Q1: What is the primary chemical class of Sanolin Violet E2R?
A: Sanolin Violet E2R is a high-performance, non-ionic, solvent-soluble anthraquinone-based pigment, designed for demanding coloration applications requiring excellent lightfastness and thermal stability.
Q2: Is Sanolin Violet E2R suitable for use in food-contact plastics?
A: Sanolin Violet E2R is not approved for direct food-contact applications under major global regulatory frameworks. It is intended for non-food-contact industrial and decorative uses, such as automotive interior parts, technical films, and general-purpose engineering plastics.
Q3: How does Sanolin Violet E2R perform in high-temperature processing?
A: This pigment demonstrates good thermal stability and is suitable for melt-processing temperatures up to approximately 280 °C, making it appropriate for polyolefin and engineering plastic compounding, though performance may vary depending on residence time and shear conditions.
Q4: What solvents or polymer systems offer optimal dispersion for Sanolin Violet E2R?
A: It disperses well in aromatic hydrocarbons, chlorinated solvents, and polar aprotic solvents during masterbatch preparation. In polymers, it shows strong compatibility with polypropylene, polyethylene, ABS, and polycarbonate—typically used at low concentrations where uniform distribution and minimal agglomeration are critical.
