Explore our primary range of highly stable pigment intermediates and chemical auxiliaries engineered to enhance color depth, thermal resistance, and substrate adhesion across industrial processes.
The global industrial landscape is experiencing a significant paradigm shift toward high-performance color solutions. Ceramic pigments, traditionally recognized for their exceptional thermal and chemical stability, are now finding broader applications outside conventional pottery and tiles. The integration of chemical auxiliaries has revolutionized this sector, enabling ceramic pigments to interact synergistically with organic dyes and polymeric binders.
In modern manufacturing, achieving high-fidelity color consistency on challenging substrates requires more than just raw colorants. Chemical auxiliaries, such as dispersants, leveling agents, and binders, act as performance multipliers. They stabilize pigment suspensions, prevent particle agglomeration at the nanoscale, and optimize the rheological properties of dye mixtures. This synergistic combination ensures vibrant color delivery, enhanced lightfastness, and resistance to extreme environmental factors.
Several factors are driving the demand for specialized ceramic pigment-auxiliary systems:
Tianjin Xiangrui Dyestuff Co., Ltd., together with its subsidiary Tianjin Xiangrui International Trading Co., Ltd., was established in 1998 and 2021 respectively. The company is located in Dasi Industrial Park, Xiqing Economic Development Area, Tianjin, China, and currently employs several hundred staff members.
Over more than two decades, we have evolved from a regional manufacturer into a global scale supplier. Our state-of-the-art facilities and dedicated research teams allow us to continuously refine our production methodologies, ensuring our pigment intermediates and auxiliaries meet the rigorous demands of the global market.
Our strategic location in Tianjin's industrial zone provides excellent logistics and supply chain advantages, allowing us to export high-quality chemical products efficiently to Europe, the Americas, Southeast Asia, and beyond. We combine traditional manufacturing expertise with cutting-edge R&D to deliver chemical solutions that drive value for our global partners.
Understanding how ceramic pigments perform under different industrial conditions highlights the absolute necessity of tailored chemical auxiliaries.
In traditional and technical ceramics, pigments must withstand firing temperatures exceeding 1200°C. Raw pigments alone often experience thermal degradation or uneven dissolution within the glaze matrix.
The Auxiliary Role: Fluxes, deflocculants, and specialized binding auxiliaries are introduced to lower the melting point of the glaze surface slightly and wrap the pigment particles in a protective glass-like shield. This preserves color brilliance and prevents bleeding or fading during the firing cycle.
Modern tile manufacturing relies heavily on digital inkjet printing. The ink must contain high concentrations of inorganic ceramic pigments while maintaining incredibly low viscosity and surface tension to prevent printhead clogging.
The Auxiliary Role: Hyper-dispersants and rheology modifiers are critical. They cover the ceramic pigment particles, providing steric hindrance and electrostatic repulsion. This keeps the particles suspended indefinitely in the organic carrier fluid, ensuring smooth jetting and precise color deposition.
Exterior coatings demand extreme resistance to UV radiation, acid rain, and mechanical wear. Ceramic pigments offer superior durability compared to organic dyes, but they are notoriously difficult to disperse evenly in paint resins.
The Auxiliary Role: Coupling agents (such as silanes) act as a molecular bridge between the inorganic ceramic pigment surface and the organic polymer matrix of the coating. This enhances adhesion, prevents pigment settling, and significantly improves the gloss and scratch resistance of the cured paint.
Xiangrui specializes in the manufacture and supply of a wide range of different dyes, pigments, chemical auxiliaries, and intermediates, which are widely applied in industries such as textiles, papermaking, leather, coatings, inks, plastics, rubber, aluminum, cosmetics, and agriculture.
Our comprehensive product catalog is backed by deep industry knowledge, enabling us to help clients select the precise combinations of pigments and auxiliaries required for their specific substrate applications.
With an annual production capacity of approximately 18,000 tons, Xiangrui is able to provide stable and reliable supply to customers worldwide.
To achieve optimal results, it is essential to understand the chemical interactions that occur when auxiliaries are combined with ceramic pigments.
Inorganic ceramic pigments are inherently hydrophobic and difficult to wet in water-based dye systems. When added to a liquid medium, they tend to clump together, resulting in poor color strength and spotting.
The Solution: Surfactant auxiliaries reduce the surface tension of the liquid, allowing it to penetrate the pigment agglomerates. This facilitates complete wetting and ensures that each individual pigment particle is suspended uniformly, yielding a smooth, consistent dye application.
Once dispersed, pigment particles naturally tend to re-aggregate (flocculate) due to van der Waals forces. Flocculation causes loss of gloss, decreased color strength, and sedimentation in storage.
The Solution: Polymeric dispersant auxiliaries attach to the pigment surface. Their long polymer chains extend into the solvent, creating a steric barrier that physically prevents the particles from coming close enough to stick together, ensuring long-term shelf stability.
For hybrid dyes that combine organic components (such as Azo or Anthraquinone pigments) with inorganic ceramic cores, auxiliaries serve as compatibilizers. They balance the polarities of the different chemical species, preventing phase separation. This results in hybrid dyes that offer the brilliant color range of organic pigments alongside the exceptional durability and heat resistance characteristic of inorganic ceramic materials.

After years of continuous development, Xiangrui has established a fully integrated operation covering research and development, production, sales, and after-sales technical support.

As manufacturing processes become smarter and more environmentally conscious, the synergy between ceramic pigments and chemical auxiliaries continues to evolve.
1. Smart & Responsive Colorants: The next generation of ceramic pigments will incorporate smart materials that change color or properties in response to temperature, light, or structural stress. Developing these materials requires specialized, multifunctional auxiliaries that can protect the responsive core while facilitating environmental interaction.
2. Clean-Label & Bio-Based Auxiliaries: With global sustainability initiatives at an all-time high, there is a push to replace petroleum-derived surfactants and dispersants with bio-based alternatives. Research is focused on deriving effective chemical auxiliaries from agricultural waste and renewable plant sources without sacrificing performance.
3. Artificial Intelligence in Formulation: AI and machine learning are beginning to play a crucial role in predicting the compatibility of pigments and auxiliaries. By analyzing molecular structures, AI models can recommend the exact ratio of dispersants to pigments for a given substrate, significantly accelerating R&D cycles.
4. Reduced Thermal Footprint: Innovating low-temperature firing ceramic pigments relies on auxiliaries that act as highly localized sintering aids. This enables ceramics to achieve complete vitrification and color development at lower temperatures, directly translating to energy savings for manufacturers.
