1.Product Description
Achieve Deep, High-Performance Black Coloration with Solvent Black 29 – The Premium 1:2 Chromium Complex Azo Dye for Industrial Applications.
Solvent Black 29, designated as C.I. 61568, is a high-performance 1:2 chromium complex azo dye that represents the gold standard for industrial black coloration in demanding applications . This sophisticated metal-complex dye features a unique molecular structure where a central chromium ion coordinates with two azo ligand molecules, creating exceptional stability, deep color intensity, and outstanding fastness properties .
What distinguishes Solvent Black 29 from conventional black colorants such as carbon black is its molecular-level solubility and dispersion. Unlike particulate pigments that can cause graininess, poor adhesion, or migration issues, this dye dissolves completely in organic solvents, achieving true molecular dispersion that delivers a deep, transparent bluish-black hue with excellent gloss retention . Its bluish-black shade provides exceptional color depth in thin film systems and transparent substrates .
Key differentiators:
1:2 Chromium Complex Chemistry: The coordinated metal-ligand structure provides superior thermal stability, lightfastness, and chemical resistance compared to non-metallized azo dyes .
Exceptional Heat Resistance: Withstands processing temperatures up to 200°C, with heat stability rated Grade A at temperatures from 108°C to 200°C .
Outstanding Lightfastness: Rated 7-8 (on an 8-point scale), ensuring color stability in outdoor and prolonged-use applications .
Superior Solubility: Highly soluble in alcohols, ketones, esters, and aromatic solvents; solubility exceeds 300 g/L in ethanol, ethyl acetate, and toluene .
Low Migration: The metal-complex structure significantly reduces dye migration, making it ideal for packaging and sensitive applications .
Excellent Chemical Stability: Acid and alkali resistance rated Grade A, ensuring performance in aggressive environments .
