  • METHOD AND SYSTEM USING LOW FATTY ACID STARCHES IN PAPER SIZING COMPOSITION TO INHIBIT DEPOSITION OF MULTIVALENT FATTY ACID SALTS
    Publication number: 20140102654
    Abstract: A method for inhibiting deposition of multivalent saturated fatty acids on paper sizing equipment and/or devices which use a paper surface sizing composition containing higher starch solids levels of surface sizing starches and a source of multivalent cations, such as a multivalent metal drying salt, by including (wholly or partially) one or more low fatty acid surface sizing starches in the paper surface sizing composition. Also, a paper surface sizing system for carrying out this method.
