX 8620 has been successfully applied in certain high-temperature thermoplastics—provided processing temperatures remain below the thermal stability threshold of the TiO₂/mica substrate and residence time is minimized. Compatibility testing under actual processing conditions is strongly advised.
