Ecodis™ P 30-30

Arkema Rheology & Specialty Additives

Dispersion paints are usually formulated with fillers or extenders, particularly the very fine calcium carbonates and clays now available. Their dispersion in water based systems must be achieved easily with common stirrers without forming agglomerates or causing a viscosity build up. Usual inorganic dispersants, such as phosphate-based dispersants, are not able to solve this problem satisfactorily: their deflocculating effectiveness is limited by the fineness of the extenders used, and their poor temperature stability (degradation through hydrolysis) affects the long-term stability of paints. Ecodis™ P 30-30 has been especially developed to overcome these problems. It ensures the complete dispersion of extenders and inorganic pigments at high solids contents in systems showing medium to high PVC (Pigment Volume Concentration).
