Solvent Red 197 is a high-performance red solvent dye used for coloring engineering plastics, specialty polymers, and solvent-based systems. As a solvent dye, it dissolves in compatible media rather than remaining as dispersed particles, providing transparent and brilliant red coloration.
Solvent Red 197 is known for its excellent heat resistance, strong tinting strength, and good compatibility with various thermoplastic polymers. It is particularly suitable for applications where clarity, brightness, and thermal stability are required.
SR197 – SolCore®3597 ⬇️TDS
This is a yellowish red pigment recommended for plastics such as PS, SAN, PMMA, PC and PET, providing stable processing characteristics and consistent color performance in industrial applications.

Solvent Red 197 is commonly used in:
Engineering plastics (such as ABS, PS, PC, PMMA)
Transparent and translucent plastic products
Masterbatch for solvent-dye systems
Synthetic fibers
Solvent-based inks
Specialty coatings
It is especially valued in high-temperature plastic processing where stable coloration and transparency are essential.
Solvent Red 197 demonstrates excellent thermal stability, making it suitable for many engineering plastics processed at elevated temperatures.
The dye dissolves well in compatible polymer matrices and organic solvents, enabling uniform and streak-free coloration.
Unlike pigments, Solvent Red 197 provides clear, brilliant red coloration, ideal for transparent or light-transmitting plastic products.
High color intensity allows efficient dosage control and formulation flexibility.
1. Suitable for Engineering Plastics
Its high heat stability supports use in demanding thermoplastic systems.
2. Ideal for Transparent Applications
Provides bright and uniform red shades without opacity.
3. Clean Processing Performance
As a soluble dye, it eliminates dispersion-related issues associated with pigment systems.
Moderate Lightfastness Compared to High-Performance Pigments
Solvent dyes generally offer lower outdoor durability than DPP or other high-performance pigment systems.
Potential Migration Risk
In certain polymer systems, migration or bleeding may occur depending on compatibility and plasticizer content.
Not Suitable for Opaque Coverage
For applications requiring high hiding power or outdoor durability, pigment-based systems may be more appropriate.
Understanding these limitations ensures proper material selection for long-term performance.
When selecting Solvent Red 197, buyers should confirm:
Target polymer type (ABS, PS, PC, PMMA, etc.)
Processing temperature
Required transparency level
Migration resistance requirements
Regulatory compliance for end-use market
Providing detailed processing and end-use information allows suppliers to recommend the most suitable grade.

Solvent Red 197 is mainly used for coloring engineering plastics, transparent plastic products, synthetic fibers, and solvent-based systems.
Yes. It offers good heat resistance suitable for many engineering plastic processing conditions.
Solvent Red 197 dissolves in compatible media, providing transparent coloration, whereas pigments remain dispersed and provide opacity.
It is generally not recommended for long-term outdoor exposure due to moderate lightfastness compared to high-performance pigments.
Migration may occur depending on polymer compatibility and formulation design. Testing is recommended before large-scale production.
