Solvent Violet 36 (CAS 61951-89-1), also known as Transparent Violet RL, is an anthraquinone-based oil-soluble dye. It appears as a dark violet powder and is specifically designed for the coloration of various plastics and synthetic fibers. Its molecular structure provides a unique combination of deep bluish-violet hues and extreme stability under harsh processing conditions, making it a staple in the masterbatch and engineering plastics industry.
1. Feature: Exceptional Thermal Stability
Advantage: Maintains color integrity at temperatures up to 280°C - 300°C.
Benefit: Process Reliability: Perfect for high-temperature injection molding of engineering plastics like PC and PET, ensuring no color fading or shifting.
2. Feature: High Transparency & Brilliance
Advantage: Dissolves completely in polymer melts without scattering light.
Benefit: Premium Aesthetic: Produces crystal-clear, vibrantly colored plastic products, increasing the market value of consumer goods and packaging.
3. Feature: Excellent Migration Resistance
Advantage: Strong affinity for the polymer matrix prevents the dye from "bleeding" or leaching out.
Benefit: Long-Term Durability: Ensures finished products maintain their appearance and do not contaminate adjacent materials or packaging.
Plastic Coloration
The primary use is for transparent and opaque coloring of engineering plastics including PS, ABS, AS, PMMA, PC, PET, and PBT.
Masterbatch Production
Used as a high-concentration colorant in the manufacture of plastic masterbatches due to its excellent dispersion and heat stability.
Smoke & Pyrotechnics
Used in specialized applications for generating colored smoke due to its ability to sublime without decomposition.
Printing Inks
Applied in oil-based inks, gravure inks, and wood stains where high transparency and lightfastness are required.
Packaging: 25kg fiber drums with inner PE bags; or 25kg cartons.
Storage: Store in a cool, dry, and dark environment. Keep containers tightly closed. Avoid exposure to direct sunlight and moisture. Ensure the storage area is well-ventilated.

Q: Does Solvent Violet 36 affect the transparency of PET bottles?
A: No. Because it is a solvent-based dye that dissolves at the molecular level in the melt, it maintains 100% clarity in PET and PC applications.
Q: Can it be used in food-contact plastics?
A: Our Solvent Violet 36 is produced with low heavy metal and primary aromatic amine content. However, compliance with specific regulations (FDA/LFGB) depends on the final concentration. Please request our compliance report.
Q: What is the recommended dosage for transparent PS?
A: For a light violet tint, 0.005% - 0.02% is usually sufficient. For deep shades, 0.05% - 0.1% may be used.
Q: How does the lightfastness compare to other violet dyes?
A: It is significantly superior to many basic or disperse dyes, reaching 7-8 on the blue wool scale, making it suitable for long-life consumer products.
Q: Is it compatible with UV stabilizers?
A: Yes, it shows excellent synergy with typical Hindered Amine Light Stabilizers (HALS) and UV absorbers.
