Q1: What is the primary application field for Sanodal Deep Black MLW Gran. Pigment?
A: This pigment is specifically developed for use in anodizing electrolytes to produce deep black, high-quality decorative and functional oxide layers on aluminum substrates—commonly applied in architectural, automotive, and consumer electronics components.
Q2: How does the granular form benefit industrial anodizing processes?
A: The granular morphology ensures controlled dissolution kinetics, improved handling safety, reduced dust generation during dosing, and consistent dispersion in sulfuric acid-based anodizing baths—supporting stable bath performance and reproducible color depth.
Q3: Is this pigment compatible with standard sulfuric acid anodizing chemistries?
A: Yes—it is formulated for compatibility with conventional sulfuric acid anodizing electrolytes, including those operated at typical temperatures (18–22 °C) and current densities (1.0–1.8 A/dm²), without adversely affecting bath stability or oxide layer adhesion.
Q4: What are key storage and handling recommendations?
A: Store in a cool, dry place away from direct sunlight and strong oxidizers. Keep containers tightly sealed to prevent moisture uptake. Use appropriate personal protective equipment (PPE), including gloves and eye protection, during handling—consistent with standard industrial pigment safety practices.
Q5: Can it be used for both rack and barrel anodizing?
A: Yes—Sanodal Deep Black MLW Gran. Pigment is suitable for both rack and barrel anodizing configurations, though optimal dosage and agitation conditions may vary depending on part geometry, load density, and bath circulation design.
