APPLICATION

IN THE MASS
UMATON  ABPX  is universally acceptable for brightening sized and filled papers. Its good resistance to acid and sizing reliable processing event at Low  pH. In clay filled papers UMATON ABPX POWDER IS highly effective at medium filter addition. It is adisable to prepare a highly dilute solution and to add it slowly to prevent mottling. Usually 0.2% to 0.3% UMATON ABPX    to the weight of pulp is sufficient for the whiteness but in special cases up to 1.2% of the weight of pulp can be used to get very high degree of whiteness. To obtain better whiteness we recommend that the additions should be made in the following order.

 

 IN THE PAPER SURFACE
UMATON ABPX is suitable for surface sizing with starch. In many cases the effect can be further  improved by adding small amounts of  carboxy  methyl cellulose to the starch solution.
Outstanding brightening effects are obtained in pigment coating compounds especially those
containing starch and bio and synthetic binders.
