Aldirez®-211
Aldimine curing agent
Aldirez®-211 is a bis-aldimine which, upon contact with moisture, yields a diamine to act as a crosslinker for isocyanates in polyurethane or polyaspartic products.
Prevents the production of CO2 gassing which would result in bubbling and film defects, even at elevated temperature and humidity. Extends the pot life in 2k polyisocyanate systems with minimal impact on film cure speed.
