Q1: What is the primary application area for Hostatint Yellow A-H3G 100?
A: Hostatint Yellow A-H3G 100 is a high-performance organic pigment-based color paste designed primarily for coloring polyolefin compounds—especially PP and PE—in applications requiring good thermal stability, dispersion quality, and consistent hue reproducibility during extrusion and injection molding.
Q2: Is this color paste suitable for food-contact or pharmaceutical packaging applications?
A: Hostatint Yellow A-H3G 100 is formulated without heavy metals and complies with general regulatory expectations for indirect food contact in polyolefins, subject to final formulation validation. Customers must verify compliance with applicable regional regulations—including migration testing—as part of their own regulatory dossier.
Q3: How should this paste be incorporated into polyolefin compounds?
A: It is typically added directly to the polymer melt during compounding using standard twin-screw extruders. Good mixing intensity and residence time are recommended to ensure uniform dispersion. Pre-blending with carrier resin or masterbatch dilution may be used depending on equipment and target concentration.
Q4: What is the typical dosage range for achieving full opacity or strong chroma in PP?
A: Dosage depends on the desired shade strength, base polymer, and processing conditions, but it is generally used at low concentrations—typically ranging from 0.1% to 2% by weight—to achieve robust yellow coloration with excellent tinctorial strength and minimal impact on mechanical properties.
