Q1: What types of polymer systems is Hostatint Red E-E3B Color Paste compatible with?
A: Hostatint Red E-E3B is specifically formulated for use in polyolefins (e.g., PP and PE), as well as certain engineering thermoplastics such as ABS and PS. It demonstrates good thermal stability during standard melt processing conditions and offers consistent dispersion without significant plate-out.
Q2: Is this color paste suitable for food-contact applications?
A: Hostatint Red E-E3B is designed for non-food-contact applications. It is not certified for direct or indirect food contact under major regulatory frameworks such as FDA 21 CFR or EU Framework Regulation (EC) No 1935/2004. For food-contact uses, Clariant offers dedicated, fully compliant pigment solutions upon request.
Q3: How should the paste be incorporated into a polymer formulation?
A: The paste is typically introduced via masterbatch dilution or direct addition to the base polymer during compounding. For optimal dispersion, pre-mixing with a portion of the carrier resin before extrusion is recommended. Dosage depends on formulation requirements but generally ranges from 0.1% to 2% by weight relative to the final compound.
Q4: Does Hostatint Red E-E3B offer UV resistance in outdoor applications?
A: While the pigment exhibits moderate lightfastness in typical indoor environments, it is not optimized for long-term UV exposure without additional stabilization. For demanding outdoor applications, we recommend pairing it with appropriate UV absorbers and HALS stabilizers to enhance durability.
