Application

FLAVANTHRONE serves as a vital vat dye used predominantly in textile applications, characterized by its brownish-yellow needle-like structure that easily dissolves in dilute alkaline solutions. Presented as a yellow powder with a greenish shade, it consistently withstands high temperatures up to 180°C and offers excellent light fastness with a rating of 7, ensuring durability under various conditions. Its resistance to both acidic and alkaline environments is rated at 5, and its fastness to bleeding maintains the same robustness. With an oil absorption capacity between 45-50% and a specific surface area of 27 m²/g, FLAVANTHRONE demonstrates efficient application properties. The dye also maintains a density of 1.50 g/cm³ and limits residue on an 80 mesh to a maximum of 5.0%, while maintaining minimal water solubility and volatility at 105°C, both at 1.0% max. Additionally, FLAVANTHRONE ensures tinting strength within the 100-105% range, making it an optimal choice for achieving vibrant and lasting textile colors.
