Q1: What types of polymer systems is this color paste compatible with?
A: Hostatint Red A-P2Y 100-ST VP 5470 is specifically formulated for use in polyolefin-based systems, including PP and HDPE, and demonstrates good compatibility in certain engineering thermoplastics. It is not recommended for highly polar or hydrophilic matrices such as PET or PA without prior compatibility testing.
Q2: How should this color paste be incorporated into the polymer melt?
A: The paste is designed for direct addition during compounding or injection molding processes. It can be metered using standard gravimetric or volumetric dosing equipment. Pre-mixing with a small portion of base resin prior to main extrusion is recommended to ensure uniform dispersion.
Q3: Is this product suitable for food-contact applications?
A: This grade is intended for non-food-contact applications unless explicitly certified for such use in your target market. Regulatory compliance must be verified case-by-case with local authorities and end-use specifications — Clariant does not provide blanket food-contact approval for this formulation.
Q4: What is the typical dosage range for achieving strong red shades in polypropylene?
A: Dosage depends on the desired shade intensity and base resin characteristics, but typical usage generally ranges from 0.1% to 2% by weight. Stronger chroma is achievable at the higher end, while pastel tones may require lower concentrations and careful dispersion control.
