Collacral PU 85 Solution of diurethane BASF Flow / Levelling agent Rheology Modifier/ Thickener >> Associative >> Urethane (HEUR) Coatings >> Waterborne Architectural / Decorative Water/butyldiglycol Collacral PU 85. Solution of diurethane (approx. 25%) in water/butyldiglycol. Very pronounced thickening effect with low particle size anionic polymer dispersions. Minimal spatter during roller application. Resistance to water affected only slightly. Watermiscible solvents favour Newtonian flow and good levellling; for architectural finishes and satin gloss emulsion paints. Thickener.
