PZE-1000 is an ethylene imine based tri-functional polyaziridine (XAMA® 7 equivalent) that is used as a crosslinker 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.
