WATERBORNE COATING COMPOSITIONS

摘要

The present invention is directed to a waterborne coating composition prepar ed from liquid blend raw materials, such as titanium dioxide slurries, extender pigment slurries, thickener slurries, glycol slurries, and latex binders. The liquid blends have substantially the same viscosity characteristics as the final waterborne coating composition, in the range of about 70-125 Krebs units. The method for preparing the waterborne coating composition of the invention comprises providing a plurality of the liquid blend raw materials and admixing the liquid blend raw materials to produce the waterborne coating product. This invention is also directed to pigment slurry compositions useful in liquid blend systems, and the method for preparing the slurries.
