BERSET® 2169 is a blocked crosslinker. The partially blocked chemistry of BERSET® 2169 provides a stable viscosity during the coating color preparation. The reactivity of BERSET® 2169 is greatly accelerated during the drying process, thus resulting is high wet rub and wet pick resistance at the reel. BERSET® 2169 crosslinks all synthetic and natural binders, resulting in a high degree of wet rub and wet pick resistance off machine. However, as with all glyoxal based crosslinkers, BERSET® 2169 is the most efficient at crosslinking starch based coatings.
Proprietary blocked chemistry prevents yellowing and controls wet state viscosity in starch binders
