Usage Instructions

Recommended dosage: 0.3–3.0% depending on color strength and application. For plastics/masterbatch, pre-disperse with suitable carrier resin and dispersant; for inks/coatings, mill to target fineness. Processing temperature should be controlled below 160°C (system dependent). Ensure good ventilation and use appropriate PPE. Store sealed in a cool, dry place.
