What Are the Main Characteristics and Advantages of Solvent Violet 13?

Solvent Violet 13’s performance is rooted in its anthraquinone molecular structure, featuring the following core advantages :

‍Stable Chromatic Performance: It exhibits a pure blue-violet hue with moderate color saturation. The relative color strength is consistently 100±3 (against the standard sample), and the color consistency rate reaches over 92%, ensuring batch-to-batch coloring uniformity .
Reliable Light and Heat Stability: Its light fastness achieves grade 6-7 in full-color applications and grade 5-6 in light-tint systems, meeting the basic requirements of indoor and short-term outdoor products. The thermal stability is excellent, with no obvious discoloration when processed at 280℃ for 10 minutes .
Broad Solubility Spectrum: Insoluble in water (solubility ≤0.005 g/L at 25℃) but well-soluble in common organic solvents such as ethanol, acetone, and xylene. The solubility in xylene can reach 15 g/L at 25℃, facilitating rapid formulation of dye solutions .
Good Compatibility and Migration Resistance: It shows strong compatibility with polyolefins, polystyrene, and other general-purpose plastics, with migration resistance grade 3-4 in PVC materials, effectively reducing dye bleeding issues .
Cost-Effective and Easy to Process: Compared with high-end quinacridone violet dyes, it has a lower production cost while maintaining basic performance. Its fine powder structure (average particle size 5-10 μm) ensures easy dispersion during processing .‍

Application:

‍Mainly used for polystyrene, ABS resin, hard polyvinyl chloride and other kinds of resin color, also can be used for polyester protoplasmic coloring.
It is mainly used for colouring of polystyrene, ABS resin, UPVC and other resins, as well as for colouring of polyester stock, oil products and cosmetics.‍

What Are the Specific Applications of Solvent Violet 13?

Benefiting from its balanced performance and economic advantages, Solvent Violet 13 is widely used in medium and high-end general industrial fields, with the main application scenarios as follows :

General-Purpose Plastic Coloring:

Suitable for coloring PE, PP, PS, and PVC plastics, used in the production of daily necessities such as plastic containers, toy shells, stationery, and cable sheaths.‍

Textile Auxiliaries and Fiber Dyeing:

Applied in the dyeing of acetate fibers and triacetate fibers, as well as the preparation of textile colorants and printing pastes, suitable for producing casual wear and home textile fabrics.

Ink and Coating Production:

Used in solvent-based inks for flexographic printing and gravure printing, as well as wood coatings and metal decorative coatings, mainly for packaging printing (such as plastic bags, cartons) and indoor decoration materials.

Other Industrial Uses:

Employed in the coloring of wax products (candles, floor wax), leather finishing agents, and industrial lubricating oils, expanding its application scope with its stable coloring performance .

How does Solvent Violet 13 compare to Solvent Violet 11?

While both dyes belong to the anthraquinone family, Solvent Violet 13 often provides a slightly different violet hue and may be chosen for specific shade requirements. It also offers similar lightfastness and thermal stability, making it interchangeable in certain applications.

Can Solvent Violet 13 be used for transparent applications?

Yes. Its high transparency makes it ideal for transparent or translucent plastic products, such as clear PET bottles, optical-grade polycarbonate parts, and decorative acrylic items.

Does Solvent Violet 13 maintain color under prolonged heat exposure?

Yes. Solvent Violet 13 retains its vivid violet shade even after exposure to processing temperatures up to 300°C, making it suitable for high-heat extrusion, molding, and other thermal processes.

Is Solvent Violet 13 compatible with other dyes or pigments?

Yes. It can be blended with other solvent dyes or pigments to achieve customized colors. For example, mixing with certain reds or blues can create unique purple tones for branding or specialty effects.
