Coatex Viscoatex 46 Thickener

Coatex Viscoatex 46 is a high-performance associative thickener from Coatex’s Viscoatex series, designed for waterborne coatings and inks. It delivers excellent rheology control, sag resistance, and spatter suppression while maintaining low viscosity at high shear. Compatible with acrylics, vinyl acetates, and styrene-acrylics, it ensures stable viscosity across pH 3–12 without requiring neutralization.
