Q1: What is the primary application of Sanodal Green 3LW pigment?
A: Sanodal Green 3LW is a high-performance, lightfast organic pigment specifically developed for coloring anodized aluminum surfaces via electrolytic deposition (electrophoretic or electrolytic dyeing), delivering consistent, vibrant green shades with excellent weather resistance and process stability.
Q2: Is Sanodal Green 3LW compatible with standard sulfuric acid anodizing baths?
A: Yes — it is formulated for reliable performance in conventional sulfuric acid-based anodizing electrolytes and is compatible with typical bath conditions, including common temperature, pH, and current density ranges used in industrial anodizing lines.
Q3: How does Sanodal Green 3LW perform under UV exposure and outdoor weathering?
A: This pigment offers very good lightfastness and weather resistance due to its optimized molecular structure and stabilization, making it suitable for architectural and exterior applications where long-term color retention is required.
Q4: What is the recommended dosage range for optimal color development?
A: Dosage depends on desired shade intensity, anodizing parameters, and substrate condition, but it is typically used at low concentrations — generally ranging from 0.1% to 2% by weight relative to the bath volume — with precise optimization advised through lab-scale trials.
Q5: Can Sanodal Green 3LW be used in combination with other Sanodal dyes?
A: Yes — it is designed to be compatible with other Clariant Sanodal dyes for tone adjustment and custom shade creation, provided compatibility testing is conducted to confirm uniform co-deposition and absence of interaction effects under specific process conditions.
