| Abstract | The function of insolubilizers or crosslinkers is to add water resistance of coated paper. Water resistance is very important in offset printing. Insolubilizers can affect coating color dewatering ability and improve some properties of coated paper surface. In this study, more focus is given on comparison of ammonium zirconium carbonate (AZC), potassium zirconium carbonate (PZC) with glyoxal used in paper coating. Making various coating color formulations based on control pH, Brookfield viscosity and solid content in a preferable range. Make coating paper by rod metering method. Coating color and coated paper were produced by using AZC, PZC and glyoxal respectively. Composition of pigments, kaolin, PCC and GCC, was varied from formulations. On the other hand, SB latex was used with CMC as binder in formulations as well as SB latex and starch used as mixed binders. Brookfield viscosity and water retaining ability and surface properties of coated paper were measured. The results show that changing the dose of insolubilizers had various effects on coating color and coated paper properties, except the brightness. AZC and PZC are more preferable to improve surface properties of coated paper |
