Q1: What is the primary application field for Sanodal Turquoise PLW Liq. Pigment?
A: Sanodal Turquoise PLW Liq. Pigment is specifically developed for coloring anodized aluminum surfaces, particularly in architectural and industrial anodizing processes where high chroma, lightfastness, and electrolyte stability are required.
Q2: Is this pigment compatible with standard sulfuric acid anodizing electrolytes?
A: Yes — Sanodal Turquoise PLW Liq. Pigment is formulated to remain stable and dispersible in conventional sulfuric acid-based anodizing baths, including both ambient and refrigerated operating conditions, without significant precipitation or bath contamination.
Q3: How should the pigment be dosed during the anodizing process?
A: Dosage is typically adjusted based on desired shade intensity and bath volume; it is generally introduced as a pre-diluted solution and maintained via continuous or periodic replenishment. Final concentration usually ranges from 0.1% to 2% by weight relative to the electrolyte, depending on process parameters and target color depth.
Q4: Does this liquid pigment require special handling or storage conditions?
A: Store in original sealed containers at temperatures between 5 °C and 30 °C, away from direct sunlight and freezing conditions. Avoid prolonged exposure to extreme pH shifts or strong oxidizing agents prior to dosing. No special PPE beyond standard industrial hygiene practices is required for routine handling.
Q5: Can Sanodal Turquoise PLW Liq. Pigment be used in combination with other Sanodal pigments?
A: Yes — it is fully compatible with other pigments in the Clariant Sanodal liquid pigment range for shade tuning, provided compatibility testing is performed under actual production conditions to confirm uniform co-deposition and absence of interaction effects.
