Q1: What is the primary functional benefit of SILTALLUX 6755 in coating systems?
A: SILTALLUX 6755 is a high-performance pearlescent pigment based on synthetic mica, engineered to deliver strong chroma, excellent light reflection, and a smooth, uniform metallic sheen—particularly valued in premium decorative and industrial coatings where visual impact and consistency are critical.
Q2: Is SILTALLUX 6755 suitable for water-based formulations?
A: Yes, SILTALLUX 6755 is surface-treated to ensure good compatibility and dispersion stability in both solvent-borne and water-based systems, including acrylic, polyurethane, and alkyd dispersions—though optimal performance requires appropriate wetting agents and controlled dispersion protocols.
Q3: How does SILTALLUX 6755 compare to conventional aluminum or bronze pigments in terms of weather resistance?
A: Unlike metallic flake pigments prone to oxidation or tarnishing, SILTALLUX 6755 offers superior UV stability and chemical inertness due to its ceramic-coated mica substrate—making it well-suited for exterior applications where long-term color retention and gloss stability are required.
Q4: What precautions should be taken during handling and dispersion?
A: To preserve particle integrity and optical performance, avoid high-shear mixing beyond recommended thresholds and use low-impact dispersion techniques such as dissolver blades or rotor-stator systems with controlled energy input. Pre-wetting with compatible solvents or resins is recommended before full incorporation.
Q5: Can SILTALLUX 6755 be used in powder coatings?
A: Yes, SILTALLUX 6755 is compatible with standard thermosetting powder coating systems (e.g., epoxy-polyester and pure polyester), provided that extrusion temperatures remain within typical processing windows and that post-addition methods are used to minimize thermal stress on the pigment platelets.
