Main advantages of liquid color systems include: • Excellent statistical distribution for consistently high quality products • Shot-to-shot and batch-to-batch consistency • Single heat history • Minimal wastage due to high level dosing accuracy and product recovery rates • Highly concentrated formulations with capability of very low addition rates • Reduced inventory and storage requirements CHARACTERISTICS OF HIGH PERFORMANCE STABLE LIQUID FORMULATIONS Under storage • Remains stable • Solid-like at low shear • No sedimentation During dosing • Exceeds yield stress • Liquid-like behavior • Flows easily After dispensing • Self-levelling • Rebuilds its structure INSPIRATION AND INSIGHT When developing a brand new color, consulting with your color provider early in the decision process can prove invaluable in gaining insight into which formulation will be most effective and can open up new ideas and opportunities for new colors, color effects, polymer options or finishes that you may not be familiar with. Product packaging is recyclable with recovery rates of up to 99%. Avient liquid color and additives in combination with state-of-the-art dosing equipment deliver extremely high dosing accuracy, reduced material usage and product recovery rates of 99+%.
