Abstract Aminated tannins were prepared by reacting mimosa condensed tannin extract with ammonia yielding the substitution of many, if not all of the tannin hydroxyl groups with –NH2 groups. A tannin-aminated tannin (ATT)
particleboard coating was then prepared by reacting raw tannin extract with aminated tannin extract and thus
cross-liking the two by substituting tannin’s hydroxyl groups with the –NH2 groups on the aminated tannin to
form –NH-bridges between the two. The resulting particleboard coating gave encouraging results when pressed
at 180°C for 3 min. Conversely, the system in which tannin was reacted/cross-liked with urea (ATU) by… More >
