Trixene® Aqua BI 220 G is a stable, non-ionic dispersion of a blocked aliphatic polyisocyanate in water. Trixene Aqua BIs are designed as crosslinkers used in one component (1K) waterborne coatings as well as for adhesion promotion. They are typically dried and cured under factory stoving conditions which allows crosslinking with suitable hydroxyl-functional resins.
