| Abstract | Binders are among the most expensive components of a coating formulation. In order to optimize their use, only the amount required to achieve the minimum strength should be used. The binder dosage itself has its own limitations. Abundant amount of binders diminish the optical properties of paper, consecutively insufficient amount of binders affect the binding strength and paper smoothness. Two pigment properties that directly affect binder demand are: dispersion and packing fraction. Theoretically, higher pigment packing ability indicates lower binder demand. Pigment packing ability is mostly affected by its size and shape, therefore Ground calcium carbonate and Kaolin Clay, major pigments used in mills, were chosen as a comparison. Relatively higher packing ability could be achieved by using kaolin clay. However, some optical properties, except gloss, did not show any advantages of using kaolin clay as single pigment. Mixing GCC in proper amount with kaolin clay could reduce the binder demand, instead of enhancing its gloss properties. |
