In modern industrial chemistry, Solvent Black 34 represents a cornerstone of metal-complex dye technology. Valued for its intense color strength, robust solubility in polar organic solvents, and superior lightfastness, this dye is universally designated for high-performance applications. These include wood coating stains, gravure packaging inks, spray leather coloration, and plastic polymers. As global manufacturing environments transition toward stricter regulatory compliance and sustainable supply lines, sourcing Solvent Black 34 from a verified, state-of-the-art Chinese manufacturer with comprehensive testing facilities is no longer just a purchasing strategy—it is a critical requirement for business continuity.
Chemically classified as a chromium-complex azo dye, Solvent Black 34 features a unique structural coordination that ensures resistance to thermal breakdown and chemical degradation. Its molecular configuration allows it to dissolve seamlessly in common carrier systems such as ketones (MEK, MIBK), alcohols (Ethanol, n-Propanol, Butanol), and glycol ethers. This high solubility translates into a brilliant, transparent black appearance with low viscosity in varnish or lacquer systems. Formulators choose Solvent Black 34 to avoid the typical agglomeration issues found with carbon black pigments, particularly in transparent coatings.
Key attributes of Solvent Black 34 include:

The global market for metal-complex dyes is shifting toward suppliers who can guarantee both raw material security and regulatory compliance. China continues to lead global production of Solvent Black 34, supported by integrated chemical industrial parks and reliable access to key raw materials. For global purchasing departments, sourcing from a major exporter like Tianjin Sunrise Chem Group offers significant advantages:
Integrated supply chains allow us to secure critical intermediates, preventing the supply interruptions that are common under shifting global trade conditions.
With ZDHC Level 3 and GOTS certifications, our dyes help global brands satisfy strict export requirements for European and North American markets.
Located in the Tianjin industrial corridor, our facilities facilitate rapid domestic transport and direct, efficient international shipping lines.
Dye Spectrophotometry and Dispersion Testing Labs
Procurement teams now prioritize supply partners with verifiable environmental credentials. Meeting the requirements of the Zero Discharge of Hazardous Chemicals (ZDHC) Roadmap to Zero is essential for modern chemical manufacturing. By achieving ZDHC Level 3 Certification, Tianjin Sunrise Chem Group ensures that our Solvent Black 34 is manufactured without restricted hazardous substances, supporting clean production processes for textile, leather, and consumer product brands.
Solvent Black 34 is dynamic, finding utilization across several high-performance industries. Its chemical stability ensures compatibility with diverse resin systems and application technologies:
Solvent Black 34 delivers deep black tones while preserving the natural wood grain. It is highly compatible with nitrocellulose lacquers, polyurethanes, and acrylic coatings, resisting migration and bleeding over time.
Suitable for solvent-based gravure and flexographic inks used on aluminum foil, BOPP, and PET films. Its solubility ensures low-viscosity formulations for stable, high-speed printing runs.
Used in premium leather finishing to achieve deep, rich black shades. The dye penetrates uniformly, providing excellent wet and dry rub fastness under demanding consumer conditions.

Our manufacturing operations prioritize environmental responsibility and compliance, in line with international chemical standards:
The ZDHC (Zero Discharge of Hazardous Chemicals) program is a collaborative effort by major global brands, retailers, and chemical manufacturers to reduce the release of hazardous chemicals throughout the textile and leather value chains. Reaching Level 3 certification—the highest level within the program—indicates that our chemical products, production processes, and supply chain practices meet strict international standards for wastewater management and pollution prevention.
GOTS certification verifies the organic and socially responsible processing of textiles from raw fiber harvesting to manufacturing. Choosing GOTS-certified colorants from Tianjin Sunrise Chem Group helps manufacturers verify that their end products comply with international environmental and social criteria.
As industrial environmental regulations continue to tighten worldwide, the chemical sector must adapt. Tianjin Sunrise Chem Group is focusing its development on three key areas to meet these shifting demands:
We are optimizing the complexation process of Solvent Black 34 to lower the concentration of free ionic chromium in final dye mixtures, easing compliance with strict electronics and packaging standards.
We are expanding our liquid dye options using eco-friendly solvents, helping manufacturers reduce their volatile organic compound emissions during application.
Our manufacturing lines are incorporating automated control systems to improve batch consistency, ensuring reliable color yield and physical characteristics across shipments.
