Q1: What is the primary application field for Hostatint Blue A-BG 100 Color Paste?
A: Hostatint Blue A-BG 100 is specifically developed for coloring polyolefin-based packaging materials, including flexible films, blow-molded containers, and injection-molded closures—particularly where high chroma, excellent dispersion, and thermal stability during processing are required.
Q2: Is this color paste suitable for food-contact applications?
A: Yes, Hostatint Blue A-BG 100 is formulated to comply with global food-contact regulations for polyolefins, subject to final formulation validation and compliance with applicable regional requirements. It contains no intentionally added heavy metals or restricted substances per Clariant’s current product stewardship guidelines.
Q3: How does Hostatint Blue A-BG 100 perform under high-shear and high-temperature processing conditions?
A: The paste exhibits robust thermal and mechanical stability, maintaining color integrity and minimizing pigment agglomeration during extrusion, injection molding, and blow molding of polypropylene and polyethylene—especially at melt temperatures up to 260 °C.
Q4: What is the recommended dosage range for optimal color development?
A: Dosage depends on the desired shade depth and base polymer, but it is typically used at low concentrations—generally ranging from 0.1% to 2% by weight—due to its high tinctorial strength and efficient dispersion in polyolefin matrices.
Q5: Can Hostatint Blue A-BG 100 be blended with other Hostatint color pastes?
A: Yes, it is fully compatible with other Hostatint color pastes based on similar polyolefin-compatible carrier systems, enabling broad shade tuning. However, compatibility should always be verified in the final application matrix prior to full-scale production.
