Explore our specialized range of high-performance colorants custom-manufactured to support global paper, plastic, textile, and industrial coating processing requirements.
In modern organic pigments chemistry, the search for highly stable, bright, and durable violet colorants is focused heavily on two main chemical families: C.I. Pigment Violet 23 (Dioxazine Violet) and C.I. Pigment Violet 19 (Quinacridone Violet). As a leading OEM Pigment Violet manufacturer and supplier, Tianjin Sunrise Chem Group offers advanced molecular synthesis and mechanical surface modification services. We help global masterbatch producers, high-end coatings formulators, and packaging ink manufacturers achieve exceptional pigment performance.
Dioxazine Violet (PV23) is known for its high tinting strength, yielding deep, rich violet shades even at very low concentrations. Chemically, its complex carbazole-derived structure provides excellent resistance to solvent dissolution, making it ideal for paints and industrial inks. Quinacridone Violet (PV19), on the other hand, features a linear trans-quinacridone structure. It is highly valued for its outstanding lightfastness and resistance to environmental elements. It is widely used in automotive finishes and industrial coatings.
To meet OEM requirements, a pigment supplier must do more than just deliver standard pigment powders. They must optimize key properties like particle size distribution (PSD), oil absorption rates, and compatibility with various resin systems. By using advanced finishing techniques, such as salt-kneading and polymer-surfactant treatments, we modify the surface properties of Pigment Violet particles. This ensures rapid dispersion and prevents flocculation in water-based, solvent-based, or solvent-free industrial coatings.

Environmental protection is the cornerstone of our innovation. We dedicate ourselves to providing clients with eco-friendly, high-quality colorants that balance productivity with environmental harmony, driving the industry towards a more sustainable development path for a greener textile industry and a sustainable future.
As environmental regulations tighten globally, the industrial colorant market is undergoing a technological transition. Tianjin Sunrise Chem Group is leading this effort with a clear development roadmap:
Developing ultra-fine pigment dispersions with particle sizes under 100 nanometers. This is essential for digital printing inks and thin-film electronics packaging, where avoiding nozzle clogging and maximizing transparency is key.
Phasing out chlorinated intermediates in Dioxazine synthesis. Our research team is designing eco-friendly chemical pathways to minimize halogenated byproducts, ensuring compliance with strict global environmental standards.
Replacing traditional petroleum-derived dispersants with biodegradable, plant-based surfactants. This improves pigment wetting in bio-resins and supports circular economy goals without compromising performance.
Pigment Violet is a versatile colorant used in many different industrial applications. Below are the key scenarios where custom OEM formulations are essential:
In the automotive industry, Pigment Violet 23 is used as a shading component with metallic aluminum pigments and pearlescent pigments. It creates deep, high-chroma violet colors that resist intense UV exposure and outdoor weathering without fading.
Our OEM Pigment Violet pigments are designed to withstand temperatures up to 280°C-300°C. This makes them ideal for engineering plastics like Polyamide, Polycarbonate, and Polyester fibers, preventing color shifts during high-temperature injection molding.
For packaging inks, our pigments provide high gloss, excellent adhesion to polymer films (like PE, PP, and PET), and resistance to migration, food contact materials, and plasticizers.
Cooperating with textile and paper mills for many years shows that the 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 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.
Located near Tianjin Port, one of North China's largest shipping hubs, we ensure rapid logistics response times and direct shipping access to global markets. This geographic advantage helps us minimize lead times and control transportation costs, ensuring stable deliveries even during global supply chain disruptions.
With years of experience, we have successfully established strong partnerships in many countries. Our dedication to meeting global demands and exceeding customer expectations has earned us a reputation as a reliable supplier worldwide. Below is a look at our logistics and shipping operations:
The ZDHC (Zero Discharge of Hazardous Chemicals) program is a collaborative effort by leading brands, retailers, and suppliers in the textile and footwear industry to reduce the use of hazardous chemicals. This certification focuses on eliminating the release of hazardous chemicals into the environment throughout the entire supply chain. Achieving ZDHC Level 3 certification demonstrates that our company has implemented robust chemical management procedures and met strict requirements for chemical handling, wastewater treatment, and pollution prevention.
The Global Organic Textile Standard (GOTS) ensures the organic status of textiles from harvesting raw materials to environmentally and socially responsible manufacturing. The GOTS certification guarantees that textiles are made from organic fibers, chemical inputs are minimized, and strict environmental and labor standards are met throughout production. GOTS certified products are widely recognized as sustainable, safe, and ethical.
Both certifications are key to sustainable textile production. ZDHC focuses on eliminating hazardous chemicals, while GOTS certification guarantees organic and ethical production practices.
