PolyAziridine Global PZE-1000 is an ethylene imine based tri-functional polyaziridine that is used as a cross-linker for both aqueous and non-aqueous coatings, inks, and adhesives to promote both physical and chemical properties. With the highest level of functionality at 3.3, it yields the highest level of cross-link density of polyfunctional aziridines. The aziridine end groups can react with active hydrogen as found on carboxyl groups of acrylic emulsions or polyurethane dispersions. PZE-1000 also has a hydroxyl group, which allows it to dispersion readily into aqueous systems. PZE-1000 is added at levels of 1% to 3% to finished formulated coatings, inks, or adhesives. It is added slowly and under good agitation. After mixing, an aqueous system with a pH of 9.0-9.5 will typically have a pot life of 18-36 hours. This time will be reduced when the pH is lower.

PolyAziridine Global PZBI-25 is a cross linker agent that improves bonding and cohesive strength of resins and binders, resulting in films with better resistances, particularly scratch resistance, abrasion, hydrolysis and general chemical resistances. As a blocked isocyanate, the blocking end groups can react with active hydrogen as found on carboxyl groups of acrylic emulsions or polyurethane dispersions. An interesting feature is that no CO2 is released.
