Size press compositions and methods for producing sized paper products, including liner board are disclosed. The Size press compositions contain at least one non-reactive cationic surface sizing agent at least one reactive sizing agent, at least one promoter resin, at least one binder, and water. The at least one non -reactive cationic surface sizing agent may be a polymer in the form of a dispersion, an emulsion or a latex with a positive zeta potential below about pH6. The at least one reactive sizing agent may be a dispersion, an emulsion or a latex including an alkyl ketene dimer or an alkyl succinic anhydride. The at least one promoter resin may be a polyaminoamide-epichlorohydrin resin or poly (dimethyldiallylammonium chloride). |
