Q1: What types of polymer systems is this color paste compatible with?
A: Yingcai Chroma-chem 844 is formulated for broad compatibility with common thermoplastic and thermoset resins, including polyolefins (PP, PE), ABS, PS, PVC, and engineering plastics such as PC and PA. Performance may vary depending on processing conditions and base resin polarity, so preliminary compatibility testing is recommended.
Q2: How stable is the dispersion under high-shear or elevated-temperature processing?
A: The paste features a robust, non-ionic dispersant system designed to maintain pigment integrity during extrusion, injection molding, and compounding. It demonstrates good resistance to shear-induced degradation and thermal stress up to typical polymer processing temperatures, supporting consistent color development and minimal plate-out.
Q3: Is this product suitable for applications requiring high lightfastness and weather resistance?
A: Yes — as a quinacridone-based red, Chroma-chem 844 offers inherently excellent lightfastness and UV stability. It is well-suited for outdoor applications and long-term color retention where exposure to sunlight and environmental stressors is expected, though final performance depends on the host matrix and formulation additives.
Q4: What is the typical dosage range for achieving full opacity or strong chroma in standard polymer applications?
A: Dosage depends on the desired shade intensity, substrate transparency, and processing method, but it is generally used at low concentrations — typically ranging from 0.1% to 2% by weight in most thermoplastic systems. For deep, saturated reds, lower dosages often suffice due to the high tinting strength of the quinacridone pigment.
