Q1: What is the primary chemical class and typical application field for Sanolin Patent Blue V 85 01?
A: Sanolin Patent Blue V 85 01 is an organic pigment based on the triphenylmethane dye family, specifically formulated as a high-performance, heat-stable pigment grade. It is predominantly used in demanding polymer applications such as polyolefins (PP, PE), engineering plastics, and masterbatches where vibrant blue shade consistency and good dispersibility are required.
Q2: Is this pigment suitable for food-contact or pharmaceutical packaging applications?
A: Sanolin Patent Blue V 85 01 is not certified for direct food-contact or pharmaceutical use. It is intended for general industrial and non-regulated applications. Customers requiring compliance with food-contact regulations must consult Clariant’s dedicated food-grade pigment portfolio and obtain formal regulatory documentation prior to use.
Q3: How does this pigment perform under thermal processing conditions?
A: This pigment exhibits good thermal stability, enabling safe use in standard polymer processing operations including injection molding and extrusion of polyolefins at typical temperatures up to approximately 240 °C. Performance may vary depending on residence time, shear history, and resin matrix, so process optimization is recommended during initial trials.
Q4: What is the recommended dosage range for achieving optimal color strength and dispersion?
A: Dosage depends on the target shade intensity, base polymer, and processing method. In most polyolefin masterbatches, effective loading typically ranges from 0.1% to 2% by weight. Lower concentrations are often sufficient for full-shade applications due to its high tinctorial strength; however, precise levels should be determined through laboratory-scale dispersion trials and spectral evaluation.
