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.
