Clariant Hostatint Black GR-T 500 VP 3976 Color Paste – Frequently Asked Questions (FAQ)

Q1: What is the primary application field for Hostatint Black GR-T 500 VP 3976?

A: This pigment paste is specifically developed for coloring polyolefin-based packaging materials, including flexible films and rigid containers used in food, pharmaceutical, and consumer goods applications — where high thermal stability, dispersion quality, and low extractables are critical.

Q2: Is this product suitable for use in food-contact compliant formulations?

A: Yes, Hostatint Black GR-T 500 VP 3976 is designed to support regulatory compliance in food-contact applications. It is formulated without heavy metals or restricted aromatic amines, and its base polymer carrier is selected for compatibility with global food-contact guidelines — though final compliance depends on the full formulation and processing conditions.

Q3: How does this paste perform during high-temperature processing such as extrusion or injection molding?

A: The paste exhibits excellent thermal stability up to typical polyolefin processing temperatures (e.g., 220–260 °C), with minimal color shift or degradation. Its optimized rheology and pre-dispersed pigment structure help maintain color consistency and reduce filter pressure buildup during continuous extrusion.

Q4: What is the recommended dosage range for achieving optimal black intensity and dispersion?

A: Dosage depends on the substrate, required opacity, and processing method, but it is typically used at low concentrations — generally ranging from 0.1% to 2% by weight in polyolefin masterbatches or direct-add applications. Lower dosages often suffice due to the high pigment loading and efficient dispersion of the paste.

Q5: Can this product be used in combination with other Hostatint color pastes or additives?

A: Yes, Hostatint Black GR-T 500 VP 3976 is compatible with other Hostatint pigment pastes and common polyolefin additives (e.g., antioxidants, UV stabilizers) when properly incorporated. However, compatibility testing under actual processing conditions is recommended to confirm color fidelity and physical performance in multi-component systems.
