  • Ca 2+ present in the surface sizing compositions influences the speed and amount of deposit formation.
  • the Ca 2+ is typically present in the paper pulp and concentrated in the paper product when it is (partially) dried in steps before the surface sizing is supplied to paper web.

Consequently, at steady state conditions the surface sizing composition may take up close to the maximum amount of Ca 2+ that will dissolve in said composition at the conditions prevailing during application to the paper web.
  • Typical Ca 2+ concentrations in the surface sizing composition may, for example, be from 1 to 1 ,000 mg/litre, such as between 5 and 200 mg/litre or between 5 and 100 mg/litre. With those typical levels of calcium ions the problems with deposit formation are particularly severe when ASA is used as a surface sizing agent.

  • the pH of the surface sizing composition can influence the speed and amount of deposit formation.

  • gypsum e.g. in an amount from about 0 to about 15 g/m 2 paper produced.
  • the surface sizing composition may be applied to the paper web by means of any suitable equipment, such as various kinds of size presses, usually positioned near to the end of a paper making process.
  • a size press is typically designed to comprise a two roll press with the paper web running between the rolls, for example with a hydraulic or pneumatic pressure system.
  • Any conventional size press can be used in the present invention and examples thereof include puddle size presses (also referred to pond size presses), film size presses and gate-roll size presses.

  • paper coatings may optionally be applied to the surface of paper, but that such paper coatings are completely different in function and composition from surface sizes.

Further, the fact that less deposits are formed shows that a composition prepared by separate addition of ASA and polymer has different properties compared to a composition in which the ASA has been dispersed in a polymer solution.
