High-purity dye formulations, brighteners, and inorganic pigments optimized for advanced industrial manufacturing processes.
Solvent Black 27 (CAS No. 12237-22-8) represents the pinnacle of modern dye design for high-performance organic coatings, industrial inks, plastics, and high-end wood stains. Chemically categorized as a metal-complex azo dye (containing a central trivalent chromium structural coordinate), this specialized colorant exhibits outstanding solubility parameters in polar organic solvents, alcohols, esters, and ketones. Its chemical matrix yields unmatched thermal integrity, lightfastness, and resistance to aggressive chemical migration.
As a leading Solvent Black 27 manufacturer, Tianjin Sunrise Chem Group bridges the gap between raw molecular synthesis and industrial application requirements. Modern global sourcing agents do not merely look for dye suppliers; they require strategic manufacturers capable of ensuring narrow color tolerance parameters, absolute batch-to-batch consistency, compliance with stringent environmental directives, and advanced technical support pipelines.
Deciphering industrial procurement mandates, ESG compliances, and shift towards low-VOC/water-reducible systems.
Global regulations such as EU REACH, RoHS, and TSCA are redefining raw material selections. Manufacturers must supply Solvent Black 27 with minimal free heavy metals (specifically hexavalent chromium and cobalt limits) to satisfy premium automotive and packaging standards.
Relying on trading entities introduces batch variability. Buyers are looking for primary manufacturers that control the aniline, nitrosation, and metal-complexation steps directly to ensure long-term stability and pricing security.
The rise of automated tinting and high-performance digital jetting requires dyes with extremely low filter residue. Pre-dissolved liquid Solvent Black 27 formulations are seeing double-digit year-on-year demand growth.
Integrating Solvent Black 27 into standard medium systems requires deep knowledge of solubility dynamics. Different polar organic structures alter the absorption peak of metal complexes, yielding shifts from reddish-black to bluish-black shades. Sunrise Chem Group provides localized solution profiles:
Ensures rich, deep ebony shades without concealing underlying wood grain textures. Exceptional UV fastness prevents color fading when exposed to direct sunlight.
Exceptional solubility in glycols and benzyl alcohol systems. Sunrise ensures no precipitation over extended storage times, preventing tip blockage.
Easily dispersed in polymethyl methacrylate (PMMA), polystyrene (PS), polycarbonate (PC), and rigid PVC without affecting polymer structural strength.

ZDHC Level 3 Certified Manufacture
GOTS Certified Organic Colors
Quality Standard Confirmed
Cooperating with textile and paper mills for many years shows that our factory has established a strong and reliable business relationship. This kind of long-term collaboration brings numerous benefits, such as consistent orders, shared resources, and mutual technical support. It also indicates that the factory has a good track record of delivering quality products and meeting the needs of its partners.
Our mission is to drive business growth by providing reliable and customized products. Our goal is to make a significant contribution to our customers' success by consistently delivering first-class products and exceptional customer service. By building lasting partnerships, we strive to be a catalyst for our clients' success.
Maintaining uninterrupted global supply chains through advanced chemical warehousing and standard loading protocols.
Mitigating global supply risk through strict quality assurance workflows.
For modern ink and coating manufacturers, regulatory compliance is not negotiable. Standard Solvent Black 27 formulations historically contained levels of free heavy metals that exceed modern legal thresholds. Sunrise Chem Group resolves this by utilizing an advanced synthesis purification step that minimizes residual reaction by-products. This allows our Solvent Black 27 to meet the requirements of the Zero Discharge of Hazardous Chemicals (ZDHC) Roadmap to Zero Programme.
Additionally, we maintain a dedicated pre-shipment inspection process. Our in-house QC laboratory utilizes high-performance liquid chromatography (HPLC) and spectrophotometric color matching to compare each production run against the approved control standard. No batch is delivered without a Certificate of Analysis (COA) specifying particle distribution, moisture levels, residue values, and color strength.
Leading the development of the next generation of eco-friendly metal-complex dyes.
Developing modified Solvent Black 27 variants that maintain stable solubility in green bio-derived solvents such as ethyl lactate and bio-ethanol, reducing volatile organic compounds (VOCs).
Transitioning from fine powders to specialized micro-granular forms to reduce dust generation in customer factories, enhancing occupational safety.
Expanding direct-dissolved liquid metal-complex solutions to eliminate the need for dangerous dissolution steps on the customer factory floor.
Technical answers to key procurement and chemical engineering questions.
A complete selection of chemical dyes, iron oxides, and organic pigments for paper, leather, and plastic coloring.
