Solvent Blue 35
Solvent Blue 35, marketed as Transparent Blue 2N, is an economical anthraquinone solvent dye producing a bright greenish blue in polystyrene and ABS. It offers high color strength and excellent heat resistance for its class, with a melting point of 127°C. Light fastness is good to excellent in full shade but decreases as titanium dioxide is added, so it is best positioned for transparent or lightly tinted articles. As a cost effective oil soluble dye, it is a common choice for general purpose PS and ABS coloring.

Application Fields
This product is widely used in the following application fields, providing excellent coloring performance and durability:
- Polystyrene (PS)
- ABS
Usage Instructions
Recommended dosage is 0.1-0.5% in PS and ABS transparent shades. The dye melts at 127°C and withstands 260°C processing, so standard PS and ABS melt temperatures dissolve it completely for full strength. Note that light fastness drops in white blends, so reserve this grade for clear or lightly tinted parts. Dissolve in organic solvents where liquid color or dip coloring processes are used.
