HELSINKI, Dec. 9, 2019 (Press Release) -PankaMax will be produced with all fiber layers hard sized from beginning of December 2019 onwards.
This means that the Cobb 30 min values are maximum 90 g/m2.
Studies carried out with research laboratories and experiences from customer projects have confirmed that hard sizing is improving the board’s performance in laminated end uses. Thanks to the hard sizing, the lamination glue will remain better in the surface layer of PankaMax enabling more uniform and stronger bonding between PankaMax and the surface material. In addition, when the water-based glue is penetrating less into the board, the tendency to curl is also minimized.
