Clariant Sanolin Quinoline Yellow 70 Pigment – Frequently Asked Questions (FAQ)

Q1: What is the primary chemical class and typical hue profile of Sanolin Quinoline Yellow 70?

A: Sanolin Quinoline Yellow 70 is a high-performance quinophthalone-based organic pigment, offering a clean, bright greenish-yellow shade with excellent chroma and lightfastness. Its molecular structure delivers strong tinting strength and good thermal stability for demanding processing conditions.

Q2: Is this pigment suitable for use in food-contact plastics or packaging applications?

A: Sanolin Quinoline Yellow 70 is not approved for direct food-contact applications under major global regulatory frameworks. It is intended for non-food-contact industrial plastics, coatings, and inks where high color performance and durability are required. Always consult local regulatory guidance and obtain appropriate compliance documentation before use.

Q3: How does this pigment perform under UV exposure and elevated temperatures?

A: This pigment exhibits very good lightfastness and weather resistance, especially when compared to basic monoazo yellows. It maintains color integrity during extrusion and molding processes at typical polymer processing temperatures, though extended residence time above 280 °C may affect performance depending on the matrix and stabilizer system.

Q4: What dispersion methods are recommended for optimal color development in plastics?

A: For best results, pre-dispersion via high-shear compounding—such as twin-screw extrusion—is strongly recommended. The pigment responds well to standard polymeric dispersants and carrier resins. Avoid excessive shear or prolonged melt residence, which may reduce gloss or cause slight hue shift in sensitive formulations.

Q5: Can Sanolin Quinoline Yellow 70 be used alongside other high-performance pigments in multi-pigment systems?

A: Yes—it demonstrates good compatibility with many common high-performance organic pigments and inorganic colorants in co-pigmented systems. However, formulation stability should be verified experimentally, particularly in thermosets or UV-curable systems where reactivity or migration behavior may differ.
