China Direct Fast Truq Blue GL / Direct Blue 86 Suppliers | Quality Dye Factory for Industry Use
Direct Fast Truq Blue GL is a blue dye mainly composed of copper phthalocyanine, with excellent physical and chemical properties and very bright color.
Physical and Chemical Properties
- Soluble in hot water and can be dissolved in cold water. The aqueous solution is a bright lake blue color, transparent without precipitation.
- Insoluble in organic solvents and dissolves quickly. The dyeing process is simple.
- Strong alkali stability: pH 7–12 is stable, suitable for alkaline car wash solutions, cleaning agents, etc. (key advantage).
- Alkaline environment (pH 9–12): No fading, no stratification, no precipitation. Suitable for alkaline systems such as car wash solutions, glass water, etc.
- Reacts with strong acids: slightly changes color, recovers to the original color after dilution.
- Sensitive to iron ions. It is recommended to dissolve with soft water.
- Good affinity for cotton, viscose, hemp, and non-woven fabrics. The 100°C dyeing rate is the best.
- Color light: Pure greenish-cyan color, bright and transparent, brighter than ordinary direct blue.
- Dyeing rate: Medium, the amount of dark color ≤ 3%, the uniformity is average, the salt addition amount needs to be controlled.
Core Advantages of Direct Blue 86
- Strong alkali stability (pH 7–12 stable): No stratification, no precipitation, no fading. Stable after storage for 6 months.
- High sun resistance: Sunlight fastness 6–7 grades, no fading after long-term outdoor use.
- Water-soluble and transparent: Fully transparent when diluted with water, no suspended matter, no clogging of the nozzle.
- Phthalocyanine structure: Better color fastness than ordinary direct blue, lower wastewater pressure, environmentally friendly.
- Multi-scenario universal: Direct Fast Truq Blue GL can be used for textile, paper, leather, water-based industrial coloring, etc., with high cost-effectiveness.

Application Scope of Direct Blue 86
- Alkaline car wash solutions, glass water, antifreeze: Preferred for alkali-resistant green blue, transparent blue / cyan color.
- Water-based cleaners, laundry detergents, dishwashing liquids: Alkali-resistant and non-fading.
- Water-based color pastes, bamboo fiber, electro-aluminum coloring.
- Used for cyan dyeing of cotton, viscose, hemp, non-woven fabrics, home textiles, and knitted products.
- Coloring paper (packaging paper, art paper).

Usage Process of Direct Blue 86
Dilution
First, stir and dissolve in 50–60℃ warm water to avoid lumps.
Addition Amount
1–5 parts per million (0.1–0.5g/kg), 2 parts per million is sufficient for a transparent and deep blue color.
pH Control
Neutral to weakly alkaline (pH 8–11), directly add to the car wash solution and stir evenly.
Compatibility
Direct Fast Truq Blue GL has good compatibility with non-ionic / anionic surfactants, does not affect foaming.
Frequently Asked Questions (FAQ)
Direct Fast Truq Blue GL is a blue dye mainly composed of copper phthalocyanine, which gives it a highly stable phthalocyanine structure, excellent physical and chemical properties, and a very bright color.
It has outstanding alkali stability (stable at pH 7–12). In alkaline environments (pH 9–12), it does not fade, stratify, or precipitate, making it ideal for alkaline formulations like car wash solutions and glass cleaners.
Direct Blue 86 features high sun resistance with a sunlight fastness rating of 6–7 grades, ensuring it does not fade easily even after long-term outdoor exposure.
Yes, it is soluble in hot water and can also be dissolved in cold water. It dissolves quickly to form a bright, fully transparent lake blue solution without leaving any suspended matter or precipitation.
It is highly versatile and used for industrial coloring (alkaline cleaners, car wash solutions, glass water), textile printing and dyeing (cotton, viscose, hemp, non-woven fabrics), and other coloring applications like paper and leather.
You should first stir and dissolve the dye in warm water (50–60℃) to prevent clumping. The typical addition amount is 1–5 ppm (0.1–0.5g/kg) under neutral to weakly alkaline conditions (pH 8–11).
