摘要：
The influence of the rheological properties on the spraying behavior of an adhesive polyurethane dispersion modified with different thickeners was investigated. The differences in shear rheology for the three different kinds of thickeners were found not to be representative for the spraying behavior. The extended fan sheets and reduced overspray for the water-soluble thickener correspond to a more pronounced elastic rheological behavior of the dispersion.
