– VN – 6505 : especially used for spray applications between layers of paper and paper surface. It
improves mechanical properties of the paper such as burst strength, ring crush, poly bonding of
the layers of paper after the drying stage.
– Dosing rate: Mix starch powder with water at a concentration of 1 to 3 %, filtered through a 90
mesh sieve, then use pressure pump adding from 3 to 4 kgf/cm² with pressure control valve to
