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).
Using Polycol WP-004, it is possible to formulate waterborne paints/coatings with a final viscosity similar to such ones containing cellulose-ethers (very low grades). The optimal concentration of Polycol WP-004 has to be deter-mined by the user himself within his own formulations. Usually the dosage range in wall paints is around 0.4-1.5%. Components containing borates in the formulation are to be strictly avoided: gelification may occur!
