Quality Control

Our Yellow 3 pigment is manufactured under a stringent quality management system to ensure batch-to-batch consistency. Quality parameters such as color strength, hue, particle size distribution, and rheological properties are rigorously tested against established specifications. While typically supplied to industrial grade standards, production can be aligned with specific customer requirements. A Certificate of Analysis (COA) detailing key specifications is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from incompatible materials. Due to its light-sensitive nature, prolonged direct exposure to sunlight should be avoided to maintain optimal color properties.
