Q1: What is the primary application field for Hostatint Violet A-RL 100 Color Paste?
A: Hostatint Violet A-RL 100 is specifically developed for coloration of polyolefin-based packaging materials, including flexible films and rigid containers used in food, personal care, and household product applications. It offers excellent dispersion stability and thermal resistance during extrusion and thermoforming processes.
Q2: Is this color paste suitable for food-contact applications?
A: Yes, Hostatint Violet A-RL 100 is formulated to comply with global regulatory frameworks for indirect food contact, including FDA 21 CFR and EU Framework Regulation (EC) No 1935/2004. Its compliance status is verified through Clariant’s internal migration testing protocols and documented in the product’s regulatory dossier.
Q3: How should the paste be incorporated into polyolefin compounds?
A: The paste is typically introduced via masterbatch dilution or direct addition during compounding—most commonly using twin-screw extrusion. For optimal dispersion, pre-mixing with a portion of the base polymer prior to extrusion is recommended. Dosage depends on formulation requirements but generally ranges from 0.1% to 2% by weight of the final compound.
Q4: Does Hostatint Violet A-RL 100 exhibit good lightfastness and heat stability?
A: Yes, it demonstrates very good thermal stability up to typical polyolefin processing temperatures (e.g., 220–260 °C), with minimal color shift. Lightfastness performance is rated as good to very good under standard ISO 105-B02 exposure conditions, particularly when used in opaque or pigmented systems.
