Abstract

Basic studies were conducted to understand the rheological properties of the coating colors and effectively utilize the information obtained from the rheometric test. For this purpose, the understanding and interpreting method for the interaction mechanism between the coating components were examined using the analyzing method of the viscosity and viscoelastic property of the coating colors. The coating solution exhibited shear thinning behavior as shear rate increased. The slope of the elastic curve (viscoelastic characteristic) of the coating color in the low frequency region (10-1-100(rad/s)) was considered to be correlated with the strength of the interaction of the coating components. Although it was believed that the rheological properties of coating color independently influenced by the individual factors such as the binder type and the pigment packing structure (pigment mixture composition), the interaction of two or more factors may also have a complicated effect on the rheology of the coating color.
