Polycol WP-004 is a etherified polysaccaride with a very low viscosity mainly used as a thickener/rheology modifier for waterbased wall-paints, plasters and other waterbased coatings up to pH max. 11. Further to the thickening effect, Polycol WP-004 stabilises pigments and fillers and regulates the water retention (open time) after paint application. Solutions of Polycol WP-004 show nearly newtonian behaviour; i.e. the viscosity does almost not change with increasing shear-rate, independent of time (no thixotropy).
