Solvent Red 149

1. Excellent weather resistance

✅ super UV resistance:

Passed the 3000-hour QUV accelerated aging test (equivalent to 5 years of outdoor exposure), with a color difference ΔE < 1.5

Lightfastness grade 7-8 (ISO 105-B02), far exceeding the industry standard (grade 5-6 for common dyes)

✅ extreme environment stability:

It has excellent acid and alkali resistance (pH 3-11) and antioxidant performance

It is suitable for long-term exposure environments such as automotive exterior parts and outdoor building materials

2. Industry-leading thermal stability

🔥 high temperature resistance 320℃ :

There is no decomposition or discoloration in the injection molding of engineering plastics such as PC and PMMA (the temperature resistance of common dyes is only 250℃).

It has been successfully applied in high-temperature scenarios such as LED car lamp housings and engine compartment components

⚡ wide adaptability of process:

Compatible with various processing methods such as injection molding, spraying and extrusion

It shows stability in both solvent-based and water-based systems

3. Safety compliance and environmental friendliness

🌱 international certification complete:

Passed REACH, FDA 21 CFR 73.3110 (Food Contact grade)

Compliant with OEKO-TEX® Standard 100 Class 1 (Safety for infant and toddler products)

♻️ green process:

Solvent recovery technology (recovery rate > 90%) is adopted in the production process.

It does not contain 24 prohibited aromatic amines and heavy metals (such as Pb/Cd/Hg, etc.)

4. Economic and efficient application value

🎨 ultra high tinting strength:

An addition amount of 0.01-0.05% is sufficient to achieve the standard color depth, saving 20% of the usage compared to similar products
