Reliable Chemical Solutions Tested for Maximum Performance and Stability
Solvent Blue 70 is a high-performance copper phthalocyanine based metal-complex solvent dye characterized by its exceptional solubility parameters in organic systems and unparalleled thermodynamic stability. Within the modern chemical industry, it serves as a critical colorant for premium coatings, clear lacquers, writing inks, wood colorants, and specialty engineering plastics.
As regulatory compliance structures like REACH, RoHS, and TSCA intensify globally, the manufacturing processes surrounding Solvent Blue 70 have undergone significant paradigm shifts. Historical production lines relied on heavy-metal containing structural templates and high-emission washing steps. Modernized facilities in China have integrated closed-loop synthesis systems, effectively reducing heavy metal residue (such as free ionic copper) to parts-per-million levels while maximizing pure dye solids content.
For procurement officers and chemists, obtaining Solvent Blue 70 is no longer merely about color matching. It is about understanding the molecular purity, the solubility margins in ketones and esters, and the structural integrity under intense thermal processing. As the market transitions toward eco-friendly wood stains and low-VOC industrial finishes, the demand for purified, dust-free powder configurations has hit historic highs.

The contemporary procurement landscape demands resilience, cost-effectiveness, and unyielding chemical compliance. Tianjin Sunrise Chem Group stands at the forefront of China's chemical transition into Industry 4.0. Our production lines utilize automated raw material feeders, computerized temperature control modules, and closed-loop filtration mechanisms to minimize structural impurities.
Our long-term collaboration with major textile and paper mills worldwide is built on an unwavering commitment to quality assurance. Each production cycle undergoes a multi-tiered inspection protocol. Spectrophotometers quantify shade accuracy, and liquid chromatography tests verify the absence of hazardous amine residues. By doing so, we ensure that every drum of Solvent Blue 70 shipped from our facility complies perfectly with the most stringent global standards, including REACH, GOTS, and ZDHC Level 3.
Furthermore, China's robust industrial clusters provide an unmatched supply of base chemical precursors (such as phthalic anhydride and copper salts), cushioning our clients against sudden global pricing spikes and supply chain dislocations.

Tianjin Sunrise Chem Group specializes in manufacturing and exporting high-quality dyestuffs. Our diverse product catalogue includes Direct dyes, Acid dyes, Basic dyes, Sulphur dyes, Solvent dyes, Liquid dyes, and Fluorescent dyes.
Backed by decades of industrial research and international trade experience, we have built an unshakeable reputation for reliability and excellence. We serve a broad spectrum of industries, including denim finishing houses, textile mills, tanneries, paper factories, and plastic compounders.
Environmental protection is the core driver of our chemical innovation. We are committed to providing our global client base with sustainable, high-performance colorants that balance productivity with environmental harmony. We strive to lead the coloring industry toward a greener future by offering GOTS and ZDHC Level 3 certified products.
A closer look at our strict analytical testing methods and export operations.
Our analytical labs are equipped with high-performance liquid chromatography (HPLC) instruments and spectrophotometric analysis workstations. Before any drum of Solvent Blue 70 is authorized for port transfer, our QC technicians perform comparative drawdowns against our established Master Standard.
This strict checking protocol ensures that shade deviation (represented by Delta E) is minimized, preventing unwanted shifts in our customers' final products, whether they are manufacturing luxury leather finishes, high-volume writing inks, or structural polymer sheets.
Furthermore, our formulation team works closely with end-users to customize packaging formats (ranging from standard 25kg fiber drums to bulk bags) to match localized plant automation systems.
"Cooperating with major global entities over decades has enabled us to optimize packaging integrity and shipping workflows, guaranteeing cargo arrives safely and moisture-free under all transit environments."
Answering crucial industry questions with data-backed chemical expertise.
Solvent Blue 70 is a copper phthalocyanine metal-complex dye, which confers significantly higher heat resistance (up to 240°C) and superior lightfastness (Grade 7-8) compared to anthraquinone-based dyes like Solvent Blue 35. Furthermore, its solubility in polar organic solvents (such as methyl ethyl ketone and alcohol blends) is notably higher, which helps prevent recrystallization and clogging in writing inks and high-build coatings.
Our factory utilizes computer-controlled automated synthesizer units to monitor key reaction metrics like pH, temperature, and feeding rates. In addition, every batch of dyes is tested before departure using high-precision spectrophotometers. This guarantees that shade deviation (Delta E) remains strictly under 0.5, allowing our clients to maintain consistent colors in their finished product lines.
Yes. Environmental compliance is a core pillar of our operational philosophy. Tianjin Sunrise Chem Group has secured ZDHC Level 3 and GOTS (Global Organic Textile Standard) certifications. This indicates that we have implemented rigorous chemical management policies throughout our manufacturing processes to restrict or eliminate hazardous substances at the source, preventing them from contaminating the environment or harming final consumers.
Because solvent dyes are designed to dissolve in organic media, they are sensitive to humidity and extreme heat during storage. We advise storing Solvent Blue 70 in a cool, dry, and well-ventilated warehouse away from direct sunlight, open flames, and oxidizing materials. Keep the packaging drums sealed when not in use to avoid moisture absorption, which can cause clumping and affect dissolving speeds.
Solvent Blue 70 must comply with region-specific regulations (such as FDA or European Union plastics regulations) if intended for food-contact applications. Generally, metal-complex dyes require strict purity verification regarding trace heavy metal content. Please contact our technical sales team with your specific regulatory targets, and we will provide the corresponding lab analysis certificates (CoA) to support your compliance procedures.
