Q1: What is the primary application field for Sanodal Deep Black HBL Liq. Pigment?
A: This liquid pigment is specifically developed for coloring anodized aluminum surfaces, particularly in architectural and industrial anodizing processes where deep, uniform black shades with excellent lightfastness and weather resistance are required.
Q2: How is this pigment typically dosed in the anodizing bath?
A: It is added directly to the electrolyte bath as a stable aqueous dispersion. Dosage depends on formulation requirements and desired shade depth, but it is generally used at low concentrations—typically ranging from 0.1% to 2% by weight relative to the bath volume—and adjusted based on bath temperature, current density, and immersion time.
Q3: Is Sanodal Deep Black HBL Liq. Pigment compatible with standard sulfuric acid anodizing processes?
A: Yes—it is formulated for seamless integration into conventional sulfuric acid-based anodizing baths without requiring major process modifications. It demonstrates good stability under typical operating conditions and does not significantly affect oxide layer formation or sealing performance.
Q4: Does this 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 high humidity or extreme temperature fluctuations to maintain dispersion stability and color consistency.
