Q1: What is the primary function of SILTALLUX 7770 in coating and ink formulations?
A: SILTALLUX 7770 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 metallic or iridescent visual effects in decorative and functional coatings, inks, and plastics.
Q2: Is SILTALLUX 7770 compatible with water-based systems?
A: Yes — SILTALLUX 7770 is surface-treated to ensure good dispersibility and stability in both solvent-based and water-based systems, including acrylic, polyurethane, and alkyd dispersions. Optimal performance requires proper wetting and dispersion using standard high-shear mixing equipment.
Q3: How does SILTALLUX 7770 perform under UV exposure and outdoor weathering?
A: Thanks to its inert synthetic mica substrate and dense TiO₂ coating, SILTALLUX 7770 exhibits outstanding UV resistance and long-term weathering stability, making it suitable for exterior applications where color retention and gloss durability are critical.
Q4: What is the recommended dosage range for achieving optimal visual effect?
A: Dosage depends on the desired intensity, film thickness, and application method, but SILTALLUX 7770 is typically used at low concentrations — generally ranging from 0.1% to 2% by weight in the final formulation — with adjustments made during lab-scale trials to balance effect, transparency, and rheology.
Q5: Can SILTALLUX 7770 be used in food-contact compliant coatings?
A: SILTALLUX 7770 is not inherently certified for direct food contact. Its suitability for such applications depends on full formulation compliance, including binder system, additives, and regulatory assessment by the end-user. Customers must verify compliance with applicable regional regulations before use in food-contact scenarios.
