Q1: What is the primary chemical composition of CATHAYGRAN Black F9635GS?
A: CATHAYGRAN Black F9635GS is a high-performance inorganic black pigment based on mixed metal oxides, engineered for thermal and chemical stability. Its exact formulation is proprietary, but it contains no heavy metals of concern such as lead, cadmium, or mercury, and complies with global regulatory expectations for industrial pigments.
Q2: Is this pigment suitable for use in polyolefin compounds, especially during high-temperature processing?
A: Yes — CATHAYGRAN Black F9635GS is specifically designed for demanding polymer applications, including polypropylene and polyethylene. It exhibits excellent thermal stability up to typical melt-processing temperatures and demonstrates strong dispersion behavior without significant color shift or degradation under standard extrusion or injection molding conditions.
Q3: How does this pigment perform in terms of UV resistance and weathering stability?
A: As an inorganic oxide-based black pigment, CATHAYGRAN Black F9635GS offers inherently high UV resistance and long-term outdoor durability. It is widely used in applications requiring consistent color retention and minimal chalking or fading under prolonged exposure to sunlight and environmental stressors.
Q4: What are the recommended handling and dispersion guidelines for optimal performance?
A: For best results, pre-blending with carrier resin or masterbatch dilution is recommended prior to final compounding. The pigment should be introduced during the early stages of melt processing to ensure uniform distribution. Avoid excessive shear or extended residence time at peak temperature to preserve dispersion integrity and minimize potential agglomeration.
