Q1: What is the primary application field for Hostasin Red HF2B 30 Color Paste?
A: Hostasin Red HF2B 30 is a high-performance organic pigment dispersion specifically developed for coloring polyolefin-based packaging films, including flexible food packaging and non-food industrial films, where good heat stability and migration control are required.
Q2: Is this color paste suitable for direct food contact applications?
A: Yes — Hostasin Red HF2B 30 is formulated to meet global regulatory expectations for indirect food contact in polyolefins. It is designed to minimize extractables and comply with general safety principles for food packaging, though final compliance depends on the complete formulation and processing conditions.
Q3: How should Hostasin Red HF2B 30 be incorporated into polyolefin compounds?
A: It is typically added via masterbatch dilution or direct compounding using standard melt-processing equipment. Good dispersion is achieved under typical extrusion conditions for polypropylene or polyethylene, and dosage generally ranges from 0.1% to 2% by weight depending on the desired shade intensity and polymer matrix.
Q4: Does this paste contain heavy metals or halogenated compounds?
A: No — Hostasin Red HF2B 30 is free of regulated heavy metals (e.g., lead, cadmium, mercury, hexavalent chromium) and intentionally added halogens, aligning with Clariant’s commitment to sustainable and eco-preferred color solutions.
Q5: What storage conditions are recommended to maintain product stability?
A: Store in original sealed containers at temperatures between 5 °C and 30 °C, away from direct sunlight and sources of heat. Avoid freezing, and ensure lids are tightly closed after use to prevent skinning or moisture ingress.
