TopBrane is a hyperbranched polymer with many reactive end groups that has been specifically developed as a water retention agent for precoat applications.
 .
Use of TopBrane in film press coating colors results in:
Better water retention and rheology behaviour (no dilatant behaviour)
Higher paper speeds, and/or higher solids
Reduction of visco-elasticy of the coating eliminating misting
Use of TopBrane in blade coated coating colors results in:
Better water retention
Fast and denser coating formation, no bleeding or beard building)
Higher coater speeds (up to 20 % increase realized)
Higher solids possible with equal rheology behaviour (63% to >70% realized)
More uniform and smoother paper
