Q1: What is the primary function of SILTALLUX 7780 in coating and ink formulations?
A: SILTALLUX 7780 is a high-performance pearlescent pigment based on mica coated with titanium dioxide, designed to deliver strong chromatic silver-white interference effects, excellent brightness, and good orientation in solvent-based and radiation-curable systems.
Q2: Is SILTALLUX 7780 suitable for use in automotive refinish coatings?
A: Yes — it is widely used in premium automotive refinish and OEM topcoats where high gloss, distinct flop, and robust weather resistance are required. Its platelet structure supports good leveling and film integrity when properly dispersed.
Q3: How should SILTALLUX 7780 be dispersed to achieve optimal optical performance?
A: Optimal dispersion is achieved using low-shear mixing methods such as dissolvers or dual asymmetric centrifugal mixers. High-shear processes like bead milling or ultrasonication must be avoided, as they may damage the delicate platelet morphology and reduce luster and color strength.
Q4: Can SILTALLUX 7780 be used in waterborne systems?
A: While primarily optimized for solvent-borne and UV-curable applications, it can be incorporated into select waterborne systems with appropriate surfactant stabilization and pH control. Performance validation under end-use conditions is recommended due to potential sensitivity to ionic strength and shear history.
Q5: What are key handling precautions during processing?
A: As with all fine particulate pigments, avoid inhalation of dust during manual handling. Use local exhaust ventilation and appropriate PPE. Ensure storage in dry, cool conditions to prevent moisture-induced agglomeration, and always pre-wet or slurry before incorporation into viscous media.
