Q1: What is the primary functional benefit of ECKART SILTALLIC 7355 in coating systems?
A: ECKART SILTALLIC 7355 is a high-performance pearlescent pigment designed to deliver strong metallic luster, excellent orientation, and enhanced depth perception in solvent-based and radiation-curable coatings—particularly where high gloss and visual impact are critical.
Q2: Is ECKART SILTALLIC 7355 suitable for use in automotive topcoats?
A: Yes, it is widely used in OEM and refinish automotive topcoats due to its exceptional weather resistance, thermal stability during curing, and compatibility with common acrylic and polyurethane binder systems.
Q3: How should ECKART SILTALLIC 7355 be dispersed to achieve optimal optical performance?
A: For best results, use low-shear dispersion techniques—such as dissolver blades or static mixers—to avoid damaging the delicate flake structure. High-speed grinding or bead milling is not recommended, as it may reduce luster and cause particle fragmentation.
Q4: Can this pigment be used in waterborne coating formulations?
A: Yes, ECKART SILTALLIC 7355 is compatible with many waterborne systems, including acrylic and hybrid emulsions—though formulation adjustments (e.g., surfactant selection and pH control) may be required to ensure stable dispersion and prevent agglomeration.
Q5: What is the typical dosage range for achieving strong metallic effects without compromising film integrity?
A: Dosage generally ranges from 0.1% to 2% by weight relative to total formulation, depending on substrate, film thickness, and desired visual intensity. Lower concentrations often suffice for high-gloss applications due to the pigment’s strong reflectivity and efficient orientation.
